Abstract
The utility model relates to a tool which prevents liquid in an oil pipe from spraying outwards for lifting a pipe column, wherein the upper and the lower ends of a cylinder body are respectively provided with end covers, and the shape of each of the end covers forms a circular shape. Two circular baffles are fixed in the cylinder body, and the distance between the two circular baffles is 150 to 500 millimeters. Circular capsules are arranged between the circular baffles and the end covers. The outer surface of each of the circular capsules is provided with a gas inlet which can provide high pressure gas for the capsules. The center diameters of the end covers, the circular capsules and the baffles are 50 to 150 millimeters. The side surface of the cylinder body is fixed with a liquid guide pipe. The utility model has the effects that the end part of the oil pipe is sealed by adopting a capsule inflated mode, the sprayed liquid is controlled and collected, and the tool achieves the purposes of maintaining well site cleanness, improving operation environment and preventing environmental pollution.
Description
Affiliated technical field
The utility model relates to the oil field development technical field, particularly a kind ofly when carrying and rising fuel-displaced, well tubing string, prevents the instrument of the outer spray of liquid in the tubing string last.Adopt capsule inflation mode sealed tube column end, concentrate by the liquid that mozzle is collected staving.The utlity model has good practical value.To keeping the well site cleaning, improve operating personnel's working environment, prevention well site surrounding environment is polluted, and can play special role.Be adapted at oil, in the operation of well tubing string or promote the use of in other lift pipe string operation.
Background technology
Hundreds of oil pipes are all arranged in each producing well, adopt between the oil pipe to be threaded togather, length reaches thousands of rice.When well workover, pump detection and workover, these oil pipes need be tripped out ground.Oil pipe is risen to ground one by one, the screw thread between the oil pipe outwarded winding.Behind the tubing round thread of outwarding winding, the liquid in the oil pipe of top sprays from the oil pipe bottom.Liquid contains water and crude oil is sprayed at the well site, causes well site operating personnel work very difficult.The more important thing is: substantial oil sprays on the ground, and natural environment causes severe contamination around giving.The operating personnel that have adopt and simply split the liquid that iron sheet tube blocks ejection.This way can only prevent the liquid splash on one's body the workman, but the liquid of ejection still will flow on the well site, can not overcome liquid fully the well site is polluted and problem of environmental pollution.Up to the present, do not find that also there are reliable way or instrument in the job site, when having solved oil pipe, the outer spray problem of liquid in the oil pipe.
Summary of the invention
The purpose of this utility model is: a kind of inflation self-sealing drainage tube is provided, adopts capsule inflation mode to seal and dismantle oil pipe end, control is also collected the liquid of ejection, reaches to keep the well site cleaning, improves operating environment, the purpose of prevention environment pollution.
The utility model is that the scheme that its technical problem of solution is taked is: at the cylindrical shell upper and lower end end cap is arranged respectively, end cap be shaped as annular.Be fixed with two ring baffles in cylindrical shell, the distance between two ring baffles is between the 150-500 millimeter.Annular capsule is arranged between ring baffle and the end cap.Annular capsule external surface has air inlet port, can provide gases at high pressure to capsule, and annular capsule is expanded.End cap, annular capsule and its centre bore dia are between the 50-150 millimeter.Be fixed with catheter in the cylindrical shell side, the liquid of ejection is collected in the liquid collecting jar by catheter and flexible pipe.
The position of air inlet port can also can be located near the plane of baffle plate or near on the plane of end cap at the lateral surface of annular capsule.
The beneficial effects of the utility model are: adopt capsule inflation mode to seal the oil pipe end of dismantling, the liquid of top oil pipe ejection is controlled in the cylindrical shell, and can collect the liquid of ejection, reached maintenance well site cleaning, improve workman's operating environment, the most important thing is to prevent the liquid of ejection that environment is polluted.
Description of drawings
Accompanying drawing 1 is the utility model overall structure generalized section.When carrying on the expression oil pipe (1), the annular capsule (3) of inflation self-sealing drainage tube is in the free state of unaerated.The direction of arrow indication is the direction of carrying on the oil pipe (1).
Accompanying drawing 2 is the utility model overall structure generalized sections.Expression oil pipe (1) is dismantled, and the annular capsule (3) of inflation self-sealing drainage tube is in the inflation state.The direction of arrow indication is the direction that top oil pipe (1) ejection liquid flows through.
Among the figure, 1. oil pipe, 2. end cap, 3. annular capsule, 4. baffle plate, 5. cylindrical shell, 6. catheter, 7. air inlet port.
The specific embodiment
Embodiment 1: as accompanying drawing, one is applicable to that external diameter is that the inflation self-sealing drainage tube of 60 millimeters oil pipes (1) is an example, describes.Cylindrical shell (5) diameter is 350 millimeters, highly is 400 millimeters, and adopting thickness is that 3 millimeters steel plates are welded into, and there is flange at two ends.Upper and lower end has end cap (2) respectively, end cap (2) be shaped as annular, external diameter is 460 millimeters, internal diameter is 80 millimeters.End cap has screw hole on (2), can be screwed on consubstantiality (5) flange.In cylindrical shell (5), be welded with two ring baffles (4), 80 millimeters of baffle plate (4) diameter of bores.Distance between two ring baffles (4) is at 200 millimeters.Between ring baffle (4) and the end cap (2) an annular capsule (3) is arranged respectively.388 millimeters of annular capsule (3) external diameters, 80 millimeters of internal diameters, 90 millimeters of height, 8 millimeters of wall thickness.Annular capsule (3) air inlet port (7) is located on annular capsule (3) outer ring surface, and each annular capsule (3) has an air inlet port (7).Side in cylindrical shell (5), lower baffle plate (4) top is welded with catheter (6), and catheter (6) adopts 60 millimeters steel pipe manufacturings of diameter.Air inlet port (7) connects high-pressure hose and is connected with air pump, and air pressure is about 0.7MPa.Catheter (6) connects flexible pipe, liquid is imported the liquid collecting jar focus on.
Embodiment 2: basic identical with embodiment 1, difference is the position of air inlet port (7).An annular capsule (3) air inlet port (7) is located on the outer ring surface; The air inlet port (7) of another annular capsule (3) is located in the cylindrical shell (5), promptly adopts high-pressure rubber pipe that two annular capsules (3) are communicated with (accompanying drawing 1).
