The inner cylinder of the concentric tube jet sand cleaning device is connected with an inner tube of a concentric tube in an insertion way, and the outer cylinder is connected with an outer tube of the concentric tube through thread of an oil tube; the outer thread of the bridge-type connector is connected with the inner thread of the outer cylinder; the guiding head is connected with the bridge-type connector through the thread of the oil tube, and the adjustable multi-level labyrinth valve and the sand mixing nozzle are arranged inside a circular hole in front of the side of the bridge-type connector. The concentric tube jet sand cleaning device has reasonable and compact structure; since the entire utilized flow liquid flows inside the concentric tube, the leakage and loss of the sand cleaning liquid and the sand carrying liquid is reduced, and the sand carrying efficiency is high. The problem that the sand is difficult to clean in the oil (water) well is effectively solved.
Description
One, technical field
The utility model relates to the sand removal plug-removing device of oil, well in the oil field, is a kind of concentric tube jet sand removal device.
Two, background technology
In the process of field produces, it is unavoidable problem that oil (water) well shakes out, and at present, oil (water) enters pit shaft though well has been taked screen sand control in a large number less than wide fine sand, the flour sand of screen casing seam.Present lot of domestic and international Oilfield using is dragged for technology such as sand, negative pressure sand washing, coiled tubing sand washing and is carried out oil (water) well sand removal operation, but complex structure, operating efficiency is lower, and these technology require high to corollary equipment, operating cost with the coiled tubing sand washing is very high, and pipe aperture can not meet the demands.
Three, summary of the invention
The utility model provides a kind of concentric tube jet sand removal apparatus, has overcome the deficiency of above-mentioned prior art, efficiently solves the problem of oil (water) well sand removal difficulty.
The technical solution of the utility model realizes by following measure: a kind of concentric tube jet sand removal device comprises urceolus, inner core, trunnion, lifting nozzle, bridge-type joint, guide head, labyrinth valve, stirs sand blasting mouth composition.The inner core of concentric tube jet sand removal device is connected by plug-in type with the interior pipe of concentric tube, and urceolus is connected by tubing round thread with the outer tube of concentric tube; The external screw thread of bridge-type joint is connected with the internal thread of urceolus; By tubing round thread guide head is connected on the bridge-type joint, the adjustable multistage labyrinth valve of packing into successively in the circular hole in side the place ahead of bridge-type joint, stirs the sand blasting mouth.
Be further optimization and/or improvements below to above-mentioned utility model technical scheme:
Power fluid is by the annular space between urceolus and the inner core, two groups of inlet openings on the bridge-type joint, and a part enters the lifting chamber, and another part enters and stirs the sand chamber;
Enter the power fluid in lifting chamber, form high velocity stream by the lifting nozzle and inject trunnion, between lifting nozzle and trunnion, low-pressure area is arranged.
The silt particle mixed liquor that stirs the sand blasting mouth in the pit shaft sucks from the side opening of urceolus, and to trunnion, anemostat, the interior pipe that enters concentric tube is lifted to ground through the suction passage pumping of bridge-type joint.
The bridge-type joint has the fluid course of three mutually noninterferes, promptly the lifting passage, stir sand passage, suction passage.
Stir the side front end of sand blasting mouth at guide head, the suction passage design is in the side of urceolus.
Guide head is equipped with multistage adjustable labyrinth valve and stirs the sand blasting mouth.
The utility model reasonable and compact in structure, the power fluid of use flow in concentric tube fully, have reduced sand removal liquid and load fluid to formation leakage, the sand-transport effeciency height.Effectively solved the problem of oil (water) well sand removal difficulty.
