The oil-gas mining of industrial gas oil is on-the-spot generally all to be in the open-air open environment, especially, many oil-gas minings scene is nearer far from the village, therefore, often there is illegal villager to adopt the form that connects sleeve pipe to steal gas and robber's sleeve pipe oil, not only cause tremendous loss, also cause the environment pollution incident of increased area often to country.Because installations and facilities are destroyed, increased oil recovery wellblock management difficulty and cost expenditure, also increased worker's labour intensity.
The utility model content
The purpose of this utility model provides a kind of use can prevent the antitheft level pressure recovery valve of the stolen sleeve pipe oil gas of sleeve pipe oil gas.
For realizing above-mentioned utility model purpose, the technical scheme of the antitheft level pressure recovery valve of sleeve pipe oil gas provided by the utility model is: the antitheft level pressure recovery valve of a kind of sleeve pipe oil gas, comprise a valve body, valve body is installed in below the down-hole rising short circuit, valve body comprises a hollow core hole, and the upper and lower end of valve body is arranged with the oil pipe screw thread; Also be provided with the level pressure that is communicated with the hollow core hole by connecting through hole on the valve body and reclaim ball-and-seat, this level pressure reclaims ball-and-seat and comprises a core hole, one end in core hole is provided with air inlet, the inboard of air inlet is provided with valve seat and valve ball, the other end in core hole is provided with plug and spring, and the end of spring props up valve ball.
Also be provided with the well-flushing ball-and-seat on the described valve body, this well-flushing ball-and-seat comprises a core hole, and an end in core hole is provided with air inlet, and the inboard of air inlet is provided with valve seat and valve ball, and the other end in core hole is provided with hollow plug and spring, and the end of spring props up valve ball.
Described valve seat and valve ball cooperate for grinding.
The outer wall of described valve body is provided with two seal grooves, in the described seal groove y-type seal ring is installed.
The beneficial effects of the utility model: the utility model is installed in below the down-hole rising short circuit, has the advantage of not destroyed by the fellow-villager, can in time put sleeve pipe gas into oil pipe automatically, in time recovery of casing gas.The utility model is equipped with the well-flushing ball-and-seat and guarantees that sleeve pipe kill-job well-flushing normally carries out, and guarantees that well-flushing and sleeve pipe throughput satisfy the production needs.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model actual installation structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.
Fig. 1 is the utility model structural representation, as shown in fig. 1, and the antitheft level pressure recovery valve of the utility model sleeve pipe oil gas, comprise valve body 1, valve body 1 is installed in below the down-hole rising short circuit, from about 30 meters of well head, valve body 1 comprises a hollow core hole 2, and the upper and lower end of valve body 1 is arranged with oil pipe screw thread 3; Also be provided with the level pressure that is communicated with hollow core hole 2 by connecting through hole 4 on the valve body 1 and reclaim ball-and-seat 5, this level pressure reclaims ball-and-seat 5 and comprises a core hole 51, one end in core hole 51 is provided with air inlet 52, the inboard of air inlet 52 is provided with valve seat 53 and valve ball 54, the other end in core hole 51 is provided with plug 55 and spring 56, the end of spring 56 props up valve ball 54, and valve seat 53 and valve ball 54 cooperate for grinding.
Also be provided with well-flushing ball-and-seat 6 on the valve body 1, this well-flushing ball-and-seat 6 comprises a core hole 61, one end in core hole 61 is provided with inlet opening 62, the inboard of inlet opening 62 is provided with valve seat 63 and valve ball 64, the other end in core hole 61 is provided with hollow plug 65 and spring 66, the end of spring 66 props up valve ball 64, and valve seat 63 and valve ball 64 cooperate for grinding.
Fig. 2 is the utility model actual installation structural representation, as shown in Figure 2, valve body 1 is installed in below the down-hole rising short circuit position from about 30 meters of well head, therefore have the characteristics that stolen oil gas person destroys that are difficult for, valve body 1 is installed in the sleeve pipe 7, the upper and lower side of valve body 1 is connected with oil pipe 8 by oil pipe screw thread 3 respectively, when the sleeve pipe atmospheric pressure surpasses tubing pressure 0.1 MPa, the valve ball 54 that level pressure reclaims ball-and-seat 5 is open, oil gas in the sleeve pipe 7 is by air inlet 52, core hole 51, connecting through hole 4 enters in the oil pipe 8 (shown in filled arrows among the figure), plays oil gas recovery effect.When sleeve pipe atmospheric pressure during less than 0.1 MPa, level pressure reclaims the valve ball 54 of ball-and-seat 5 and closes automatically under the effect of spring 55, prevents oil gas in the oil pipe 8 sleeve pipe 7 that flows backwards back.Therefore, the utlity model has when stolen gas person connects sleeve pipe 7 and steals, close level pressure and reclaim ball-and-seat 5, thereby prevent that the oil gas in the sleeve pipe 7 is stolen.
During well-flushing, when pressure reaches 0.1 MPa, well-flushing ball-and-seat 6 is opened, flushing fluid enters sleeve pipe 7 by hollow plug 64 and carries out well-flushing or kill-job (shown in Fig. 2 hollow core arrow), when pressure during less than 0.1 MPa, well-flushing ball-and-seat 6 is closed under the effect of spring 65 automatically, prevents that the oil gas of sleeve pipe 7 from flowing out in sleeve pipe.
In addition, in order to solve and avoid the gap that sleeve pipe rising short circuit and sleeve pipe actual diameter dwindle 2mm, the utility model adopts the outer wall at valve body 1 that two seal grooves are set, and Y-shaped sealing ring 7 is installed in the seal groove.2 grades of Y-shaped sealings that the utility model adopted can be shut the pressure in oil jacket space fully.
As well known to the skilled person; the foregoing description only plays the exemplary role in the above-mentioned utility model protection scope; for those of ordinary skills; also have a lot of conventional distortion and other embodiment in the protection domain that the utility model limited, these distortion and embodiment will be within the protection domains that the utility model awaits the reply.
