Abstract
The utility model relates to an oil-well-head associated gas recovering-valve, which can solve the problem that the associated gas can not be recovered. The utility model is characterized in that: a valve body (10) is connected vertically with a short session (8), the inner side of the valve body (10) is fixed with a cone valve core (9) through a bond (14), and the cone surface of the valve core (9) is arranged in mutual touch at the right end head of a three-way (7) in a connecting body (6); the inner side of the valve core (9) is provided with a ball seat (1), a steel ball (2), a valve bracket (3) and a spring (4) which are arranged in turn from left to right, the inner side of the right end of the valve body (10) is provided with a stopping piece (11) and a screw rod (13) connected with a pressing cap (12), and the upper end of the right part of the valve body (10) is provided with a bypassing short session (5). The utility model has the advantages that the associated gas can be recovered, and the oil-well-head associated gas can have the utilization value.
Description
Technical field:
The utility model relates to the used gas collection valve in oil field development field, belongs to well mouth of oil well getter valve.
Background technology:
Sustainable exploitation along with the oil field, a large amount of exploitations of crude oil, the continuous output of simultaneous gas, when the reduction of former oil pressure, most of accompanying gas will discharge, will cause waste if reclaim can not the utmost point time for companion's gas of output, associated gas can be collected utilization once more, serves the people, and does not have the gathering-device of associated gas at present, therefore most of associated gas has all been wasted, and has caused the waste of resource.
The utility model content:
In order to overcome the deficiency that associated gas can not reclaim, the utility model provides a kind of well mouth of oil well getter valve, and this getter valve has the characteristics of recyclable associated gas, can improve oil well associated gas utilization rate.
The technical solution of the utility model is: a kind of well mouth of oil well getter valve comprises valve body, valve body and pipe nipple vertical connection, pass through the intrinsic cone spool of key in the valve body, the conical surface of spool touches the right-hand member head that places threeway in the connector mutually, be equipped with ball seat, steel ball, valve carriage and spring in the spool from left to right successively, the valve body right-hand member is built-in with catch and the continuous leading screw of pressure cap, and valve body right part upper end is equipped with the bypass pipe nipple.
The beneficial effect that the utlity model has is: well mouth of oil well getter valve docks with the threeway of well mouth of oil well sleeve pipe, not only can play Sealed casing pipe gas, but also play the constant pressure turn on effect, and do not influence annulus logging, when casing pressure surpasses the setting opening pressure, level pressure air-release mechanism automatically unloading is pressed in the setting value to guarantee cover.Getter mechanism can separate utilization to the sleeve pipe gas income oil return flow process of emitting at petroleum transferring station, and this process seal performance is good, each position no seepage and no leakage, and average associated gas utilization rate is 76.3%.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model.
1-ball seat among the figure, 2-steel ball, 3-valve carriage, 4-spring, 5-bypass pipe nipple, 6-connector, 7-threeway, 8-pipe nipple, 9-spool, 10-valve body, 11-catch, 12-pressure cap, 13-leading screw, 14-key.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1, a kind of well mouth of oil well getter valve comprises valve body 10, valve body 10 and pipe nipple 8 vertical connections, pass through key 14 intrinsic cone spools 9 in the valve body 10, the conical surface of spool 9 touches the right-hand member head that places threeway 7 in the connector 6 mutually, be equipped with ball seat 1 in the spool 9 from left to right successively, steel ball 2, valve carriage 3 and spring 4, ball seat 1, steel ball 2, valve carriage 3, spring 4, threeway 7 and spool 9 have constituted envelope mechanism of qi structure, both can Sealed casing pipe gas, play the effect of constant pressure turn on again, when casing pressure surpassed the setting opening pressure of spring 4, this valve meeting automatically unloading was pressed in the setting value to guarantee cover; Valve body 10 right-hand members are built-in with the leading screw 13 that catch 11 and pressure cap 12 links to each other, and with special tool rotational lead screw 13, open test or well-flushing passage when test of needs sleeve pipe or well-flushing, bleed off sleeve pipe gas and carry out the annulus logging washing well; Valve body 10 right parts upper end is equipped with bypass pipe nipple 5, and getter mechanism links to each other with bypass pipe nipple 5, the sleeve pipe gas income oil return flow process of emitting, separates utilization at petroleum transferring station by bypass pipe nipple 5.
Because this getter valve docks with the threeway of well mouth of oil well sleeve pipe, not only can play Sealed casing pipe gas, but also play the constant pressure turn on effect, and not influence annulus logging or well-flushing, when casing pressure surpasses when setting opening pressure, level pressure air-release mechanism automatically unloading is pressed in the setting value to guarantee cover.Getter mechanism can separate utilization to the sleeve pipe gas income oil return flow process of emitting at petroleum transferring station, and this process seal performance is good, and each position no seepage and no leakage makes associated gas that value arranged.
