Description
Technical field:
The utility model relates to a kind of magnetic crack detector and ten eightfeeler casing caliper combination logging devices, belongs to oil reservoir logging downhole instrument device class.
Background technology:
The EMDS-42 type magnetic crack detector of Russian production has been introduced in the oil field in the well logging process at present, this instrument can carry out quality examination by oil pipe in the oil well and sleeve pipe, and can detect multilayer sleeve, the breakage and the distortion situation of diagnosis down-hole string, CJ18-200 type 18 arm calipers can accurately detect oil pipe and casing inner diameter, above-mentioned two kinds of instruments use fashion that certain limitation is arranged, because EMDS-42 type magnetic crack detector is mainly used in measuring well middle sleeve wall thickness and detects down-hole string breakage and distortion situation.CJ18-200 type 18 arm calipers are mainly used in the internal diameter that detects oil pipe and sleeve pipe, but this two quasi-instrument can not combine and log well, not only make troubles and can improve logging cost again outward to construction.
The utility model content:
The utility model purpose is in order to overcome above-mentioned shortcoming, and a kind of magnetic crack detector that provides and ten eightfeeler casing caliper combination logging devices, once go into the well after the combination and can realize the instrument acquisition time, thereby the internal diameter, thickness and the casing deformation data that once obtain sleeve pipe simultaneously can improve the well logging timeliness.
Technical scheme:
For reaching above-mentioned target, the utility model is by the surface power supply measuring system, forms by magnetic crack detector and ten eightfeeler casing calipers that single-core cable connects.Between magnetic crack detector and ten eightfeeler casing calipers, be connected with the Control of Voltage pipe nipple, well temperature power panel and the well temperature of in the Control of Voltage pipe nipple, packing into probe and temperature survey circuit board.
Described Control of Voltage pipe nipple can be controlled the flow direction of surface power supply, and when 〉=80 volts of ground power supply power supplies the time, ten eightfeeler casing calipers can enter duty and measure in the work, and when ground powers 〉=130 volts the time, magnetic crack detector can enter the measurement state again.
During the utility model work, the surface power supply measuring system, power to downhole instrument by single-core cable, this power supply bus is directly given the power supply of magnetic crack detector and CJ-18-200 type 18 arm calipers, control the flow direction of surface power supply by the Control of Voltage time-sharing work, when 〉=80 volts of ground power supplies, by the relay K in the Control of Voltage pipe nipple
1Action makes 18 arm calipers carry out data collection task, when 〉=130 volts of ground power supplies, and relay K
2Action quits work 18 arm calipers.And magnetic crack detector when supply voltage reaches 140 volts, begin the action carry out data acquisition, at last acquired signal is delivered to ground system.
The utility model compared with prior art has distinguishing feature:
Because this device combines EMDS-42 type magnetic crack detector and CJ18-200 type 18 arm calipers and logs well, the acquisition time work of can once going into the well, not only saved the well logging time, can improve the well logging timeliness again, good utilisation logger resource more, the combination of this kind pattern can once be gone into the well and accurately be detected casing inner diameter, accurately measuring unit tube thickness and casing deformation again, situations such as crevice corrosion in addition.This device provides quality data for accurately estimating the sleeve pipe situation, thereby guarantees stable, the volume increase of oil well.
