Abstract
A magnetic-suction pressure testing valve is provided with a valve body, a valve ball, a valve seat and a valve seat joint. The valve seat is mounted in the valve body, the upper portion of the valve seat joint is connected with the lower portion of the valve body, the upper end surface of the valve seat joint is abutted to the lower end surface of the valve seat, the upper end surface of the valve seat is abutted to a shoulder in the valve body, the valve ball is seated on the valve seat, tubing threads are disposed on the upper portion of the valve body, a magnet frame and a strong magnet are arranged in the valve body, the strong magnet is mounted in the magnet frame, and the magnet frame and the strong magnet are positioned above the ball valve. After the valve ball is seated on the valve seat, a tubing string is in a closed state, and operators can test the pressure of the tubing string. The magnet frame and the strong magnet are placed into the valve body after the pressure of the tubing string is tested, the valve ball is sucked by the magnetic force of the strong magnet so as to be separated from the valve seat, the tubing string is in a non-closed state and vertically communicated, and the operators can perform construction operation such as direct flushing, direct sand washing and the like. When the tubing string is lifted, fluid in a tubing flows into a well without being extracted out of the ground, and environments cannot be polluted. Accordingly the magnetic-suction pressure testing valve has remarkable economic benefit and social benefit.
Description
Technical field
The utility model belongs to the underground equipment that oil well repairing operation is used, and is a kind of magnetic-type pressure testing valve.
Background technology
In the oil-water well well workover, often need carry out construction operations such as positive and negative circulation well cleanup, positive sand washing, finish in order to guarantee operation, need before construction operations such as positive and negative circulation well cleanup, positive sand washing, carry out pressure testing to the oil pipe that is lowered to, whether the check oil pipe meets the requirements.Way to the oil pipe pressure testing is in the tubing string bottom one way valve to be installed at present, making the tubing string on the ball-and-seat is between airtight going bankrupt or broke, thereby can be to the tubing string pressure testing, but after pressure testing finished, liquid stream can only flow from bottom to top, can not flow from the top down, therefore can not carry out construction operations such as direct flushing, positive sand washing, when carrying tubing string, the liquid in the oil pipe can not flow in the well, can be suggested ground, cause environment pollution.
Summary of the invention
The purpose of this utility model is a kind of magnetic-type pressure testing valve of design, its pressure testing is finished after, tubing string can UNICOM, can carry out construction operations such as direct flushing, positive sand washing, when carrying tubing string, the liquid that can not in the oil pipe is suggested ground, and is free from environmental pollution.
The purpose of this utility model has been achieved in that valve body, valve ball, valve seat, valve base joint, valve seat is installed in the valve body, valve base joint top is connected with valve body lower portion, the valve seat lower surface is withstood in the valve base joint upper surface, and the valve seat upper surface withstands on the interior shoulder of valve body, and the valve ball seat is on valve seat, tubing round thread is arranged at valve body top, magnet frame, strong magnet are arranged in the valve body, and strong magnet is installed in the magnet frame, and magnet frame, strong magnet are on the valve ball.
The beneficial effects of the utility model are: the valve ball seat is after on the valve seat, tubing string is an air-tight state, can be to the tubing string pressure testing, after pressure testing is finished to tubing string, drop into magnet frame, strong magnet, the magnetic force of strong magnet holds valve ball, and valve ball is lifted off a seat, and tubing string is non-air-tight state, tubing string is UNICOM up and down, can carry out construction operations such as direct flushing, positive sand washing, when carrying tubing string, the liquid in the oil pipe flows in the well, can not be suggested ground, free from environmental pollution, therefore, the utlity model has remarkable economic efficiency and social benefit.
Description of drawings
Accompanying drawing 1 is an assembling drawing of the present utility model.
The specific embodiment
1 couple of embodiment of the present utility model describes below in conjunction with accompanying drawing.
Embodiment of the present utility model is by magnet frame 1, strong magnet 2, valve body 3, valve ball 4, valve seat 5, valve base joint 6 is formed, valve seat 5 is installed in the valve body 3, valve base joint 6 tops are connected with valve body 3 bottoms, valve seat 5 lower surfaces are withstood in valve base joint 6 upper surfaces, valve seat 5 upper surfaces withstand on the shoulder in the valve body 3, make firm being installed in the valve body 3 of valve seat, and can realize pressure testing the time liquid that can not from valve seat outside seepage, 4 of valve balls are on valve seat 5,4 of valve balls are after on the valve seat 5, valve ball 4 and valve seat 5 fitted seal, tubing round thread is arranged at valve body 3 tops, is used for being connected with the top tubing string, and magnet frame 1 is arranged in the valve body 3, strong magnet 2, strong magnet 2 is installed in the magnet frame 1, magnet frame 1, strong magnet 2 is on the valve ball 4.Screw thread is arranged at magnet frame 1 top, can connect weighted lever, and its delivery is put in place.
During use, valve ball is taken out, valve body 3 is connected the bottom of tubing string, when needing pressure testing after putting in place down, drop into valve ball 4,4 of valve balls back on valve seat 5 needs tubing string up and down during UNICOM to the tubing string pressure testing after pressure testing is finished, drop into magnet frame 1, strong magnet 2, after magnet frame 1 bottom is landed on the shoulder in the valve body 3, strong magnet 2 picks up valve ball, and tubing string is UNICOM up and down, can carry out other operation.
