Description
The utility model provides the memory-type magnetic locator of the dark usefulness in oil well non-direct reading test school in a kind of oil field.
At present, in the oil reservoir logging, magnetic locator as well logging depth correction instrument device only is confined to direct-reading well logging, test, because the casing coupling signal that magnetic locator is sensed directly is transferred on the surface recorder, therefore, in direct-reading well logging, test process, the dark kinetic energy in school is no problem, but does not also have the depth correction instrument device at present in high temperature, the non-direct-reading section plane test of conventional memory-type technology, can not judge the instrument setting depth exactly, directly influence test result.
Be to solve deficiency of the prior art and a kind of memory-type magnetic locator is provided at above-mentioned the problems of the prior art the purpose of this utility model, it has solved memory-type and has tested the problem that does not have the depth correction instrument device, it can accurately determine the position of down-hole casing box cupling, form a winding hoop, the degree of depth, supplemental characteristic with various data, play the school and act on deeply.
The utility model is made up of down-hole magnetic locator and ground degree of depth real-time follow-up instrument two parts that with computing machine the two to be coupled together be to realize like this, at first press Fig. 1 and designing requirement, buy material requested and parts from market, down-hole magnetic locator (seeing figure A) is made up of permanent-magnet steel 2, winding coil 3.The pulse signal that magnetic locator is sensed is after the wave filter 4 of circuit part carries out selectable detection, by amplifier 5 amplification of doubling, amplified pulse signal becomes digital signal by A/D converter 6 with the pulse simulation conversion of signals, stores in the middle of the storer 7.At this moment, the data that record in the storer are one group of time, box cupling data.Whether recording mode is to adopt mode of excitation, both when magnetic locator passes through casing coupling, no matter in the sampling time, as long as the pulse signal of sensing is greater than the thresholding of wave filter 4, so, circuit part will start automatically, note this moment, box cupling data in a flash.Because there are not the degree of depth data corresponding, therefore, can not realize storing the dark function in school with box cupling.Have only with ground degree of depth real-time follow-up instrument with could realize after downhole stored formula magnetic locator is connected with computing machine: the identical ground degree of depth real-time follow-up instrument of setting with the down-hole detection instrument of data sampling program, power for respectively ground instrument single-chip microcomputer and photoelectric encoder by direct supply, photoelectric encoder is noted the residing at any time degree of depth of instrument, in the sampling time, note the time by single-chip microcomputer, speed, depth data, after test is finished, the time of the down-hole magnetic locator being sensed by the computing machine playback, the time that box cupling data and ground degree of depth real-time follow-up instrument are noted, the depth data merger is the degree of depth, time, the box cupling data realize the dark purpose in degree of depth school; Figure A is the down-hole magnetic locator in Fig. 1, the required direct current of direct supply 1 supply circuit part among the figure A, permanent-magnet steel 2 is connected wave filter 4 with the magnetic locator that winding coil 3 is formed by lead with circuit part, amplifier 5, A/D converter 6 and storer 7 connect by the wiring board bus.Magnetic locator joins by mouth 8 one ends and storer, and the other end is connected with movable computing machine 15 interfaces.After instrument had been surveyed, computing machine linked to each other with interface, and playback goes out time, the box cupling data in the storer, magnetic locator shell 9 protection down-hole magnetic locators.Ground degree of depth real-time follow-up instrument direct supply 10 is supplied with the required direct current of photoelectric encoders 11, storer 12 among the figure B, storer 7 is connected with photoelectric encoder 11, note the degree of depth of magnetic locator operation in down-hole in sampling time of setting, and the speed of instrument operation between two sampled points.After test was finished, computing machine 15 linked to each other with ground degree of depth real-time follow-up instrument interface 13, and playback goes out the degree of depth, speed, the time data in the storer.
The utility model compared with prior art.Have the position that can accurately determine the down-hole casing box cupling, form a winding hoop, the degree of depth, supplemental characteristic with various data, play the school and act on deeply, it has solved memory-type and has tested the problem that does not have the depth correction instrument device.
Fig. 1 is a memory-type magnetic locator one-piece construction synoptic diagram, and 1 is direct supply among the figure, the 2nd, and permanent-magnet steel, the 3rd, winding coil, the 4th, wave filter, the 5th, amplifier, the 6th, A/D converter, the 7th, storer, the 8th, magnetic locator interface, the 9th, magnetic locator shell, the 10th, ground degree of depth real-time follow-up instrument direct supply, the 11st, photoelectric encoder, the 12nd, ground degree of depth real-time follow-up instrument storer, the 13rd, ground degree of depth real-time follow-up instrument interface, the 14th, ground degree of depth real-time follow-up instrument shell, the 15th, computing machine.
