Description
Technical Field
The invention relates to the technical field of seismic exploration, in particular to a seismic source wired consistency testing method.
Background
The wired consistency test of the seismic source is an important basis for detecting the performance of the seismic source. The existing seismic source consistency test is to collect and record seismic source test data to an instrument through a seismic channel. Because the amplitude of the output signal of the DSD wired test of the electric cabinet body is larger during the seismic source consistency test, important production parameters, namely default seismic channel gains, need to be modified in order to prevent signals from being 'clipped', so that the seismic source consistency test cannot be performed simultaneously during production, and the production cannot be performed when the seismic source consistency test is performed. In addition, since the seismic traces have fixed line numbers and stake marks, the test range needs to be fixed in a certain wire harness range, and the line numbers and stake marks corresponding to the seismic source and the seismic source data thereof need to be recorded. The seismic sources also need to be gathered at selected positions (big and small in front and back rows) for long distance running from each arranged position, the running distance is generally 6-7 km, and the number of the seismic sources at each position is 6-10. If the source at a certain position cannot pass the test once, the field position information needs to be repeatedly tested and verified, the arrangement and instrument parameters cannot be recovered until all the source consistency tests pass, and the production can not be started until the source returns to the original position.
In the high-efficiency large-channel number acquisition project, a mode of simultaneous construction of multiple wire harnesses and front and back rows is generally adopted, so that the number of source allocation is generally about 32. Because the traditional wired consistency test of the seismic source is completed on the basis of production stoppage, each test needs to occupy about 3 hours of effective production time, and personnel and equipment investment is more. In addition, in the efficient collection project, as long as production stoppage is involved, the working pressure of the relevant teams is increased virtually, and the higher the pressure is, the higher the safety risk is, and the probability of error is increased.
There is no method in the prior art that can perform wired consistency testing at the same time when the seismic source is normally produced.

The earthquake source vehicle receives an earthquake starting signal of the instrument host, the earthquake source Che Qi is used for producing, a production arrangement cross station CX1 in the production arrangement collects data, and the collected data is transmitted to the instrument host, so that the normal production process is realized. The earthquake focus vehicle can receive the control signal of the instrument host, and start or stop according to the control signal of the instrument host; the seismic source vehicle and the instrument host are connected in a wireless mode, a wireless local area network is established at the construction site, the whole construction site is covered, and the instrument host can control the seismic source vehicle through the wireless local area network; the seismic source vehicle and the instrument host can be connected in a wired mode, and the seismic source vehicle can be connected with the instrument host through optical fibers when in implementation, and the instrument host transmits various control signals to the instrument host.
To ensure that the source vehicle is capable of performing a source wire consistency test during normal production, in an embodiment, a simulation auxiliary channel needs to be established in a secondary arrangement. Because the seismic channel gain of the analog auxiliary channel is not limited by the default seismic channel gain, the analog auxiliary channel can be different from the production seismic channel gain, so that the situation that all the seismic source vehicles are stopped due to modification of the production seismic channel gain can be avoided, the seismic source wired consistency test is carried out on the seismic source vehicles in normal production, the auxiliary channel does not need line numbers and pile numbers, only the auxiliary channel is needed to be cut into the production arrangement of production, and the instrument host machine identification can be used for testing. Thus, a simulated auxiliary channel may be created in the secondary arrangement, which is cut into the production arrangement.
After the simulation auxiliary channel is established, in the embodiment, the test shot processing type is required to be modified from the production processing type to the test processing type next; when the vibration source is producing, the processing type of the shot point to which the vibration source belongs is the production processing type, and the vibration source vehicle to be subjected to the vibration source wired consistency test needs to be modified into the test processing type so as to distinguish different states of the vibration source vehicle and carry out different control: when the shot point of the seismic source vehicle is in the production processing type, the seismic source vehicle is normally produced; and when the shot point of the seismic source vehicle is in the test processing type, the seismic source vehicle performs wired consistency test. In one embodiment, the test processing class includes a consistency processing type and a pulse processing type. In an example of an embodiment of the present invention, in the Process of setting the 508XT acquisition system and the source vehicle, the code of the consistency processing Type (Process Type) is 3, the code of the pulse processing Type (Process Type) is 6, and the code of the production processing Type (Process Type) is 4. When the cable consistency test of the seismic source is carried out according to the test plan, on the day of carrying out the test plan, the shot points which are finished in production are processed to be test shot points, the processing type of the test shot points is changed from the production processing type to the test processing type, and the setting of the shot points is completed.
After modifying the test shot point processing type from the production processing type to the test processing type, selecting a source vehicle to be tested, wherein in the embodiment, a group of test source vehicles is selected from a plurality of source vehicles to which the test shot point belongs. The shot points are a coordinate range in production, and are displayed in a point on an instrument host, each shot point comprises a plurality of source vehicles, and the source vehicles are arranged in the shot points according to the set construction positions. When the method for testing the wired consistency of the seismic source is carried out, only the selected testing seismic source vehicle is required to be operated, other seismic source vehicles still carry out normal production according to the original construction plan, therefore, a group of testing seismic source vehicles are required to be selected from a plurality of seismic source vehicles which are provided with testing shots, the wired consistency of the seismic source is only tested for the group of testing seismic source vehicles, and other non-selected seismic source vehicles carry out normal production, so that the testing and the production can be synchronously carried out, the T-D rule in production is met, and the T-D rule is not influenced; in an embodiment, after the set of test source vehicles is selected, the set of test source vehicles is parked, and the corresponding set of source vehicles is also displayed on the instrument host in preparation for the source wire consistency test.
After the test source vehicles are selected, the secondary arrangement is required to be connected with the test source vehicles, and in the embodiment, when the production arrangement cross station CX1 is arranged in the test range of the group of test source vehicles, the secondary arrangement is set into a test mode, and the production arrangement cross station CX1 is connected with the group of test source vehicles; associating the test shots to the set of test source vehicles and associating the set of test sources Che Qizhen; the secondary array collects source consistency test data for the set of test source vehicles via the analog auxiliary channels and transmits the data to the instrument host via the production array cross station CX1. When performing a wired consistency test of a seismic source, determining a test range of the group of test seismic source vehicles; the test range is determined by shot distribution, seismic source distribution, production arrangement distribution, seismic source vehicle performance parameters and the like which are divided by a construction plan in specific construction. When the production arrangement cross station CX1 exists in the test range of the selected group of test source vehicles, setting the secondary arrangement as a test mode; the secondary arrangement has two modes of operation: the test mode and the data acquisition mode, the initial default working mode of the secondary arrangement is the test mode, if the data acquisition mode needs to be set, the secondary arrangement needs to be connected with an instrument host, and the secondary arrangement is set through the instrument host, which specifically can comprise: connecting the secondary arrangement with an instrument host, detecting the accessed secondary arrangement by the instrument host, establishing a connection relation, identifying an initial working mode of the secondary arrangement as a test mode, displaying device identifiers of the secondary arrangement on the instrument host after establishing the connection relation, selecting the device identifiers of the secondary arrangement, clicking GO beside an acquisition, and completing the conversion from the test mode to a data acquisition mode. In an embodiment, the conversion from the test mode to the data acquisition mode may be performed on a computer provided in the host computer of the apparatus. If the secondary arrangement is required to be converted from a data acquisition mode to a test mode, one method is to restart the secondary arrangement, and the secondary arrangement can restore the initial default test mode; the second method is to power down the secondary arrangement, which will also resume the default test mode when power is re-turned on. After the secondary arrangement is set to a test mode, as shown in a test schematic diagram when a production arrangement cross station CX1 is provided in a test range in the method for testing the wired consistency of the seismic source in the embodiment of the invention in fig. 2, the secondary arrangement is connected with the production arrangement cross station CX1 and the group of test seismic source vehicles, namely, the seismic source vehicles are connected with the production arrangement cross station CX1 through the secondary arrangement; then, the testing shot points are associated with the group of testing seismic source vehicles on the instrument host, the instrument host sends a seismic start signal to the seismic source vehicles, and the group of testing seismic sources Che Qizhen; the secondary arrangement collects the focus consistency test data of the group of test focus vehicles through the simulation auxiliary channel, and transmits the focus consistency test data to the instrument host through the connected production arrangement cross station CX1 to complete the collection of primary test data; after the wired consistency test of the vibration source of the group of test vibration source vehicles is finished, replacing other test vibration source vehicles, and performing wired consistency test of vibration source on other test vibration source vehicles; the set of seismic source vehicles which are tested is controlled to be restored to the working state of normal production through the arrangement of the instrument host.
Since the shot distribution, the source distribution and the production arrangement distribution are different according to the construction plan, and the working positions of the source vehicles are not provided with the production arrangement intersection CX1 in the test range, another test method is needed in the embodiment: when the production arrangement cross station CX1 is not in the test range of the group of test source vehicles, setting the secondary arrangement as a data acquisition mode, and connecting the group of test source vehicles; associating the test shots to the set of test source vehicles and associating the set of test sources Che Qizhen; the secondary arrangement collects the focus consistency test data of the group of test focus vehicles through the simulation auxiliary channel, searches for the next production arrangement cross station CX1 and is connected, and the focus consistency test data of the group of test focus vehicles is transmitted to the instrument host through the connected production arrangement cross station CX1. According to the setting method of the secondary arrangement, the secondary arrangement is set as a data acquisition mode: connecting the secondary arrangement with an instrument host, detecting the accessed secondary arrangement by the instrument host, establishing a connection relation, identifying an initial working mode of the secondary arrangement as a test mode, displaying device identifiers of the secondary arrangement on the instrument host after establishing the connection relation, selecting the device identifiers of the secondary arrangement, clicking GO beside an acquisition, and completing the conversion from the test mode to a data acquisition mode. As shown in the test schematic diagram of the test method for the wired consistency of the seismic source in the embodiment of the invention in the test range when the production arrangement cross station CX1 is not generated, the production arrangement cross station CX1 is not generated in the test range, so that in the first step, synchronous test is carried out, and only the two-level arrangement is connected with the group of test seismic source vehicles; then, the testing shot points are associated with the group of testing seismic source vehicles on the instrument host, the instrument host sends a seismic start signal to the seismic source vehicles, and the group of testing seismic sources Che Qizhen; the secondary arrangement collects consistency test data of the group of test seismic source vehicles through the simulation auxiliary channel, and the seismic source consistency test data are temporarily stored in a secondary arrangement intersection CX 2; and then, carrying out a second step of data recovery, after the acquisition of the focus consistency test data of the group of test focus vehicles is completed, searching for the next production arrangement cross station CX1 according to a test plan, connecting the second-level arrangement with the production arrangement cross station CX1, and transmitting the stored focus consistency test data of the group of test focus vehicles to an instrument host through the connected production arrangement cross station CX1 to complete the acquisition of primary test data. After the wired consistency test of the vibration source of the group of test vibration source vehicles is finished, replacing other test vibration source vehicles, and performing wired consistency test of vibration source on other test vibration source vehicles; the set of seismic source vehicles which are tested is controlled to be restored to the working state of normal production through the arrangement of the instrument host.

In the embodiment, the two-level arrangement cross station CX2 is connected with two large wires through an optical cable; in the embodiment, two source vehicles are generally adopted as a production group during production, so that when the wired consistency test of the source is carried out, one production group, namely two source vehicles, can be selected as a group of test source vehicles for faster wired consistency test; in the specific implementation, more than two source vehicles can be connected and selected as a group of test source vehicles, and the two source vehicles are not used as limitations. The secondary arrangement comprises a secondary arrangement cross station CX2 and large lines Link, and each large line Link comprises 4 field digital acquisition units FDU; when two source vehicles are selected as a group of test source vehicles, the corresponding secondary arrangement also needs to comprise two large lines Link, and at the moment, the secondary arrangement comprises 8 field digital acquisition units FDU. In the implementation, the number of large lines Link included in the secondary arrangement is not limited to two, and is determined by the number of the selected group of test source vehicles, for example, if the selected test source vehicles include 3 large lines Link corresponding to the secondary arrangement are 3, and the number of field digital acquisition units FDU included in the secondary arrangement is 12; if the number of the selected test seismic source vehicles is 4, the number of large lines Link corresponding to the secondary arrangement is 4, the number of the field digital acquisition units FDU is 16, and so on.
