Abstract
A jamming type valve manometer mainly solves the problems in the prior instrument for mesuring the static pressure which can not really reflect the ground pressure change, characterized in that, a ball seat (3) is fixed in a main body (1), a friction ball is arranged on the upper part of the ball seat (3), and a liquid outlet (6) is arranged on the lateral wall of the main body (1) over the ball seat (3). The jamming type valve manometer can replace the packer to put into the deflection hole, detect the pressure of the liquid outlet when in normal water injection, and after the completely shutting down the well stably, not only the pressure falling curve is got, but also the change of the ground static pressure is tested correctly, which effectively ensures the reality and the reliability to test the data.
Description
Technical field:
The utility model relates to down-hole formation pressure test used a kind of instrument, especially blocking type valve pressure gauge in the oil-field flooding field.
Background technology:
Blocking type valve pressure gauge is that a kind of instrument of pressure down-hole blanking plug outlet pressure and stratum is recovered when being used for testing water filling in the oil field.The instrument that pressure is recovered on existing measurement stratum generally all is to be lowered to pressure gauge again after pulling the blanking plug of each layer earlier out, can cause the fluctuation of water injection pressure like this, the test effect in influence early stage, the pressure of blanking plug outlet when also gathering less than water filling.Because the test data actual response variation that goes out strata pressure comprehensively, what make the oil field geologic geological scheme determines to lack perfect scientific basis.
The utility model content:
For the instrument test data that overcome existing measurement static pressure can not go out the deficiency that strata pressure changes by actual response, the utility model provides a kind of blocking type valve pressure gauge, this blocking type valve pressure gauge can replace the inclined to one side hole of blanking plug input under the situation of normal water filling, do not influence the water injection well normal operation, and can obtain the outlet pressure of blanking plug; After treating that the complete shut-down well is stable, can accurately test out the variation that strata pressure recovers, guarantee the authenticity and the reliability of test data.
The technical solution of the utility model is: this blocking type valve pressure gauge comprises main body, on the sidewall of main body pressure sensor is installed, pressure sensor links to each other with data storage, the lower end of main body has inlet, be fixed with ball seat in the main body, the ball seat top is equipped with steel ball, and the main body wall of ball seat top has liquid outlet.
The utlity model has following beneficial effect: owing to take the steel ball of the top of ball seat in the such scheme ball seat can be opened and shutoff, solved to utilize a pressure sensor once to go into the well just can to measure blanking plug outlet pressure and strata pressure and recovered problem.This is that prior art can not realize.This method can obtain the true curve that closing well front and back pressure changes, and the data that record are accurate, reliable, for the oil field provides genuine and believable science data; The utility model replaces the inclined to one side hole of blanking plug input under the situation of normal water filling, do not influence the water injection well operate as normal.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-main body among the figure, 2-inlet, 3-ball seat, 4-steel ball, 5-pressure sensor, 6-liquid outlet.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this blocking type valve pressure gauge comprises main body 1, pressure sensor 5 is installed on the sidewall of main body 1, pressure sensor 5 links to each other with data storage, the lower end of main body 1 has inlet 2, be fixed with ball seat 3 in the main body 1, ball seat 3 tops are equipped with steel ball 4, and main body 1 sidewall of ball seat 3 tops has liquid outlet 6.
During actual the use, liquid enters from inlet 2 in the oil pipe, and behind the closing well, steel ball 4 drops on the sealed ball seat 3, the curve of the falling strata pressure of pressure sensor 5 after liquid outlet 6 tests out reliable closing well and stratum, stable back static pressure.Under the situation of water injection well operate as normal, pressure gauge is dropped into accurately and be positioned in the inclined to one side hole of target interval injection well downhole flow regulator, this moment, fluid pressure in oil pipe entered pressure gauge from inlet 2, fluid pressure causes steel ball 4 to break away from ball seat 3 in the oil pipe, then the oil pipe internal pressure acts on the pressure sensor 5 by ball seat 3 and liquid outlet 6, stablizing in a period of time, this moment, pressure curve was stable.When closing well, fluid pressure descends in the oil pipe, and pressure curve falls after rise, tell because strata pressure is counter, and the steel ball 4 return of serve seat 3 that falls, with ball seat 3 sealings, tubing pressure and strata pressure separation.Recovery along with strata pressure, pressure curve tends towards stability, pressure acts on the pressure sensor 5, by data storage the signal of pressure sensor 5 is carried out acquisition process and storage, take out behind the EOT pressure gauge with data readback to computer, data analyzed and explained by computer software.The utility model volume is little, and is easy to use, can throw in into replacing blanking plug to use in the inclined to one side hole of injection well downhole flow regulator, guaranteed the reliability of test; This utility model can drop into downhole testing under normal water filling situation, can obtain the true curve that closing well front and back pressure changes, can record the static pressure after pressure falls after rise behind the flowing pressure of normal water filling and the closing well, the data that record are accurate, reliable, for the oil field provides genuine and believable science data.
