Abstract
The utility model relates to an external force type pressure testing releasing valve which comprises a valve body, a gravity ball stirring device, a steel ball and a ball seat. The utility model is characterized in that the external force type pressure testing releasing valve is in the shape of a column, the valve body is a connecting body which is used for connecting an upper fuel tube with the ball seat by threads, and the ball seat is a connecting body which is connected with a lower fuel tube by threads. The gravity ball stirring device in the valve body stirs up the steel ball on the ball seat. The upper part and the lower part of the valve body are provided with female threads, while the middle part is provided with a righting cavity for the gravity ball stirring device. The rim of a hole on the upper part of the ball seat is provided with a cone angle which is matched with the steel ball for sealing. The upper part and the lower part of the ball seat are provided with male thread. The external force type pressure testing releasing valve is connected in series with the lower part of a flow string.
Description
One, technical field
The utility model relates to the external force pressure testing relief valve that a kind of oil well repairing operation is used.
Two, background technology
At present after the oil well shaft bottom is buried by sand, oil well is just not fuel-displaced, the well workover of being forced to stop production, mainly use the waterpower sand washing process during well workover, with cementing truck water is thrown into from oil pipe, return out ground from sleeve pipe, water carries out ground with the sand in shaft bottom, through removing sand filter sand filtration is gone out, the water storage tank is standby, after hydraulic sand washing finishes, the pitching pressure testing, will again oil well pump be arrived the shaft bottom down with tubing string after the tubing string proposition after pressure testing is qualified, so just the water of pressure testing is taken out of ground when playing oil pipe, splash is on ground, and contaminated environment influences job execution.
Three, summary of the invention
The purpose of this utility model provides a kind of external force formula pressure testing relief valve, solves when playing tubing string and takes pressure testing water out of the ground pollution environment, influences the job execution problem.
The utility model is dialled ball device, steel ball and ball seat by valve body, gravity and is formed, it is characterized in that external force formula pressure testing relief valve is cylindrical, valve body is the connector that the top oil pipe is threaded with ball seat, ball seat is the connector that is connected with the bottom tubing round thread, and gravity is dialled the steel ball that the ball device will be sitting on the ball seat and pushed aside in valve body.The valve body top and the bottom are provided with box thread, and the middle part is made as the lifter cavity that gravity is dialled the ball device, and the endoporus edge of ball seat upper end is provided with cone angle, and with the steel ball fitted seal, the top and the bottom of ball seat are provided with male thread, and external force formula pressure testing relief valve valve body is serially connected in the bottom of tubing string.
It is cylindrical that gravity is dialled the ball device, and its external diameter is less than the internal diameter of valve body, on the same vertical line of the upper and lower side of the same all sides of cylinder, be provided with cylinder be made as one up and down two set upright post, setting upright the post bottom is made as cone down.
The utility model is connected the bottom of tubing string, changed the tubing string structure, had, made oil pipe trip out ground without pressure testing to tubing string pressure testing function and pressure release function, sewage is not taken out of ground when playing oil pipe, reduce oil pipe pressure testing difficulty and the pollution that has prevented ground environment.

Five, specific embodiment
For further disclosing the technical solution of the utility model, be described in detail by embodiment below in conjunction with Figure of description:
The utility model is dialled ball device 2, steel ball 3 and ball seat 4 by valve body 1, gravity and is formed, it is characterized in that external force formula pressure testing relief valve is cylindrical, valve body 1 is the connector that the top oil pipe of tubing string is threaded with ball seat 4, ball seat 4 is the connectors that are connected with the bottom tubing round thread of tubing string, and gravity is dialled the steel ball 3 that ball device 2 will be sitting on the ball seat and pushed aside in valve body 1.Valve body 1 top and the bottom are provided with box thread, and the middle part is made as the lifter cavity that gravity is dialled ball device 2; The endoporus edge of ball seat upper end is provided with cone angle, and with the steel ball fitted seal, the top and the bottom of ball seat are provided with male thread, and the utility model is serially connected in the bottom of tubing string.Oil well is when ordinary production, gravity is dialled the ball device and steel ball is kept at ground, when the oil pipe pressure testing steel ball is knocked down oil pipe to steel ball from well head, and steel ball drops on the ball seat by gravity, seal with ball seat, throw the tubing string pressure testing into cement handlebar water, after having tried pressure, gravity is dialled the ball device knock down tubing string from well head, drop into valve body by gravity, gravity is dialled the following cone of setting upright post of ball device ball is pushed aside, and the water of tubing string is let out in the sleeve pipe, and sewage just can not take the ground pollution environment to when playing tubing string.
Claims (2)
