Description
Technical field
The utility model relates to a kind of well washing apparatus, particularly a kind of well-washing device that utilizes jet washing well.
Background technology
In order to extend the application life of packer and to improve sealing effectiveness, Daqing oil field fractional water flooding down-hole has entered not well packer capable of flushing well layering oil pipe, due to can not well-flushing, time has been grown the well having and has occurred that injection rate declines, along with long use, a large amount of greasy dirts are deposited in well, have caused oil well to note the situation of not intaking, need integral replacing Wel packing, caused the waste of resource.
Summary of the invention
The utility model is intended to propose a kind of jet-flow well-washing apparatus.
A kind of jet-flow well-washing apparatus described in the utility model, comprise the cylindrical body of hollow, body interior is provided with the plugging device that is movably set in body interior, a part for described body sidewall extends to outside and is provided with a fluidic device, this fluidic device is provided with water inlet and delivery port, described water inlet extends to body exterior, and described delivery port is connected with body interior, and described water inlet and delivery port arrange respectively and plugging device both sides.
Preferably, described fluidic device inside is provided with horn-like ejector and infundibulate nozzle, and this infundibulate nozzle and horn-like ejector are socketed mutually, and described infundibulate nozzle is arranged at water inlet.
A kind of jet-flow well-washing apparatus described in the utility model, this this device is socketed on oil pipe, when normal water filling, packer is opened, when clean-out service by packer shutoff, flushing fluid is injected from sleeve pipe, flushing fluid is entered from water inlet, from delivery port, discharge, the utility model is simple in structure, practical.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model; .
1-body in figure; 2-plugging device; The horn-like ejector of 3-; 4-infundibulate nozzle.
Detailed description of the invention
A kind of jet-flow well-washing apparatus described in the utility model, comprise the cylindrical body 1 of hollow, body 1 inside is provided with the plugging device 2 that is movably set in body 1 inside, a part for body 1 sidewall extends to outside and is provided with a fluidic device, this fluidic device is provided with water inlet and delivery port, described water inlet extends to body 1 outside, described delivery port is connected with body 1 inside, water inlet and delivery port arrange respectively and plugging device 2 both sides, fluidic device inside is provided with horn-like ejector 3 and infundibulate nozzle 4, this infundibulate nozzle 4 and horn-like ejector 3 are socketed mutually, described infundibulate nozzle 4 is arranged at water inlet.
A kind of jet-flow well-washing apparatus described in the utility model, is connected to jet-flow well-washing apparatus on oil pipe, is arranged at not washing well envelope device top, do not affect at ordinary times normal water filling work, in the time of needs well-flushing, open water inlet and delivery port, drop into blanking plug from well head, water enters from sleeve pipe, under the effect of jet-flow well-washing apparatus, pumping formation fluid is returned out from water main, through well-flushing several times so repeatedly, just can make obstruction pass through to rinse back and forth loosening, be pumped into ground, reach the object of de-plugging.Flushing device for water injection well described in the utility model, utilize the high pressure water liquid that is used as power injecting from sleeve pipe, pass through successively infundibulate nozzle 4 and horn-like ejector 3, form high-speed jet at water outlet, make pressure decreased around form low-pressure area, well liquid carries obstruction under the effect of strata pressure, returns out ground from oil pipe.
