Abstract
The utility model provides an ejector for blocking removal, and belongs to an oilfield production device. The ejector comprises an upper joint, a mounting cylinder is fixed below the upper joint, a connecting pipe is fixed below the mounting cylinder, a jet cavity is formed at the lower end of the connecting pipe, a sealing ring is arranged between the jet cavity and the connecting pipe, a bearing is arranged below the sealing ring, a plurality of nozzles are arranged on the lateral surface of the jet cavity, each nozzle is provided with an oblique liquid outlet, and a plug is arranged at the lower end of the jet cavity. The ejector for blocking removal is reasonable in structure; blocking removal is carried out on a sand preventing pipe by using rotary jet flow, so that gathered granules can be crushed; and the ejector has a good blocking removal effect, and does not cause environmental pollution.
Description
Technical field
The utility model provides a kind of field produces device, especially a kind of de-plugging device.
Background technology
In oilfield process, usually with sand-proof pipe completions such as screen casing or bushing pipes.Along with the carrying out of oil producing operation, the migration particle in the sand-proof pipe is more and more, results in blockage, and normal oil recovery of impact produced.In the method for removing blockage of taking at present chemical plugging removal is arranged, namely carry out de-plugging with workover fluid, but the use of workover fluid can cause secondary environmental pollution, and be difficult to workover fluid is sent into obstruction face, plugging removal effect is undesirable.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of de-plugging ejector, to improve plugging removal effect.
The utility model is to realize like this, the de-plugging ejector, it has top connection, is fixed with mounting cylinder below the top connection, is fixed with tube connector below the mounting cylinder, the lower end of tube connector is equipped with the injection cavity, spraying between cavity and the tube connector has sealing ring, bearing is arranged below the sealing ring, and the spray chamber body side surface is equipped with a plurality of nozzles, the fluid hole that inclination is arranged on the nozzle, there is plug the lower end of spraying cavity.
Adopt the de-plugging ejector of said structure, rational in infrastructure, it utilizes rotating jet that sand-proof pipe is carried out de-plugging, the particle of assembling can be smashed, and plugging removal effect is good, and can not cause environment pollution.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies concrete structure of the present utility model and operating principle.
As shown in drawings, the de-plugging ejector of the utility model, it has top connection 1, is fixed with mounting cylinder 2 below the top connection, is fixed with tube connector 4 below the mounting cylinder, the lower end of tube connector is equipped with sprays cavity 7, spraying between cavity and the tube connector has sealing ring 5, bearing 6 is arranged below the sealing ring, and the spray chamber body side surface is equipped with a plurality of nozzles 9, the fluid hole 8 that inclination is arranged on the nozzle, there is plug 10 lower end of spraying cavity.
During use, top connection is installed on the hollow section by the external screw thread above it.Then, enter the sand-proof pipe position of down-hole with hollow section.To be with press liquid to send into the injection cavity through top connection inner chamber, mounting cylinder inner chamber, tube connector inner chamber, the at last ejection of the fluid hole from the nozzle.Because fluid hole 8 be inclined hole, therefore, spray cavity and produce rotation, thereby the obstruction in the flushing, impact sand-proof pipe is finished de-plugging.The liquid stream that tilts can produce eddy current effect, and the rotation of spraying cavity also can impact by mineralization pressure, has further improved plugging removal effect.
The mounting cylinder external surface can have the groove 3 of being convenient to the instrument clamping.
Fluid hole can be radial skew, namely is not orthogonal to the spray chamber body axis.
