Description
Technical field:
The present invention relates to a kind of high-temperature and high-pressure small-size length, belong to the displacement sensor technical field.
Background technology:
In oilfield exploitation procedure, because shale expansion causes bit freezing, because receiving the place, cement causes seepage during well cementation during drilling well, these all are great industrial accidents.For fear of the generation of these industrial accidents, generally all want to do in the laboratory earlier the in-site modeling test.Though the instrument that can do experiment in the laboratory is a lot, but under same instrument, the same temperature, pressure, to detect the data error made from a kind of specimen very big, do not have repeatability,, make a big impact to research and production because the data error that instrument is made does not have confidence level.Cause the subject matter of data error just to be sensor, the sensor that uses has contactless and two kinds of universal sensors of contact at present, the method of measuring also is multifarious, but under high-temperature and high-pressure conditions, because temperature and pressure is to the influence of sensor, the electronic component of sensor can produce very big temperature and wafts when temperature was spent from room temperature～200; Add and make some element modification of sensor under the high-pressure situations, in positive and negative 2 millimeter, in this case then can't work substantially by the sensor that has for the data error of output.Therefore,, under above-mentioned high-temperature and high-pressure conditions, all can't satisfy its requirement, also can mislead the drilling well and the cementing design scheme in oil field no matter be contactless or the universal sensor of contact.
Summary of the invention:
The objective of the invention is to, provide a kind of and be made of high temperature magnet, sensor and dial gauge, integrate electromechanics and measure, can accurately measure under high-temperature and high-pressure conditions, safe and convenient to use, test data is high-temperature and high-pressure small-size length accurately and reliably.
The present invention realizes above-mentioned purpose by the following technical solutions:
A kind of high-temperature and high-pressure small-size length, it is made of sensor, dial gauge, dial gauge support, overcoat, movable sleeve, device body, high temperature magnet and sounding rod, it is characterized in that: be equipped with in the center pit of device body by the fixing sounding rod of the gland nut of lower end, the upper end of sounding rod is fixed with a high temperature magnet by gland nut; Device body is set with movable sleeve outward, be equipped with on the inwall of movable sleeve with sounding rod on the corresponding high temperature magnet of high temperature magnet, the outside of movable sleeve is set with overcoat, puts outward to have chute, the slide block on the movable sleeve passes chute; Sensor is equipped with at the top of overcoat, and the middle part of overcoat is fixed with a dial gauge by the dial gauge support, and the gauge outfit of dial gauge places on the slide block.
The present invention's beneficial effect compared with prior art is:
This high-temperature and high-pressure small-size length adopts a high temperature magnet is connected on the sounding rod, another high temperature magnet is connected on the movable sleeve, sounding rod is contained in the device body of anti-high pressure, when sounding rod is up and down, high temperature magnet on the outer movable sleeve of high temperature magnet on the sounding rod and device body is up and down synchronously, because the high temperature strong magnet does not demagnetize under hot conditions, has guaranteed the dynamic role and the reliability of this device under the high-temperature and high-pressure conditions.In addition, because sensor is installed in this device top, can produce temperature and waft; And electromechanical measures with sensor and dial gauge simultaneously to testee, and comparative is arranged; Solved the problem of measuring accuracy under the high-temperature and high-pressure conditions, also guaranteed the test data accuracy simultaneously, reliable basis is provided for the drilling well and the cementing design scheme in oil field.
Description of drawings:
Accompanying drawing is the structural representation of high-temperature and high-pressure small-size length.
Among the figure: 1, sensor, 2, dial gauge, 3, the dial gauge support, 4, overcoat, 5, housing screw, 6, movable sleeve, 7, device body, 8,10, high temperature magnet, 9,11, gland nut, 12, sounding rod, 13, chute, 14, slide block.
Embodiment:
This high-temperature and high-pressure small-size length is made of sensor 1, dial gauge 2, dial gauge support 3, overcoat 4, housing screw 5, movable sleeve 6, device body 7, high temperature magnet 8,10, gland nut 9,11 and sounding rod 12.Sounding rod 12 is housed in the center pit of device body 7, and sounding rod 12 is fixing by the gland nut 11 of the center pit lower end of device body 7, and the upper end of sounding rod 12 is fixed with a high temperature magnet 10 by gland nut 9.The device body 7 outer movable sleeves 6 that are set with, be equipped with on the inwall of movable sleeve 6 with sounding rod 12 on high temperature magnet 10 corresponding high temperature magnet 8, high temperature magnet 10 is corresponding with the installation site of high temperature magnet 8, the outside of movable sleeve 6 is set with overcoat 4, one side of overcoat 4 has chute 13, and the slide block 14 on the movable sleeve 6 passes chute 13; Sensor 1 is equipped with at the top of overcoat 4, and the middle part of overcoat 4 is fixed with a dial gauge 2 by dial gauge support 3, and the table bar of dial gauge 2 places (referring to accompanying drawing) on the slide block 14.
This high-temperature and high-pressure small-size length principle of work is as follows: sounding rod 12 can slide up and down in the center pit of the device body 7 of anti-high pressure, be subjected to the promotion of testee when sounding rod 12, when up and down, the high temperature magnet 10 that drives on it moves up and down in device body 7; 10 of high temperature magnet, slide up and down with sounding rod 12 and drive movable sleeve 6 outer high temperature magnet 8 effects of device body 7 synchronously by magnetic force, and the top of movable sleeve 6 drives sensor 1 and carries out displacement measurement.On the other hand, the slide block 14 on the movable sleeve 6 also slides up and down in the chute 13 of overcoat 4 synchronously, and 14 gauge outfits that drive dial gauge 2 of slide block are carried out displacement measurement simultaneously.This device adopts mechanical, electrical integrated testee is measured with sensor 1 and dial gauge 2 simultaneously, has comparative; Because sensor 1 is at the top of this device, sensor 1 is not influenced by the high-temperature and high-pressure conditions of testee, can not produce temperature and waft; Solved under high-temperature and high-pressure conditions, owing to the influence of temperature and pressure to sensor, the electronic component of sensor can produce very big temperature and waft, the inaccurate problem of measuring accuracy.
