Abstract
The utility model relates to a no-cable type horizontal drilling trace logging instrument which can be connected by an oil rod or a drilling tool and can lift an instrument. The utility model is composed of an underground measuring recorder, a ground and underground time synchronization recording system and a ground playback microcomputer, wherein an underground measuring instrument is provided with an electromagnetic gyro inclinometer; a microcomputer control system of the electromagnetic gyro inclinometer, a charge power supply and a microcomputer program control data acquisition memory system are respectively arranged in the respective instrument rigid bodies, sealed by threading pistons and are connected into integration by sealing soft metal corrugated hoses. The entire measuring process is controlled by microcomputer program so that the accuracy and the automation are high.
Description
The utility model relates to a kind of horizontal drilling track logging instrument, particularly a kind of micro-computer controlled no cable type horizontal drilling track logging instrument.
At present, spectrum is all over the horizontal drilling track logging instrument that adopts both at home and abroad, all adopt cable connection instrument and transmit signal, instrument pushes the shaft bottom by drilling tool inside by fluid pressure, super short radius well system as external use, reach 30cm though measure radius of curvature, track that can not measure water flat drill hole.
This utility model provides a kind of micro-computer controlled no cable type horizontal drilling track logging instrument, and its energy measurement minimum profile curvature radius reaches 3 meters, and can accurately describe the track of lateral aperture, provides orientation and inclination angle, all realize under the surface well micro-computer controlled, the certainty of measurement height.
No cable type horizontal drilling track logging instrument is by down-hole trajectory measurement recorder and ground playback microcomputer, and the time synchronized register system is formed under the surface well, and down-hole trajectory measurement recorder is the core of this instrument.The underground survey recorder is by instrument head 8, electromagnetism gyrolevel 1, inclinometer control system 2, and rechargable power supplies 3,4, micro-computer controlled data acquisition storage system 5, data readback interface 6 is contained in respectively in the instrument rigid body separately.By the threading piston, the flexible corrugated flexible hose 7 of sealing metal connects, and is assembled into one.

Be described in detail the logging instrument course of work below with reference to the accompanying drawings: connect power supply 3 or 4, crystal oscillator 14 produces a time-base signal in the instrument, as the reference signal of time, is consistent the time of downhole instrument and ground degree of depth synchronous recording system.Ground degree of depth synchronous recording system and downhole instrument 24 little time errors were less than 1 second; Two provide micro-computer controlled beat synchronizing signal, make the sampling period 12, and timing controlled 11, multidiameter option switch 17 work synchronous coordination unanimities all under central microprocessor MPU21 unity of command, have the work of beat coordinate synchronization.Instrument gives on function selecting 9 before going into the well and puts sampling density, is 3 or 5 of every meter samplings, starts downhole instrument and ground elapsed time synchronous recording system (being time zero setting) simultaneously on ground, and instrument is transferred to the shaft bottom, proposes measurement on then.
Carry the length (actual is the residing degree of depth of instrument) and the corresponding time of beam hanger or drilling tool on the ground instrument record, downhole instrument is through variable connector 17, cycle detection is gathered accelerometer 18, the X of accelerometer 19 and electromagnetism gyro 20, Y, angular speed information on three directions of Z, amplify and integration output through amplifier 16, deliver to modulus converter A/D 15 and become digital quantity, deliver to central processing unit MPU21, every meter sampling 3-5 group trace information, delivering to memory RAM 22 stores, inclination angle precision ± 0.1 degree, bearing accuracy ± 4 degree, switch 10 is as power supply 3,4 automatic switching control equipment, after one group of supply voltage drops to the regulation lower limit or when breaking down, switch automaticallyes switch, guarantee the long-time operate as normal of instrument, comprise that instrument proposes behind the well head on ground not guarantee in a period of time of playback that data do not lose.
After apparatus measures finishes the proposition well head, with the time of ground instrument record and the time and the corresponding trajectory signal (inclination angle and orientation) of corresponding depth signal and downhole instrument record, be input to ground-based computer, after making the time signal alignment, computer is just handled the trajectory parameters under the same degree of depth of output, carry out colour imaging through color printer, draw horizontal drilling trace graphics with three-dimensional coordinate, depth coordinate is to be the scale of unit with rice, inclination angle and azimuthal coordinates are to be the scale of unit with the degree, have so just finished the logging tasks of one-shot measurement horizontal drilling track.
The utility model has the advantages that with drilling tool or beam hanger to connect and remove instrument, but the horizontal drilling track of 3 meters of continuous measurement radius of curvature, whole process adopts microcomputer program control, and the measuring accuracy height is easy to operate, the automaticity height.
