Description
Technical field
The utility model relates to a kind of oil well pump blowout prevention standing valve, belongs to tubing pump lifting implement and underground blow-out preventing device technical field in natural petroleum gas field.
Background technology
When lower oil pump tubing string, because borehole pressure is high, often can there is oily liquid in pipe and gush in underground work, well-flushing, kill-job are main blowout prevention operations.Well-flushing pressure reduction is high, and pump truck pressure and pressure and hydrostatic pressure sum be stressor layer above Ground, can cause a large amount of working fluids to enter formation oil stream channel, produces water lock, causes oleic permeability to decline, and well oil output reduces.In the prior art, use cock as jet-preventing tool in oil pipe, at oil pipe, gush and rob when dress, because life period is poor, can cause job site environment pollution, after installation, carry out could continuing construction after well-flushing, kill-job, so not only there is the hidden danger of injury oil reservoir, contaminated environment, also can increase operating cost, incur loss through delay operation and drive a well.
The patent No. 99215855.9 discloses a kind of oil field machinery oil standing valve for oil-well pump, and it is comprised of joint, valve bonnet, valve seat, valve body, by operation sucker rod, can valve body be lifted to valve seat and put back to valve seat with drop handle.Thereby can make the oil well pump with this standing valve realize motionless oil well pipe and complete gas injection, sand washing, clear well and sealing function, realize the oil draining function in workover treatment.But the hidden danger of gushing in oil pipe in the time of can not solving under underground work oil pump tubing string.
Summary of the invention
The purpose of this utility model is can not realize the defect of snubbing serving in order to overcome above-mentioned standing valve of the prior art, and a kind of multi-functional standing valve is provided.
The utility model is comprised of standing valve cover, upper valve base, valve ball, lower valve base, pressed joint, cylindrical shell, and standing valve cover is threaded successively with cylindrical shell, pressed joint, and standing valve cover upper surface has gas channel, is provided with upper valve base in standing valve cover; In cylindrical shell, be provided with spring pedestal, lower valve base from top to bottom, spring stop piece is installed on spring pedestal, valve ball is placed in the upper valve base and the cavity between the spring stop piece on spring pedestal of standing valve cover.
The beneficial effects of the utility model are by the sealing of upper valve base and valve ball, and in barrierwell, liquid enters in oil pipe, realizes snubbing serving, the generation of the accident that can effectively prevent the pollution of the environment, can avoid hydraulic slip in oil pipe, accelerate job execution progress, save operating cost simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model is comprised of standing valve cover 1, upper valve base 2, valve ball 3, lower valve base 5, pressed joint 6, cylindrical shell 7, standing valve cover 1 is threaded successively with cylindrical shell 7, pressed joint 6, and standing valve cover 1 upper surface has gas channel 8, is provided with upper valve base 2 in standing valve cover 1; In cylindrical shell 7, be provided with spring pedestal 4, lower valve base 5 from top to bottom, spring stop piece 9 is installed on spring pedestal 4, valve ball 3 is placed in the upper valve base 2 and the cavity between the spring stop piece 9 on spring pedestal 4 of standing valve cover 1.
Described spring pedestal 4 tops are evenly equipped with 3 or 4 spring stop pieces 9.
Described upper valve base 2, lower valve base 5 are taper or spherical structure.
Described standing valve cover 1 upper surface is evenly equipped with 3 or 4 gas channels 8.
When the pumping pipe string of high-pressure oil gas down-hole, standing valve cover 1 of the present utility model is connected with pump barrel by its screw thread, pressed joint 6 is connected with afterbody oil pipe by its screw thread, when borehole pressure raises, promote valve ball 3 up, realize end face seal with upper valve base 2, stop liquid in well to enter in oil pipe; Instantly during complete pumping pipe string, in oil pipe, just suppress, make valve ball 3 descending, press off spring pedestal 4 internal upper part spring stop pieces 9 and realize end face seal with lower valve base 5, guarantee that oily liquid in pipe do not miss, eliminate the hidden danger that environmental pollution accident easily occurs at high-pressure oil gas down-hole pumping pipe string, simplified flow chart, saved operating cost.
