Abstract
The utility model relates to a test tube drain device, which belongs to the technical field for verifying the sealability of a well tube column after the operation of an oil-water well of an oil field, and consists of a sealing sliding sleeve, a pressure release sealing seat and a sealing ball seat, the sealing sliding sleeve is a tubular body with the upper end being sealed, the wall of the upper part of the sealing sliding sleeve is provided with a guide hole, the lower part of the sealing sliding sleeve is connected with the pressure release sealing seat through a pin; the pressure release sealing seat is a tubular body with the upper end being sealed, the lower end of the pressure release sealing seat is of a spherical structure, and the upper part of the wall of the pressure release sealing seat is provided with a pressure release hole; the lower end spherical surface of the pressure release sealing seat seals the sealing ball seat, and both the upper end and the lower end of the sealing ball seat are provided with connection threads. The test tube drain device has beneficial effects that: after an effect of a test tube is realized, the pressure balance of the upper part and the lower part of the lower well tube column can be realized by striking the sealing sliding sleeve, and the fluid can be prevented from being brought away to the ground in working, so the operation environment can be improved, and the environment pollution can be reduced.
Description
Technical field
The utility model relates to a kind of pipe earial drainage device of testing, behind the genus oil field oil water well operations, and the technical field of the device of checking running string sealing.
Background technology
Oil-water well needs the sealing of checking tubing string in operation process, generally be that ball seat is installed on tubing string in advance, behind design attitude, drops into steel ball and suppresses under the tubing string; According to the pressure stability situation, judge the tubing string sealing.The invar ball can't be pulled out after dropping into, and when mentioning flowline in the oil-water well operation, the fluid in the tubing string is scattered near the well head, not only causes the operating worker condition of work to worsen, and then causes environment pollution when serious.
The patent No. is that 200720187772.6 patent discloses a kind of sleeve type and tests the pipe device, and what only be applicable to water injection well tests plumber's preface.
Summary of the invention
The purpose of the utility model is to provide a kind of operating environment that improves, and reduces testing of environment pollution and manages the earial drainage device.
The technical scheme that the utility model adopted is:
The utility model is made up of sealing sliding sleeve, pressure release seal receptacle, sealed ball seat, and the sealing sliding sleeve is the tubular body of upper end sealing, has pod apertures on the tube wall at an upper portion thereof, and sealing sliding sleeve bottom is connected through pin with the pressure release seal receptacle; The pressure release seal receptacle is the tubular body of upper end sealing, and its lower end is a spherical structure, on the tube wall of pressure release seal receptacle top, has relief hole; Pressure release seal receptacle lower end sphere sets on sealed ball seat, and sealed ball seat two ends up and down is a connecting thread.
Relief hole at the pressure release seal receptacle is separately installed with sealing ring one and sealing ring two in two ends up and down.
The sealed ball seat upper end is the sphere that cooperates with pressure release seal receptacle lower end sphere.
The beneficial effect of the utility model is, after realizing testing the effect of pipe, can realize running string upper and lower pressure balance through bump sealing sliding sleeve, takes fluid to ground when avoiding operation, thereby realizes improving operating environment, reduces environment pollution.
Description of drawings
Fig. 1 is the sectional view of the utility model.
1 sealing sliding sleeve among the figure, 2 sealing rings, one, 3 sealing ring, two, 4 pins, 5 pressure release seal receptacles, 6 sealed ball seats, 7 oil pipes, 8 tail pipes.
The specific embodiment
The utility model is made up of sealing sliding sleeve 1, pressure release seal receptacle 5, sealed ball seat 6, and sealing sliding sleeve 1 has pod apertures 1a at an upper portion thereof for the tubular body of upper end sealing on the tube wall, and sealing sliding sleeve 1 bottom is connected through pin 4 with pressure release seal receptacle 5; Pressure release seal receptacle 5 is the tubular body of upper end sealing, and its lower end is a spherical structure, on pressure release seal receptacle 5 top tube walls, has relief hole 5a; Pressure release seal receptacle 5 lower end spheres set on sealed ball seat 6, sealed ball seat about in the of 6 two ends be connecting thread.
The two ends up and down of the relief hole 5a of described pressure release seal receptacle 5 are equipped with sealing ring 1 and sealing ring 23.
Said sealed ball seat 6 upper ends are the sphere that cooperates with pressure release seal receptacle 5 lower end spheres.
Under the oil-water well operation during oil pipe, with sealed ball seat 6 upper ends be threaded with oil pipe 7, the lower end is threaded with tail pipe 8, with the utility model with the running string G.I.H; Test and manage when suppressing,,, can realize verifying the sealing of oil pipe 7 top tubing strings according to pressure changing because pressure release seal receptacle 5 sets on sealed ball seat 6.After testing the duct ligation bundle; Through throwing bar bump sealing sliding sleeve 1; To pin and 4 cut off, sealing sliding sleeve 1 is descending, and the relief hole 5a on the pressure release seal receptacle 5 is communicated with the pod apertures 1a that seals sliding sleeve 1; The relief hole 5a of the liquid of oil pipe 7 top tubing strings on pressure release seal receptacle 5 and the pod apertures 1a of sealing sliding sleeve 1 get into tail pipe 8, realize earial drainage.
