The utility model relates to equipment of measuring boreholes or wells. A combination well logging device consists of an electrode part and an instrument part, the electrode part and the instrument part are connected with each other, wherein the instrument part consists of a bridle, a spontaneous gammar well logger, a well deviation direction well logger, an electronic circuit pipe nipple and a push type combination instrument. The combination well logging device achieves combination of various instruments. When the combination well logging device descends in the well, the combination well logging device is capable of completely fetching altogether nine curves including a 4 m bottom gradient, a 2.5 m bottom gradient, a self-potential, a hole diameter, a micro-gradient, spontaneous gammar, obliquity and direction. All data, including the series of the nine curves, sound wave and an induction log curve, needed by a common completion well is completely fetched. The equipment of measuring the boreholes or the wells has the advantages of not only ensuring accuracy of data collection, but also improving well logging aging, reducing probability of occurrence of well logging engineering accidents and greatly improving well logging aging.
Description
Technical field
The utility model relates to a kind of equipment of measuring boring or well.
Background technology
For many years, the microelectrode system in each oil field and electrode system well logging are following the mode of going into the well for 1 time and repeatedly measuring, and can not go into the well for 1 time and get full electrode system, microelectrode, hole diameter and natural potential data.Generally speaking, need to carry out respectively 4 m bottom gradient, microelectrode, 2.5 m bottom gradient+natural potential+3 times well loggings of hole diameter.This has not only strengthened well logging amount and difficulty of construction, also has simultaneously larger engineering risk.In addition, because the power supply of well logging and signal are processed all on ground, it is many to take cable core, can not measure simultaneously, more can't with other instrument combination.
Summary of the invention
The utility model aims to provide a kind of combination logging device of going into the well and can record many curves for 1 time.
Combination logging device described in the utility model partly forms by interconnecting electrode part and instrument, and its Instrumental part is comprised of the head harness that links to each other successively, natural gamma logging device, drift azimuth logging instrument, electronic cartridge and pushing type combination instrument.
Preferably, the electrode part is provided with 6 electrode retaining collars.
Perhaps more preferably, electronic cartridge is by power supply and measuring circuit, electrode system gear shift calibration circuit, microelectrode power supply and measuring circuit, microelectrode gear shift calibration circuit and the caliper logging the electric circuit constitute of power circuit, electrode system.
The utility model combination logging device has been realized the combination of multiple instrument, 1 desirable complete 4 m bottom gradient, 2.5 m bottom gradient, natural potential, hole diameter, micronormal, microinverse, natural gamma, inclination angle and orientation totally 9 curve of going into the well.9 same sound waves of curve that this series gathers, induction logging curves have been got entirely 1 mouthful of needed whole data of common productive completion together.It had both guaranteed the precision of data acquisition, had improved again the well logging timeliness, had also reduced Well Logging Engineering accident odds, had greatly improved well logging construction timeliness.
Description of drawings
Fig. 1 is the structural representation of embodiment one.
The specific embodiment
Embodiment one.
The combination logging device partly forms by interconnecting electrode part and instrument, and its Instrumental part is comprised of the head harness 1 that links to each other successively, natural gamma logging device 2, drift azimuth logging instrument 3, electronic cartridge 4 and pushing type combination instrument 5.The electrode part is provided with 6 electrode retaining collars.Electronic cartridge 4 is by power supply and measuring circuit, electrode system gear shift calibration circuit, microelectrode power supply and measuring circuit, microelectrode gear shift calibration circuit and the caliper logging the electric circuit constitute of power circuit, electrode system.
After instrument is started working, confess the square-wave signal of current constant to the stratum by electrode system emission electrode ring A, torpedo is current supply circuit.2.5m bottom gradiometry electrode retaining collar M
2.5, N
2.5On signal send into combination logging tool after, through differential amplification, detection filter, output represent the d. c. voltage signal of gradient resistance rate bottom 2.5 m.In like manner, 4 m bottom gradiometry electrode retaining collar M
4, N
4On signal obtain after treatment representing the d. c. voltage signal of 4 m bottom gradient resistance rate.In addition, the electronic circuit part provides another constant current square wave to the microelectrode pole plate of backup part, and current supply circuit is tool housing.After processing, the voltage difference of getting 2 measurement electrode on the pole plate obtains the microinverse signal, gradiometry electrode retaining collar M bottom the 2.5m in the 2nd measurement electrode and the electrode system on the pole plate
2.5Voltage difference can obtain the micronormal signal after treatment.These 4 d. c. voltage signals directly enter the analog signal measuring channels of drift azimuth logging instrument 3.In drift azimuth logging instrument 3, be uploaded to ground after the impulse form natural gamma signal of these signals and inclination angle, bearing signal and natural gamma logging device 2 inputs is encoded.In ground system, these signals just obtain corresponding apparent resistivity curve and inclination angle, orientation and gamma ray curve after treatment.From the above analysis, for carrying out the electrode system well logging, natural gamma logging device 2 and drift azimuth logging instrument 3 will provide 5 through tracks as the connecting line of described combination logging device to the respective electrical polar ring at least.
The measurement of hole diameter is finished separately by the combination logging device.Well radius variations is produced voltage signal input hole diameter measuring circuit, and the signal after the amplification is transferred to ground by power transformer centre cap and cable sheath with analog signal form.Self-potential survey ring SP receives ground by cable core 7, obtains the natural potential signal on ground.Therefore, the combination logging device can provide the signal of 7 digital forms and the signal of 2 analog forms simultaneously earthward.Use this combination can make ground logging system record simultaneously 9 logs for 1 time.
