Abstract
The utility model provides a sleeve pipe gas automatic control device, belong to a device for the oil field production, it has the first connector that is used for connecting the sleeve pipe gas exit tube on the wellhead assembly, install first outer sleeve in the first connector, install confined first inner skleeve in outer end in the first outer sleeve, the intercommunication has manometer and communicating pipe on the first inner skleeve, upper end and the outer end confined second inner skleeve of communicating pipe are linked together, the second inner skleeve is in the same place with the installation of second outer sleeve, the second outer sleeve links together with the second connector that is used for being connected the play oil pipe on the wellhead assembly, second inner skleeve internal fixation has the ball valve seat, there is the valve ball ball valve seat inboard, there is the spring valve ball inboard. This kind of device during the use, when sleeve pipe gas atmospheric pressure is higher than the back pressure of oil recovery, can automatic be opened the valve and discharge sleeve pipe gas in to an oil pipe, and the automatic control of sleeve pipe gas atmospheric pressure has been realized to self -closing valve behind the pressure balance. Sleeve pipe gas no longer emits into the air, has improved the security, has alleviateed environmental pollution.
Description
Technical field
The utility model provides a kind of field produces device, especially a kind of control device of casing gas.
Background technology
In oilfield process, in oil well, casing gas can be produced.If casing gas air pressure is too high can affect pumping efficiency of oil pump, reduce output.The method of current reduction casing gas air pressure is manual operation drain sleeve gas, and casing gas directly enters air.This is contaminated air not only, and there is certain danger, and operator's natural gas can be caused time serious poisoning.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of casing gas self-con-tained unit, and it can control the air pressure of casing gas automatically.
The utility model realizes like this, a kind of casing gas self-con-tained unit, it has the casing gas on connecting well mouth device to go out the first connector of pipe, first outer sleeve is installed in the first connector, the first inner sleeve that outer end is closed is installed in the first outer sleeve, first inner sleeve is communicated with pressure meter and communicating pipe, the second inner sleeve that upper end and the outer end of communicating pipe are closed is connected, second inner sleeve and the second outer sleeve are installed together, second outer sleeve links together with the second connector for being connected the flowline on wellhead assembly, second inner sleeve internal fixtion has ball valve seat, valve ball is had inside ball valve seat, spring is had inside valve ball, valve bonnet is had inside spring.
Telescoping tube is communicated with in the middle part of described communicating pipe.
Adopt the casing gas self-con-tained unit of said structure, during use, when casing gas air pressure is higher than the back pressure of recovering the oil, the automatic Open valve of meeting is to exclusion sleeve gas in flowline, and automatic-closing valve after pressure balance, achieves the automatic control of casing gas air pressure.Casing gas no longer enters air, improves safety, alleviates environment pollution.And save manpower.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model structure.
Detailed description of the invention
The embodiment provided below in conjunction with accompanying drawing further illustrates the concrete structure of utility model.
As shown in drawings, a kind of casing gas self-con-tained unit of the utility model, it has the casing gas on connecting well mouth device to go out the first connector 13 of pipe 12, first outer sleeve 15 is installed in first connector, the first inner sleeve 17 that outer end is closed is installed in the first outer sleeve, first inner sleeve is communicated with pressure meter 16 and communicating pipe 7, the second inner sleeve 5 that upper end and the outer end of communicating pipe are closed is connected, second inner sleeve and the second outer sleeve 3 are installed together, second outer sleeve links together with the second connector 2 for being connected the flowline 1 on wellhead assembly, second inner sleeve internal fixtion has ball valve seat 6, valve ball 8 is had inside ball valve seat, spring 9 is had inside valve ball, valve bonnet 10 is had inside spring.
Casing gas goes out pipe and can to adopt with the connection of the first connector and become joint or be threaded, and flowline can adopt clip with the connection of the second connector or be threaded.
In use procedure, when the atmospheric pressure that casing gas goes out the casing gas flowed out in pipe is higher than the pressure of spring to valve ball, valve ball and ball valve seat depart from, casing gas enters flowline through inner sleeve inner chamber, ball valve seat endoporus, valve bonnet endoporus, valve is opened automatically, gas pressure in sleeve pipe is by pressure release, and air pressure reduces.And the atmospheric pressure of casing gas lower than the pressure of spring to valve ball time, valve ball is pushed to ball valve seat by spring, closure ball valve seat endoporus, and valve is closed automatically.Like this, the automatic control of casing gas air pressure is just achieved.
Telescoping tube 11 is communicated with in the middle part of described communicating pipe 7.Owing to there being the existence of telescoping tube, the distance that the length of communicating pipe can go out between pipe and flowline according to the casing gas on wellhead assembly adjusts.Telescoping tube can adopt screwed pipe etc.
Pressure meter is for showing the pressure of casing gas.
First outer sleeve can have on the first spanner 14, second outer sleeve and can have the second spanner 4.Be convenient to the installation of each outer sleeve like this.
