Abstract
The present invention relates to a casing hydraulic pulse flushing device. It is composed of jet flow head, sand-cleaning nozzle, couple nozzle, cleaning nozzle, damper, guider, pin bolt, flushing pipe and filter. Said invention also provides their connection mode and working principle of said flushing device.
Description
One, technical field
The present invention relates to a kind of oil production equipment technical field, utilize the inner pipe water pressure pulse flushing device of high-pressure water jet flushing in the anti-sandpipe of specifically a kind of horizontal well.
Two, background technology
The sand preventing tool that present oilfield horizontal well, high angle hole generally adopt is the anti-sandpipe of metal species, the fine sand of oil reservoir outflow flows into anti-sandpipe or stops up sand control pore crack in process of production, cause output to reduce or stopping production, the device that is not suitable at present flushing in the anti-sandpipe of horizontal well, therefore, be badly in need of a kind of device that horizontal well, high angle hole wash that is suitable in anti-sandpipe.
Three, summary of the invention
The purpose of this invention is to provide a kind of inner pipe water pressure pulse flushing device, solve the problem that the interior sand control pipe plug plug of horizontal well and high angle hole well influences crude output.
Technical scheme of the present invention realizes in the following manner:
The present invention is by the jet head, the sand washing nozzle, the couple nozzle, washer jet, damper, guider, pin, washing pipe and strainer are formed, the screen casing that it is characterized in that strainer is threaded with washing pipe, washing pipe is threaded with the reducer union of damper by the guider center, the rotor of damper is connected by bearing with the damping body, damper rotor is connected with the jet head thread, the sand washing nozzle is contained in the axial top of jet head, the couple nozzle is contained on the jet nose cone face by certain phase angle side direction, and washer jet is pressed certain phase angle radially loading on the jet centriciput face of cylinder; The guider lower end by dowel fixes in the damper reducer union.
Strainer is made up of tubular filter screen, strainer pressure cap, screen casing and circular housing, and the tubular filter screen set is at the screen casing external surface, and both ends and screen casing weld; Circular housing is enclosed within tubular filter screen appearance, and the circular housing upper end is provided with reducer union, and the reducer union upper end is connected with the construction tubing round thread, and its lower end is threaded with screen casing, and the circular housing lower bottom part welds with screen casing.
Washing pipe length is slightly less than the length of down-hole sand control tubing string.
Guider is made as cylindrical shape, and the semicircle that is welded with symmetry in its appearance is set upright the wing.
Damper rotor is made as a quill shaft.
The sand washing nozzle is made as cylindrical, and the couple nozzle is established cylindric flat, and washer jet is established cylindric streamlined.Three nozzles are equipped with male thread, are connected with the jet head thread.
The sand control pipe that the present invention has solved horizontal well and high angle hole preferably stops up the problem of back de-plugging, saved because of sand control pipe stops up to cause and carried tubing string, the relieve a garrison well workover program of sandpipe, improved the application life of anti-sandpipe, saved workover cost, rate when having improved oil well production is filled up the blank of this technology.
Four, description of drawings
Accompanying drawing is a structural representation of the present invention

Five, the specific embodiment
For further disclosing technical scheme of the present invention, elaborate by embodiment below in conjunction with Figure of description:
The present invention is by jet head 1, sand washing nozzle 2, couple nozzle 3, washer jet 4, damper 5, guider 6, pin 7, washing pipe 8 and strainer 9 are formed, the screen casing that it is characterized in that strainer 9 is threaded with washing pipe 8, washing pipe 8 is threaded with the reducer union of damper by guider 6 centers, the rotor of damper 5 is connected by bearing with the damping body, damper rotor is threaded with jet head 1, sand washing nozzle 2 is contained in jet head 1 axial top, couple nozzle 3 is contained on the jet nose cone face by certain phase angle side direction, and washer jet 4 is pressed certain phase angle radially loading on the jet centriciput face of cylinder; The guider lower end is fixed in the damper reducer union by pin 7.
When using, the oil pipe 10 of will constructing is connected with strainer 9, the screen casing of strainer is connected with washing pipe 8, washing pipe is connected with the reducer union of damper 5 by guider 6, the rotor of damper is connected with jet head 1, the week side is installed washer jet 4 on the face of cylinder, middle part of jet head, install couple nozzle 3 in all sides of the jet head bottom conical surface, install sand washing nozzle 2 at the jet cephalic par, with construction oil pipe 10 this device is arrived sand control pipe down, under process in, guider is to sleeve pipe break-in place, pin 7 is cut off, and guider continues descending guiding, and the jet head is during to sand control pipe, ground high-pressure hydraulic pump water filling in oil pipe, water filters through filter, enters damper through washing pipe, because of the internal diameter of rotor diminishes, current have been carried out damping, increased flow velocity and entered the jet head, the sand washing nozzle dashes the sandstone that buries anti-sandpipe, and the couple nozzle makes sand fully mix with water, ground is easy to carry, washer jet is along with descending process, to outer injection water, will prevent that the sandpipe filter screen leaves over sand and rinse out in the anti-sandpipe, return ground with sand cleaning fluid, in the sand washing process, the jet head is rotation all the time under the effect of jet, makes sand washing, washed-out sand is even, the anti-sandpipe of flushing is effective.
