Abstract
The utility model relates to an antifreezing wellhead manometering device [2.1], which comprises a manometer, a manometer base, a shell and a choke plug. A pressure transmission pipe (8) extended below a frozen layer is connected at one side of the choke plug (6) and an inverted valve (5) is arranged in the shell (4). The antifreezing wellhead manometering device has the advantages of simple structure and broad application range. The utility model can sample the pressure normally when the water in a sleeve and a ring-shaped space of an oil pipe is frozen.
Description
Technical field
The utility model belongs to oil field shaft mouth pressure tester field.
Background technology
At present, the well head pressure tester that extensively adopt in the oil field, be outwards to draw a test pipeline section at the annular space place of well head oil pipe and sleeve pipe, one one end of portion's installation within it has the logical housing of rubber cup, an end and external pressure epiphase, the liquid at the annular space place of oil pipe and sleeve pipe or gaseous tension can be passed to outside tensimeter by rubber cup and inner anti freezing solution, to realize the purpose of pressure measurement, facts have proved, this pressure measurement way is not under the very low environment or effective in temperature, has therefore obtained in the oil field using widely.Its major defect is under the very low environment of temperature, also can freeze around the rubber cup, thereby cause pressure measurement inaccurate.Also having a kind of in addition is that application number is " the anti-freeze pressure meter device " that 91222595 Chinese patent is announced, it is that the stagnant water pipeline section that will transmit pressure is installed in the pipeline, circulating water in the tube road is incubated, realize antifreeze, its shortcoming is, when being full of a lot of gas in the very low and pipeline of temperature, the accuracy of pressure measurement does not still guarantee.
Summary of the invention
The purpose of this utility model is exactly in order to provide a kind of both simple in structure, also normally pressure accurately in the time of freezing at the water in sleeve pipe and the oil pipe annular space again.
The utility model is realized by following proposal.
The antifreeze pressure tester of well head of the present utility model comprises tensimeter, pressure gauge stand, housing and plug, and a side joint of described plug has one to extend to the pressure tube that freezes below the layer, and a ball-and-seat also is housed in the described housing.
The utlity model has following advantage.
1. owing to have one to extend to and freeze the following pressure tube of layer at a side joint of plug, so the also normally pressure accurately when freezing of the water in sleeve pipe and oil pipe annular space.
2. because a ball-and-seat also is housed in housing, the pressure measurement noncongeable oil in the pipeline can outwards not flow out from the pressure gauge stand.
Description of drawings
Fig. 1 is a cut-away view of the present utility model.
Embodiment
The utility model is described in more detail below in conjunction with drawings and Examples.
Consult Fig. 1, during pressure measurement, tensimeter (1) is installed on the pressure gauge stand (2) that is positioned at test pipeline section (3) outside, the housing (4) of a taper is equipped with in the inside of test pipeline section, its side and tensimeter join, the plug (6) that pressure tube joint (7) are equipped with at opposite side and middle part joins, the inside of conical shell, a ball-and-seat (5) of activity back and forth is housed, one end of pressure tube joint (7) with communicate with housing (4), the other end links to each other with pressure tube (8), the other end of pressure tube leads to and freezes below the layer, (9) be oil pipe, (10) are sleeve pipes.During work, when tensimeter (1) installs on the pressure gauge stand (2), ball-and-seat (5) just is opened, the noncongeable oil that housing (4) is interior and pressure tube (8) is interior just can transmit pressure along the direction of arrow in Fig. 1 pipeline, even the liquid in the annular space freezes, pressure in the well also can be passed to tensimeter from the pressure tube of bottom, and accurate pressure measurement does as usual.
Claims (2)
1, the antifreeze pressure tester of a kind of well head, it comprises tensimeter, pressure gauge stand, housing and plug, it is characterized in that, a side joint of plug (6) has one to extend to the pressure tube (8) that freezes below the layer.
2, the antifreeze pressure tester of well head according to claim 1 is characterized in that, a ball-and-seat (5) is housed in the housing (4).
