Description
Technical field
The utility model relates to a kind of sound wave measurement while drilling pipe nipple, belongs to oil, gas drilling technical field.
Background technology
At present, because the geological conditions that oil drilling production faces and natural environment are more and more severe, therefore the precision of oil/gas drilling is had higher requirement with the hit rate that brill reaches oil-gas reservoir, and the Obtaining Accurate of oil/gas drilling down-hole information and high-speed transfer improve the key of drilling well precision just.The transmission of down-hole information divides wire transmission and wireless transmission dual mode, though wire transmission technology can obtain higher message transmission rate, exists device structure to connect the shortcomings such as complicated and high cost, is difficult for large-scale promotion application.The method of Radio Transmission Technology mainly contains mud-pulse, electromagnetic wave side's harmony wave method, mud-pulse is present topmost communication mode, but its message transmission rate is slow (generally about 5b/s), data transmission capacity is low, signal transmission easily is disturbed, be difficult to realize nearly drill bit measurement, can not be used for underbalance well and air drilling, can not satisfy modernized drilling well to the requirement of signal transmission.Electromagnetic wave is to utilize the electromagnetic wave of extremely low frequency to carry out the signal transmission, because the impact of transmission range and earth-loss, its transmission speed and quality are also very limited, can only carry out the shallow well operation.
The acoustic signals transmission is to utilize sound wave to transfer to the Radio Transmission Technology on ground as the communication carrier, down-hole information, ground signal also can be sent to the down-hole by it simultaneously, realizing the two-way communication of ground and down-hole, is a kind ofly to be expected to obtain more high transfer rate, to be subjected to extraneous factor to affect less transmission technology.If realize this goal, well-designed underground signal transmission system is crucial, and one reasonable in design, processing is superior and the pipe nipple structure is measured in assembling accurately and its prerequisite and basis will have exactly.
Summary of the invention
The purpose of this utility model is to provide a kind of sound wave measurement while drilling pipe nipple, and it can realize the measurement of downhole parameters, guarantees that survey data uploads in real time, for the Real-Time Evaluation on stratum provides reliable downhole drill supplemental characteristic.
Concrete technical scheme of the present utility model is as follows:
The core cylinder of sound wave measurement while drilling pipe nipple is connected in the body centre bore, is provided with sealing ring between core cylinder upper and lower end and body.Core drum outer wall boss and inner body wall boss consist of annular space between the two, core drum outer wall convex shoulder is separated into overhead cabin and lower empty cabin with this annular space, be provided with the acoustic wave transducer group in the overhead cabin, be provided with sensor group, down-hole computer module and power pack from top to bottom in the lower empty cabin.
The utility model sound wave directly is added in the drill bit back in use, can in time feed back hole deviation and azimuthal measurement data, judge the position of drill bit in reservoir, improve the brill encountering rate of reservoir, improve the control level of well track, make well smooth, for the safety of later stage completion tubular column is lowered to and transforms the wellbore conditions that provides good, thereby the raising well yield has very important effect in thin reservoir-level well development.
Description of drawings
Fig. 1 is sound wave measurement while drilling pipe nipple structural representation.
The specific embodiment
With reference to Fig. 1 embodiment of the present utility model is further specified:
Embodiment:
Sound wave measurement while drilling pipe nipple is comprised of body 1, sealing ring 2, overhead cabin 3, acoustic wave transducer group 4, sensor group 5, lower empty cabin 6, down-hole computer module 7, power pack 8, core cylinder 9 and screw thread 10;
The sound wave measurement while drilling pipe nipple upper end helicoid hydraulic motor that is threaded, the lower end drill bit that is threaded.Power pack 8 adopts high power lithium batteries to provide power supply for downhole data collection and transmission; Sensor group 5 is mainly finished the measurement of downhole parameters, and its digital output signal can directly enter down-hole computer module 7, and its quantity and scale determine according to actual needs; Down-hole computer module 7 will receive signal and change into corresponding data, and carry out the work such as preservation, further conversion, coding, modulation and emission of data; The data-signal that acoustic wave transducer group 4 receives from down-hole computer module 7, generation and emission are with the acoustic signals of modulation intelligence.
The composition of conventional measurement while drilling instrument is drill bit+screw rod+hole deviation and azimuthal measurement instrument+impulse sender, hole deviation and azimuthal measurement instrument apart from drill bit distance more than 10 meters, could feedback signals after drill bit enters 10 meters on stratum, improve basis for estimation for whether entering target zone.This instrument is little for the impact of the guiding of thick reservoir, but for the thin reservoir-level section of thickness less than 3 meters, its navigation information lags behind, and causes easily that to bore encountering rate low, and well is rough, and the later stage completion tubular column is lowered to difficulty and the problem such as yield poorly.And the utility model sound wave measurement while drilling pipe nipple directly is added in the drill bit back, with drill bit apart from 1 meter of less than, than conventional measurement while drilling instrument to the Distance Shortened of drill bit 9 meters, can in time feed back hole deviation and azimuthal measurement data, judge the position of drill bit in reservoir, improve the brill encountering rate of reservoir, improve the control level of well track, make well smooth, for the safety of later stage completion tubular column is lowered to and transforms the wellbore conditions that provides good, thereby the raising well yield has very important effect in thin reservoir-level well development.
