Description
Technical field
The invention belongs to oil and gas development and Exploration Domain, and in particular to a kind of miniature data conversion storage of contact of underground release
Apparatus and method, for uploading to ground with brill downhole data.
Background technology
The main distinction of well logging and Regular wireline is the real-time of its data acquisition, and formation data is to bore
What well liquid obtained in the case of having slight invasion or no invasion, thus closer undisturbed formation.Complete ground while drilling well
The test of layer data, ground, field assay, explanation are transferred to, have not only saved drilling period, and drilling well can be instructed, adjusted
Wellbore trace is saved, improves drilling course therefore.How the signal in shaft bottom is transferred to the key that ground is logging while drilling technology
Link, while be also one of " bottleneck " for restricting logging while drilling technology development.
Whether well logging at present is divided into wired mode and wireless type according to data transfer.Real-time Transmission mode is by each
The data of measurement while drilling are transferred to ground by the wired or wireless data transfer mode of kind in time.This mode to instructing drilling well,
Particularly drilling well when geosteering have a very important meaning, but various data transfers are all difficult to reach underground at present
Mass data is timely and effectively transferred to ground.
Wire transmission mode includes cable transmission mode, optical fiber transmission means and drill pipe transmission mode.Paper 1 (《Intelligence is bored
The research of column information and electrical power transmission system, oil drilling technology》,2006,34(5):10-13.)：Cable transmits with signal is bored
Method be the tripping in armored cable inside drilling rod, transmission signal.With the intensification of drilling depth, must be proposed when adjunction is single
Cable, or is interspersed in drill pipe bore by cable and with instrument is bored in advance.Paper 2 (《With brill data transfer new technology》.
Oil instrument, 2004,18 (6):26-31.)：Optical fiber transmission means is that the optical fiber with protective layer is lowered into well, from bottom
Ground is connected to instrument is bored.The effect of optical fiber is as cable.Paper 3 (《Rotary steerable drilling state-of-the-art and exhibition
Hope》Petroleum machinery, 2006,34 (4):66-70)：Drill pipe transmission mode is that conductor is arranged in drilling rod to become drilling rod whole
A part for body.Whole drill string is formed electrical signal paths mounted in the special link block of tool joint, realize data transfer.With
These upper modes are due to using wired connection, it is advantageous that transmission speed is very fast, far above wireless mode.But cable,
Optical fiber, drill rod special connector all need to be arranged on whole pit shaft, and during drilling well, drilling rod rotates in high speed, and the above is all easily
Damage.Therefore it is relative complex to there is the shortcomings that common poor reliability, manufacture craft more in these prior arts, and often influences just
Normal drilling process.The above prior art is in actual well logging production process using less.
Wireless transmission method includes three kinds of mud (i.e. drilling fluid) pulse, electromagnetic wave and sound wave.Wherein mud-pulse and electricity
Magnetic wave mode has been applied to actual well logging production, most widely used with mud-pulse formula.Patent 1 (《One kind be used for
Bore the high-speed transmission sending device of measurement》, publication number:201020298582.3)：Mud pulse signal generator is mainly by aerial drainage
Valve or choke valve are formed, and when valve on and off, change is produced by the drilling well flow velocity that annular space is flowed in drill string
Change, the drilling hydraulic Reeb in drilling rod will be caused to produce a series of pulse, data are loaded by opening and closing valve
Onto these pulses, it is possible to data transfer to ground.But mud wave is equivalent to mechanical wave, its modulation system make its speed by
To considerable restraint, the highest transmission speed that technology is reported at present also can only achieve the data of tens per second, it is difficult to meet underground
The quick upload of measurement data.Patent 2 (《The electromagnetic wave signal transmission method and system of a kind of measurement while drilling》, publication number:
102251769A):Electromagnetic measurement while drilling is transmission medium or using drill string as transmission conductor using stratum.Downhole instrument is by measurement
Data are modulated on electromagnetic wave carrier, are launched by electromagnetic wave transmitter in underground, through living various channel transfers to ground.
The electromagnetic wave signal for having modulated measurement data that surface geophone will detect, measurement data is demodulated by process circuit
Come.Document 3 (《Application of the sonic transmissions measuring technology in oil field》Observation and control technology, 2005,24 (11):76278)：It is to utilize sound
Ripple or seismic wave carry out transmission signal by drilling rod or stratum.Sound wave emission system is arranged on drilling rod, and system is by various measurement numbers
According to being modulated on acoustic vibration signal, along drill pipe transmission to ground, the acoustic receiver system for being installed in ground is received, demodulated
Come.Sonic transmissions are as electromagnetic transmission, it is not necessary to which mud circulates, and implementation method is simple, cost is low.And its shortcoming is decay
It is too fast, it is affected by environment very big, low intensity signal caused by well and sound wave and Electromagnetic Interference as caused by drilling equipment, make
Detectable signal is extremely difficult, and transmission speed is slower.Patent 3 (《A kind of release type is with data uploading method under drilling well and system》,
Publication number：201310191269.8) as shown in Figure 1, it is proposed that a kind of by way of depositing microstorage on drill collar, bag
Include:Micro radio transceiver module 10, ground receiving wastewater facility 12, derrick 20, rig 30, drilling rod 40, drill bit 50, hydrophthalmia 51, drill string
Fluid passage 60, with throwing instrument 62, measurement while drilling instrument 65, well 70 and annular space 80 is bored, read-write system passes through in drill collar
Then the data conversion storage of measurement while drilling to microstorage is periodically or non-periodically discharged microstorage, microstorage by wireless mode
Entering annular space follows mud to return to ground, and data are also taken back ground.Because the particular surroundings of underground, size limitation, drill collar are all
Using metal material, the data transmission efficiency of the data conversion storage mode of wireless mode is had a greatly reduced quality.
