Description
Technical field
The utility model belongs to well mouth of oil well valve member technical field, specifically is a kind of production wellhead oil jacket two-way admittance venting atmospheric valve that is applicable to oilfield.
Background technology
Producing well is adjusted the producing zone position according to the variation of oil well production in process of production, the oil reservoir that adopts mechanical system to come shutoff to stop adopting usually.After uppermost oil reservoir shutoff stopped adopting in the pit shaft, because stratum energy is restored, the liquid level of the oil sets annular space in the partial wells pit shaft rose to well head, has certain pressure; When the pressure in the pit shaft is lower than saturation pressure; Natural gas in the crude oil is separated from crude oil, because oil gas proportion is different, is not risen to oil sets annular space top by the natural gas of extraction; Form certain pressure at well head, this pressure is called casing pressure.When casing pressure was higher than the well head tubing pressure, mounting sleeve vent valve between sleeve valve and flow line made the interior oil gas of sleeve pipe lean on self pressure entering flow line, reaches the purpose of raising the output and control oil sets annular space liquid level.But existing sleeve pipe vent valve, passage is little, and can only unidirectional conducting, can't satisfy the production demand.And, when carrying out the well head upkeep operation, close the well head main valve earlier for the oil well that does not have casing pressure, and the oil gas in the well head oil pipeline is entered sleeve pipe, pressure falls and just can carry out construction operation after zero.For environmental protection production, do not allow to efflux crude oil, the method that adopts usually is to carry out emptying after the rubber flexible pipe is inserted sleeve pipe; For preventing to get rid of after the rubber pipe racks from pressing, its emptying valve can not be opened greatly, thereby emptying time is longer; Sometimes higher because of oil well energy; Release is slow, and emptying time is longer like this, rate when directly having influenced oil recovery.
The utility model content
The purpose of the utility model provides a kind of integrate sleeve pipe venting, oil pipe emptying, can be with the production wellhead oil jacket two-way admittance venting atmospheric valve of the oil-gas automatic discharging in the down-hole casing to flow line.
The technical scheme that the purpose of realization the utility model is taked is: this device has the valve body of a straight pipe; One end of valve body is provided with the screw thread that is connected with oil well casing valve clip head, is provided with the gas channel hole in the valve body, and valve seat, valve ball, spring, spring base, adjusting screw(rod) and adjusting pole socket are housed successively; Wherein, Regulate to adopt between pole socket and the valve body being threaded, adjusting screw(rod) and spring base are connected as a single entity, and are threaded onto in the adjusting pole socket; And with regulate pole socket and be threaded; Side at valve body is provided with the air vent short circuit that is communicated with valve body gas channel hole, and the outside of short circuit is connected with the rubber flexible pipe through active joint, and the other end of rubber flexible pipe is connected with the valve of flow line through active joint.
The external part of said adjusting screw(rod) is provided with spanner card side.
Between said spring base and the adjusting pole socket sealing ring is housed.
The connecting portion of said air vent short circuit and rubber flexible pipe is equipped with sealing mat.
According to the production wellhead oil jacket two-way admittance venting atmospheric valve that such scheme is processed, through the opening pressure that adjusting screw(rod) is regulated valve ball, can realize the level pressure venting, make the pressure reduction between oil pipeline and the sleeve pipe be controlled at reasonable range.And the rubber flexible pipe through being provided with, realize convenient the connection with petroleum pipeline, when reaching setting pressure in the oil well casing, open valve and sleeve valve on the flow line, can be through this valve with the oil-gas automatic discharging in the down-hole casing to flow line.Compared with prior art, this valve has the two-way admittance function of sleeve pipe venting and oil pipe emptying, and easy installation and removal, and good reliability can satisfy the production demand of different oil wells.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Referring to Fig. 1, the production wellhead oil jacket two-way admittance of the utility model venting atmospheric valve, this device has the valve body 1 of a straight pipe; One end of valve body 1 is provided with the screw thread that is connected with oil well casing valve clip head, is provided with the gas channel hole in the valve body 1, and valve seat 2, valve ball 3, spring 7, spring base 8, adjusting screw(rod) 10 is housed successively and regulates pole socket 11; Wherein, Regulate to adopt between pole socket 11 and the valve body 1 being threaded, adjusting screw(rod) 10 and spring base 8 are connected as a single entity, and are threaded onto in the adjusting pole socket 11; And be threaded with regulating pole socket 11, the external part of adjusting screw(rod) 10 is provided with spanner card side 12.For improving its sealing, between spring base 8 and adjusting pole socket 11, sealing ring 9 is housed.Side at valve body 1 is provided with the air vent short circuit 1-1 that is communicated with valve body gas channel hole; The outside of short circuit 1-1 is connected with rubber flexible pipe 5 through active joint 4; And sealing mat 6 being housed at the connecting portion of air vent short circuit 1-1 and rubber flexible pipe 5, the other end of rubber flexible pipe 5 is connected with the valve of flow line through active joint.
Operating principle: the atmospheric valve level of will exitting is installed on the clip head of sleeve valve, and the active joint 4 at rubber flexible pipe 5 two ends connects the valve on venting atmospheric valve and the flow line respectively, and sleeve pipe oil gas backs down valve ball 3, gets into flow line through rubber flexible pipe 5.Through the opening pressure that adjusting screw(rod) 10 is regulated valve ball 3, realize the level pressure venting, make the pressure reduction between oil pipeline and the sleeve pipe be controlled at reasonable range.Spring base 8 and spring 7 interference fit; During to wellhead flowline emptying, rotate adjusting screw(rod) 10 at the well head upkeep operation, screw rod moves and drives spring 7 outer moving outward; Valve ball 3 lifts off a seat 2 under the self gravitation effect; Fall in the chamber, open valve and sleeve valve on the flow line, oil gas gets into sleeve pipe through the valve core channel of rubber flexible pipe 5 and venting atmospheric valve.This valve has the two-way admittance function, can realize sleeve pipe venting, oil pipe emptying in one, adopts oil formula active joint in the ninth of the ten Heavenly Stems to connect easy installation and removal simultaneously.Alternative original sleeve pipe vent valve also can be made atmospheric valve and use, and can satisfy the production demand of different oil wells.
