Abstract
The utility model relates to a superhigh-pressure manometer without water and oil immersion when fractured by high-energy gas, mainly composed of a press cover, a sleeve body, a piston rod pole, a copper cylinder, etc., wherein, an O-shaped sealing ring is arranged between the press cover and the sleeve body; the lower part of the piston rod pole positioned in a pressure measuring chamber is provided with two O-shaped sealing rings; both sides of the upper part of the press cover are provided with two planes. The utility model has the advantages of reasonable sealing mechanism and good sealing performance; when the utility model is impacted by superhigh-pressure gas, water and oil can not enter the pressure measuring chamber to guarantee the accuracy of the measured pressure.
Description
The utility model relate to a kind of in the high energy gas fracture process, be used for testing along the high-pressure water oil of the pressure of pit shaft direction each point do not immerse manograph.
At present mostly using cannon gun pressure manograph when high energy gas fracture measures along the force value of pit shaft direction each point.This cannon gun pressure manograph, because no packoff, in underground oil-water under the effect of UHV (ultra-high voltage), cause profit to enter the pressure measuring cavity of manograph and influence vertical compression of copper cylinder, make the force value distortion that records, the reasonable use of the dose when this force value distortion will directly influence high energy gas fracture, the correct adjustment of powder charge mechanism and the selection on stratum.
For overcoming the shortcoming of above-mentioned manograph, the utility model provides a kind of novel high-pressure water oil not immerse manograph.The utlity model has rational sealing mechanism, profit 100% does not immerse under the UHV (ultra-high voltage) effect in oil well, thereby reaches the purpose of accurate pressure measurement.
The utility model is achieved in that this high-pressure water oil does not immerse manograph, mainly constitute by gland, sleeve body, piston roofbolt and oil pressure copper post, have together between gland and the union body and go up " O " RunddichtringO, " O " RunddichtringO under the twice is arranged at the piston roofbolt bottom that is positioned at pressure measuring cavity; There are two planes on its both sides, gland top.
Accompanying drawing 1 is the structural representation that high-pressure water oil does not immerse manograph.
Describe principle of work of the present utility model and specific implementation process in detail below in conjunction with accompanying drawing:
The utility model mainly is made of " O " RunddichtringO 5 and copper cylinder 6 under gland 1, last " O " RunddichtringO 2, sleeve body 3, piston roofbolt 4, the twice.As shown in drawings, gland 1 lower end of the utility model top has screw thread can be spun on the sleeve body 3, and gland 1 upper end not only middle part has a groove but also both sides to be milled with the plane, is convenient to installation and removal.Between gland 1 and sleeve body 3, be equipped with together and go up " O " RunddichtringO 2, the bottom that is contained in the piston roofbolt 4 in the sleeve body 3 has the twice groove to be used to install " O " RunddichtringO 5 under the twice, piston roofbolt 4 and sleeve body 3 constitute a pressure measuring cavity, and copper cylinder 6 is contained in the pressure measuring cavity.During the high energy gas fracture construction, the utility model is lowered in the oil well together in company with the high energy gas fracture instrument, together arrives assigned address with the high energy gas fracture instrument.Under the percussive action of the high temperature and high pressure gas that produces in the high energy gas fracture process, make 4 longitudinal sliding motions of piston roofbolt, the copper cylinder 6 in the last sliding piston roofbolt 4 extruding pressure measuring cavities makes copper cylinder 6 produce vertical compression deformation.High energy gas fracture construction will the utility model proposes outside the oil well after finishing, and unload lower cover 1, take out copper cylinder 6, measure the size of the copper cylinder 6 after the distortion with milscale, look into this copper column pressure table of comparisons again, can read the force value that institute's location is put.If survey the force value of multiple spot position, can put into a plurality of high-pressure water oil simultaneously and not immerse manograph and get final product.
Advantage of the present utility model: 1. the utility model sealing mechanism is reasonable, and under the impact of super-pressure, oil, water all can not enter pressure measuring cavity, have guaranteed the accuracy of institute's measuring pressure in oil well. 2. the gland of cannon thorax manograph is sunk screw, and installation and removal are all inconvenient, and service life is short, outside the gland 1 outstanding sleeve body 3 of the present utility model, mounts and dismounts all very convenient. 3. the utility model saves one deck copper sheet that the sleeve body outsourcing of former cannon thorax manograph, so that the utility model handling ease, cost. 4. the utility model can multistagely use.
Claims (2)
1, a kind of high-pressure water oil does not immerse manograph, mainly constitute by gland (1), sleeve body (3), piston roofbolt (4) and oil pressure copper post (6), it is characterized in that: have between gland (1) and the union body (3) and go up " O " RunddichtringO (2) together, " O " RunddichtringO (5) under the twice is arranged at piston roofbolt (4) bottom that is positioned at pressure measuring cavity.
2, high-pressure water oil according to claim 1 does not immerse manograph, it is characterized in that there are two planes on its gland (1) both sides, top.
