The tester of the utility model improves the mounting structures of a pressure-sensing element and a temperature-sensing element and the heat receiving mode of the temperature-sensing element. The tester of the utility model can be used for simultaneously testing the distribution of the downhole pressure and the temperature of each downhole horizon of the oil well in once testing work, simplifying the testing process; the utility model has the advantages of high precision and low cost, reduces the temperature-sensing time of the instrument, and reduces the length of the instrument; the utility model is suitable for the double-parameter test of the downhole pressure and the temperature of the oil well in various operating conditions.
Description
The utility model is a kind of pressure and temperature biparameter tester that is used for the oil exploitation well.
Usually, oil well down-hole pressure and temperature test are to adopt the test of going into the well at twice of pressure tester and temperature measuring device respectively.There is following shortcoming in this test technology: 1. pressure and temperature test data contrast property poor (steamed well is tested more so); 2. must twice test jobs, expense height, efficient are low.Domestic have a kind of " measuring the measuring instrument of temperature and pressure simultaneously " (patent announcement number: CN2039740U), it be the down-hole heat dynamically (temperature and pressure) that is used to measure steam huff puff production wells.This measuring instrument can be in one-stop operation the variation of each layer position saturated-steam temperature and pressure under the measuring well simultaneously, measuring process is simplified, and can obtain the mutual corresponding survey data of temperature and pressure.But there is following shortcoming in this measuring instrument:
1. on structure design
A. pressure record power transmission shaft and thermograph power transmission shaft support mutually, and both rub each other, influence the data testing accuracy of temperature and pressure;
B. the TEMP part links with the polyphone form with the pressure sensing part, and instrument is long, and (1800mm, spring-tube type well pressure measuring instrument length commonly used is 1225 1425mm.The long 780mm of SW-150 type downhole temperature tester commonly used).
2. being subjected on the hot mode at temperature-sensing element
The measured medium temperature is passed to temperature-sensing element with the heat radiation heat transfer type again through tool housing, makes the temperature-sensitive time lengthening of temperature-sensing element.
The purpose of this utility model is to overcome the shortcoming of above-mentioned tester, provide a kind of hot mode that is subjected to that improves instrument mounting structure and temperature-sensing element, with down-hole pressure and the temperature biparameter tester that is used for oil exploitation well (comprising steam huff puff production wells).
The technical scheme that the utility model is taked is:
1. temperature-sensing element (8) is sleeved in the inner chamber of pressure sensor (7), thereby shortens tool length;
2. pressure record penholder (5) is a hollow shaft, and thermograph penholder (3) passes wherein, is independent of each other to guarantee both to rotate simultaneously;
3. spring bearing (4) is housed on tool housing (6),, thereby eliminates mutual friction mutually between pressure record penholder (5) and the thermograph penholder (3), the data testing accuracy of raising instrument with abutment pressure pen arm (5);
4. the heat-conducting medium (9) of in the ring cavity of tool housing (6) and temperature-sensing element (8), packing into, make temperature-sensing element (8) conducted heat by heat radiation by hot mode to change the conduction heat transfer mode into, thereby reduce the temperature-sensitive time of temperature-sensing element (8).This test for the downhole temperature section is particularly important.
The utility model can be simplified test step, improves the data testing accuracy of instrument, reduces the temperature-sensitive time of instrument, shortens tool length, the lowering apparatus cost.
The utility model will be further described below in conjunction with accompanying drawing.
Accompanying drawing is the structure chart of down-hole pressure and temperature biparameter tester.
The utility model is made up of nine component and a kind of heat-conducting medium: thermograph nib (1), pressure record nib (2), thermograph penholder (3), spring bearing (4), pressure record penholder (5), tool housing (6), pressure sensor (7), temperature-sensing element (8), pressure transmission capillary tube (10), heat-conducting medium (9).
Temperature-sensing element of the present utility model (8) is sleeved in the inner chamber of pressure sensor (7).Pressure record penholder (5) is a hollow shaft, and thermograph penholder (3) passes wherein, and both can rotate simultaneously, are independent of each other.Thermograph penholder (3) is welded on the free end of temperature-sensing element (8), and thermograph nib (1) is screwed on thermograph penholder (3).Spring bearing (4) is housed on the tool housing (6).The lower end of pressure record penholder (5) is welded on the free end of pressure sensor (7), and the upper end is supported by spring bearing (4), to eliminate the phase mutual friction between pressure record penholder (5) and the thermograph penholder (3).For guaranteeing that pressure record penholder (5) can rotate flexibly, spring bearing (4) can adopt single-row radial ball bearing.Pressure record nib (2) is screwed on pressure record penholder (5).In the ring cavity of tool housing (6) and temperature-sensing element (8), heat-conducting medium (9) is housed, to reduce the temperature-sensitive time of temperature-sensing element (8).Adopt machine oil to make heat-conducting medium to conventional producing well test, test adopts silicone oil to make heat-conducting medium to steam huff puff production wells.
The utility model is in when test, with common steel wire erecting by overhang with the instrument G.I.H.Measured medium pressure imports pressure sensor (7) into through pressure transmission capillary tube (10).The upper end of pressure sensor (7) is a free end, the lower end is a fixed end, behind its inner pressurized, free end just correspondingly rotates to an angle, and the pressure record penholder (5) that drive is fixed on the free end rotates together, the pressure record nib (2) that is fixed on the pressure record penholder (5) just is recorded in its movement locus on the recording card (among the figure draw in the end), and this track has reflected the size of measured medium pressure; Simultaneously, the measured medium temperature acts on temperature-sensing element (8) through tool housing (6) and heat-conducting medium (9) in the conduction heat transfer mode.The lower end of temperature-sensing element (8) is a fixed end, and the upper end is a free end.Because temperature-sensing element (8) is the helix tube that is made by two kinds of different sheet metals of coefficient of thermal expansion, when variations in temperature, its free end just correspondingly rotates a certain angle, and the thermograph penholder (3) that drive is fixed on its free end rotates together, the thermograph nib (1) that is fixed on the thermograph penholder (3) just is recorded in its movement locus on same the recording card (among the figure draw in the end), and this track has reflected the size of measured medium temperature.Because pressure record penholder (5) is a hollow shaft, thermograph penholder (3) passes wherein, and both can rotate simultaneously, are independent of each other.Along with instrument along the moving of course of the hole, the distribution of down-hole pressure and temperature goes on record simultaneously.
