Abstract
The utility model relates to an oil well casing gas recycling device. Wellhead recycle casing gas installed on oil well can prevent an output liquid of the oil well from pouring into the oil well casing. The device comprises a casing connecting line pipe which is provided with a separator inlet valve, a uniflow valve and a casing gas pressure gauge. A separator is connected with the casing connecting line pipe. The separator is provided with a separator outlet valve, a pressure gauge and a release valve. Rise of the return pressure of the oil well can be effectively prevented or the output liquid of the oil well is prevented from pouring into the oil well casing effectively. According to the oil well casing gas recycling device provided by the utility model, the separator is provided with the pressure gauge, and the casing connecting line pipe is provided with the casing gas pressure gauge so that pressure change in the production process of the oil well can be observed at any time so as to take measures immediately to realize continuous directional emission at constant pressure of the casing gas. The device is convenient to connect and can be installed for use and disassembled for future use at any time according to the demand of well condition. The device can be installed or disassembled by one person and is simple to operate, and normal production of the oil well can be ensured.
Description
Technical field
The utility model relates to the recycling equipment of well casing gas, and particularly a kind of well casing gas recycle device is installed in the well head recovery of casing gas of oil well and can prevents that produced liquid in oil well from pouring in down a chimney in the entering oil well casing.
Background technology
The control of well casing gas and recycling are than distinct issues in the oilfield development process; The method that solves this type of problem is at present normally installed a flow process that is connected with the production procedure of oil well in oil well casing gate one side, uses the valve of installing in the middle of the flow process to control sleeve pipe gas and enters the discharge value in the oil well production flow process.Though this method can solve problems such as control and the recycling of well casing gas; But the production difficulty is big, and the operating process difficulty can't in time be observed change value of pressure; Very easily cause Oil Well Back Pressure rising or produced liquid in oil well to pour in down a chimney and get in the oil well casing, had a strong impact on the ordinary production of oil well.
Summary of the invention
The purpose of the utility model is exactly the defective that exists to prior art, provides simple in structure, can significantly improve a kind of well casing gas recycle device that well casing gas is recycled.
The technical scheme of the utility model is: a kind of well casing gas recycle device comprises the sleeve pipe connecting line; Eliminator imported valve, ball-and-seat and sleeve pipe atmospheric pressure table are housed on the sleeve pipe connecting line; Eliminator is connected with the sleeve pipe connecting line, separator outlet valve, pressure meter and atmospheric valve are housed on the eliminator.
The beneficial effect of the utility model is: on the sleeve pipe connecting line, ball-and-seat is housed, can prevents effectively that Oil Well Back Pressure from raising or produced liquid in oil well pours in down a chimney in the entering oil well casing; Be equipped with on the utility model eliminator sleeve pipe atmospheric pressure table is housed on pressure meter, the sleeve pipe connecting line, the pressure that can observe at any time in the oil well production process changes, and in time takes measures, and realizes the continuous level pressure of sleeve pipe gas, directed discharging.As being connected with gas transmission pipeline net work, the sleeve pipe gas that filters through eliminator can directly enter in the gas transmission pipeline net work system.This device is easy to connect, can install and use at any time and dismantles for use according to the hole condition needs.One people just can accomplish installation or removal, and is simple to operate, guaranteed the ordinary production of oil well, has tangible economic benefit.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Below be the embodiment of the utility model; Referring to accompanying drawing; A kind of well casing gas recycle device comprises sleeve pipe connecting line 6, and eliminator imported valve 7, ball-and-seat 8 and sleeve pipe atmospheric pressure table 9 are housed on the sleeve pipe connecting line 6; Eliminator 3 is connected with sleeve pipe connecting line 6, separator outlet valve 2, pressure meter 5 and atmospheric valve 4 are housed on the eliminator 3.Pressure meter 5 is installed on the top shell of eliminator 3, and atmospheric valve 4 is installed on the bottom shell of eliminator 3.Separator outlet valve 2 on the eliminator 3 is connected with oil well gathering line 1, with the thimble connector 10 of sleeve pipe connecting line 6 entrance points and the clamp connection of oil well casing valve.In sleeve pipe gas removal process, when using operation, at first open eliminator imported valve 7, open separator outlet valve 2 again, through the pressure in the pressure meter 5 observation eliminators 3.When pressure reached the spool of jack-up ball-and-seat 8, sleeve pipe gas filtered the back through eliminator 3 and gets in the oil well gathering line 1.Ball-and-seat 8, sleeve pipe atmospheric pressure table 9 are used to prevent that the casing pressure height from causing refluence and monitoring casing pressure to change, and the filtered water in the eliminator 3 are carried out emptying through emptying valve 4, are disposed in the special container and reclaim.Control to reach steady, the lasting discharging of sleeve pipe gas through the automatic unlatching of ball-and-seat 8.
