Abstract
The invention provides a high-pressure hydrocyclone sand washing device, relating to a sand washing device, aiming at the problem that no professional sand washing tool is available for straight well or horizontal well sand washing and the disadvantages of large pump pressure loss, poor washing effect on well holes, easy tubular column clamping and difficult sand returning when guide cones, drills or grind shoes are used for sand washing. The invention is characterized in that one end of a high-pressure hydrocyclone sand washing device body is matched with a connecting pipe; a nozzle is arranged in the other end of the high-pressure hydrocyclone sand washing device body; the connecting pipe and the nozzle are in rotating connection; a jacket is arranged on the high-pressure hydrocyclone sand washing device body; two first through holes are arranged on the external wall of the high-pressure hydrocyclone sand washing device body along the central axis; two blind holes are arranged on the inner wall of the jacket along the central axis of the jacket; one end of each blind hole is arranged corresponding to the through holes; three second through holes are arranged on the inner wall of the other end of each blind hole; a nozzle is arranged in each second through hole; the nozzles and the blind holes are in rotating connection; and an upper joint and a lower joint are symmetrically arranged on the body along the central axis of the body. The sand washing device is used for straight well or horizontal well sand washing.
Description
Technical field
The present invention relates to a kind of sand washing machine.
Background technology
At present, general starting taper, drill bit or the junk mill etc. of adopting do not have special-purpose sand flushing tool when carrying out straight well or horizontal well sand washing, and when utilizing instrument sand washings such as starting taper, drill bit or junk mill, pumping pressure loss is big, and is poor to the developing result of pit shaft, easily block tubing string, and be unfavorable for sand return.
Summary of the invention
The purpose of this invention is to provide a kind of high pressure cyclone sand washing machine, when not having special-purpose sand flushing tool and utilizing starting taper, drill bit or junk mill sand washing when carrying out straight well or horizontal well sand washing at present to solve pumping pressure loss big, poor to the developing result of pit shaft, easily block tubing string and be unfavorable for the problem of sand return.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: described sand washing machine comprises body, overcoat, a plurality of nozzles, top connection and lower contact, one end and the tube connector of body are complementary, be provided with a nozzle in the other end of body, and the two is rotationally connected, body is provided with overcoat, the outer wall of body is provided with along its central axis and has two first through holes, the central axis of the inwall upper edge overcoat of described overcoat has two blind holes, the corresponding setting of one end of each blind hole with through hole, the inwall of the other end of each blind hole is uniformly distributed along the circumference and has three second through holes, be provided with a nozzle in each second through hole, and the two is rotationally connected, and top connection and lower contact are symmetricly set on the body along the body central axis.
The present invention has following beneficial effect: the present invention is provided with a plurality of nozzles, is distributed on the front end and circumferencial direction of body, and in sand washing process high speed rotation, and this kind structure makes pumping pressure loss little and guaranteed that pit shaft up and down and cleaning performance all around; Since the design of nozzle, but make the sand cleaning fluid high-pressure injection, and the pressure at nozzle place can reach 10-15MPa during use, and is strong to the impact force of pit shaft, not only can clean pit shaft, and the borehole of pit shaft is also had good cleaning action.The present invention has the effect of sand washing preferably, cleaning pit shaft, has guaranteed the production effect after the sand washing.
