Description
Technical field: the multistage transmission structure of a kind of down-hole formation parameter measurement while drilling, be used for the detection and the transmission of oil exploration drilling process down-hole formation parameter, relate to detecting and the signal transmission technology field of down-hole formation parameter in the oil exploration drilling with boring.
Background technology: in the oil drilling exploration operation, utilize, reach the purpose that oil gas was crept into, found in optimization with boring the online detection of checkout equipment to downhole drill and formation parameter; At present, mainly contain modes such as mud-pulse and electromagnetic transmission with boring the wireless transmission of checkout equipment to information, the mud-pulse mode can only be used in the drilling well of mud, can not be used for gas drilling, and therefore certain limitation is arranged; The electromagnetic wave mode is used comparatively extensive, existing electromagnetic transmission device is by the downhole parameters checkout gear, aboveground antenna, formations such as aboveground signal processing apparatus, because the downhole parameters checkout gear of prior art is arranged on nearly drill bit place, down-hole, so when the degree of depth of drilling well constantly increases, its transmission range also constantly increases, get on form of electromagnetic wave the downhole parameters that collects near the parameter detection device of drill bit in the down-hole data signal transmission, receive by aboveground reception antenna, after aboveground signal processing means processes, be used for optimizing and creep into, find the purpose of oil gas, its shortcoming is: because the transmission range of electromagnetic wave in the down-hole is limited, according to a large amount of experimental results show that, can only satisfy well depth less than in 2800 meters the oil drilling exploration operation, therefore, along with going deep into of drilling well, the degree of depth of pit shaft also can constantly be deepened, after well depth surpasses 2800 meters, most signal is just fallen by formation absorption, the signal that passes to ground is just imperfect clear, therefore cause the erroneous judgement of situation, finally can not reach and optimize the purpose of creeping into and find oil gas.
Summary of the invention: the purpose of this utility model is the problem that exists at prior art, adopt the mode of the wireless forwarding transmission of multistage relay, enhancing electromagnetic wave signal, designed a kind of multistage transmission structure of down-hole formation parameter measurement while drilling of avoiding data in transmission course, to be attenuated absorption.
The utility model is achieved in that the multistage transmission structure of a kind of down-hole formation parameter measurement while drilling, form by checkout gear and multistage transmission structure, it is characterized in that: described checkout gear comprises hole angle, drift azimuth, downhole temperature, vibration, drilling parameter or geologic parameter tester, multistage transmission structure comprises that the wireless relay that is connected on the drilling tool amplifies transmitter, is connected by drilling rod between checkout gear and the multistage transmission structure;
It can be one that the described wireless relay that is connected on the drilling tool amplifies transmitter, also can be a plurality of;
Described checkout gear is arranged on nearly drill bit place, down-hole;
The spacing that is provided with that described wireless relay amplifies transmitter is to be provided with one every 2000～3000 meters;
Described checkout gear is arranged in the checkout gear short circuit 2;
Checkout gear is connected the nearly drill bit place of down-hole equipment, the drilling tool G.I.H is implemented drilling engineering, when well depth whenever above 2000 meters, just on drilling rod, connect a wireless relay and amplify transmitter, amplify transmitter owing to just on drilling rod, connect a wireless relay every 2000 meters, so, the downhole parameters that passes to ground is exactly complete, clearly, the data processing equipment that is arranged on ground receive the down-hole catch data, just can amplify the checkout gear of transmitter one-level one-levels by a plurality of wireless relay once more and send necessary work order through handling, instruct drill bit to creep into, reach the purpose that oil-gas Layer was crept into and found in optimization towards orientation correctly to the down-hole.
Advantage of the present utility model and beneficial effect are: add a plurality of wireless relay and amplify transmitter in drilling rod, electromagnetic wave is prolonged in the transmission range of down-hole, make in the oil drilling exploration operation, online detection to downhole drill and formation parameter becomes possibility, therefore can optimize the down-hole effectively creeps into, and then reach the shortening drilling period, find the purpose of oil-gas Layer.
