Detailed Description

the following detailed description of the embodiments of the present invention will be provided with reference to the drawings and examples, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented. It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.

FIG. 1 shows a flow chart of a power management while drilling method according to an embodiment of the invention. As shown in fig. 1, the method for power management while drilling according to the embodiment of the present invention mainly includes steps 101 to 104.

in step 101, the environmental pressure to which the measurement-while-drilling system is subjected is monitored.

in step 102, it is determined whether the environmental pressure is less than a preset starting pressure, where the starting pressure is the environmental pressure that the measurement-while-drilling system is subjected to when the measurement-while-drilling system is located at the bottom of the well.

In step 103, when the environmental pressure is judged to be less than the starting pressure, the measurement while drilling system is controlled to be in a dormant state.

in step 104, when the environmental pressure is judged to be greater than or equal to the starting pressure, the measurement while drilling system is controlled to be in the working state.

Specifically, in order to optimally manage the power supply of the measurement while drilling system, a set of identification systems of the state of the measurement while drilling system is needed first. The most effective state identification of the measurement-while-drilling system is pressure, the pressure measurement and monitoring are utilized to identify the approximate position of the measurement-while-drilling system in a shaft, and whether the whole measurement-while-drilling system is started or not can be further determined.

The specific implementation process is as follows:

Firstly, a starting pressure value for starting the measurement while drilling system needs to be set on the ground (off-line), and the measurement while drilling system is controlled to be started only when the environmental pressure of a shaft where the measurement while drilling system is located is greater than or equal to a preset starting pressure.

In the process of drilling down the measurement while drilling system, monitoring that the environmental pressure of the measurement while drilling system is always smaller than the starting pressure, and then controlling the measurement while drilling system to be in a dormant state all the time. The measurement while drilling system in the dormant state does not work, and the electric power stored by the power supply while drilling is not consumed.

When the measurement while drilling system is adjacent to or reaches the bottom of the well, if the pressure of the environment of the shaft where the measurement while drilling system is located is monitored to exceed the starting pressure value, a power supply channel of the measurement while drilling system is opened at the moment, the measurement while drilling system is controlled to be in a working state, and the measurement while drilling system starts to perform relevant measurement and transmission.

when the tripping is started, the mud pump is stopped, and when the pressure of the environment of the shaft where the measurement while drilling system is positioned is monitored to be less than the starting pressure, the measurement while drilling system is in a dormant state by turning off the power supply of a power supply (battery) while drilling.

By applying the power management method while drilling described in the embodiment, the power of the whole measurement while drilling or logging system is optimally managed, the working time of the single downhole measurement while drilling or logging system is prolonged, the usage amount of high-temperature lithium batteries is saved, and the use cost of the measurement while drilling system is reduced. Therefore, the system designed according to the while-drilling power supply management method of the embodiment has the characteristics of stable performance and high reliability, and can effectively save the use of high-temperature lithium batteries. For example, in the case of drilling a deep well with a depth of 5000 meters or more, each time of drilling down and drilling up may take 24 hours or more, and if this time allows the circuitry other than the module for detecting pressure to be in a sleep state, the service life of the battery may be extended by 10% or more.

In a preferred embodiment of the invention, the method for controlling the working state of the measurement while drilling system is optimized.

FIG. 2 is a flow chart illustrating a method for controlling an operation state of a measurement-while-drilling system according to an embodiment of the invention. As shown in fig. 2, the method for controlling the measurement-while-drilling system to be in the working state in the embodiment mainly includes steps 201 to 204.

in step 201, a target operating state of the measurement-while-drilling system is determined.

In step 202, the bottom hole pressure change data corresponding to the target operating condition is looked up in the command knowledge base. The system comprises a measurement-while-drilling system, a command knowledge base and a measurement-while-drilling system, wherein the command knowledge base stores a plurality of working states of the measurement-while-drilling system and bottom hole pressure change data corresponding to each working state one to one.

In step 203, operating parameters of the mud pump are determined based on the bottom hole pressure variation data.

In step 204, the mud pump is controlled to operate according to the operating parameters, so that the measurement while drilling system is in the target operating state.

The present embodiments provide a new method of controlling the operation of a measurement-while-drilling system. That is, the present embodiment provides a method for sending control instructions from the surface to a downhole measurement while drilling system.

Specifically, an instruction knowledge base is constructed offline in advance from the ground, and a plurality of working states of the measurement while drilling system and bottom hole pressure change data corresponding to each working state are stored in the instruction knowledge base. The command knowledge base is preferably pre-consolidated in the pressure sensing microcontroller circuit of the measurement-while-drilling system. Here, the instructions refer to what kind of operating state the measurement-while-drilling system is expected to be in. At the beginning of control, the target working state of the measurement while drilling system is determined according to the system requirements. And then searching bottom hole pressure change data corresponding to the target working state one by one in the instruction knowledge base. Operating parameters of the downhole mud pump are determined from the downhole pressure variation data. In the specific implementation process, a knowledge base storing the corresponding relation between the bottom hole pressure change data and the working parameters of the mud pump can be constructed in an off-line mode, and the working parameters corresponding to the bottom hole pressure change data are obtained by searching the knowledge base. The operation of the mud pump is then controlled in accordance with the operating parameters so that the change in downhole pressure is consistent with the downhole pressure change data determined in step 202.

In the embodiment, the measurement-while-drilling system is controlled to work in the target working state by controlling the downhole mud pump to generate expected downhole pressure change data. For example, in the case of an accident, when the measurement while drilling system does not need to work, and when the drilling is not needed, the surface engineer may adjust the mud pump several times to form a pressure change wave corresponding to a dormant state, so as to transmit a dormant instruction to the downhole measurement while drilling system. It can be seen that the present embodiment forms different downhole pressure variation data by controlling the mud pump, and then uses the downhole pressure variation to make the measurement-while-drilling system in different required working states.

According to the method, a communication line from the ground to the underground and used for specially controlling the measurement while drilling system is not needed, and the measurement while drilling system can be controlled to be in different working states by controlling underground pressure change generated by the current equipment mud pump. The energy saving of the high-temperature lithium battery in this way is also very considerable. In addition, in the working process of the measurement while drilling system, the ground sends an instruction to the underground according to the actual working condition in such a way, so that the underground system (the measurement while drilling system) is in a low-power-consumption energy-saving state, and the service life of a battery is further prolonged. The downhole equipment can also receive other control instructions sent by the surface through the embodiment, for example, the working frequency of the pulser is adjusted, so as to optimize the working state of the downhole drilling tool.

correspondingly, the embodiment of the invention also provides a power management system while drilling.

And the control module 405 is configured to control the operation of the mud pump 406 according to the operating parameters so as to enable the measurement-while-drilling system 304 to be in the target operating state.

In the embodiment, a communication line from the surface to the downhole for specially controlling the measurement-while-drilling system 304 is not required to be configured, and the measurement-while-drilling system 304 can be controlled to be in different working states by controlling the downhole pressure change generated by the current equipment mud pump 406. The energy saving of the high-temperature lithium battery in this way is also very considerable.
