Description
Technical field
The utility model relates to the kit of oil exploitation underground work process pipe string, particularly a kind of oil-water well downhole hydraulic rotational flow flushing device, is applicable to down-hole de-plugging construction.
Background technology
At present, many oil fields enter waterflood stage, oil, well in process of production due to wax deposition, shake out and the reason such as fouling, easily cause the problem such as casing wall fouling, tubing string blocking, need to carry out down-hole de-plugging cargo handling operation.Along with development process, annual job task amount is also all increase with it.Particularly offshore platform operation affects comparatively large by factors such as meteorology, sea situation, boats and ships, and de-plugging efficiency of construction in down-hole directly has influence on safety, the High-efficient Production of offshore oilfield.
Current conventional de-plugging power tool mainly contains following two kinds:
1, sand-washing pen point: be and carry G.I.H with the cylindrical body of lower inclined plane by oil pipe, current therefrom flow out, rinses the settling sand face in sleeve pipe and dirt.Tool construction is simple, and current scour limited efficiency, can not solve tube wall incrustation problem.
2, junk mill: be the discoid body of a lower surface with grinding sword, the fragment after grinding returns to ground with flushing fluid, enters this instrument at present when sand-washing pen point does not reach operation object.This instrument has certain effect to casing wall fouling, but cannot solve tube wall eyelet blockage problem.
Above-mentioned two kinds of instruments with the use of time, enter tubing string twice under needs, work operations amount is large, and ground environment pollutes large, and add development cost, what extend well in operation accounts for the well time.For meeting Production requirement, improving upkeep operation efficiency and well washing effect, removing oil-water well fouling, blocking fast, need development and improve current deblocking tool, reduce cost of production, shorten the workover treatment time.
Summary of the invention
The purpose of this utility model is to provide a kind of oil-water well downhole hydraulic rotational flow flushing device, overcomes the defect of prior art, improves the structure of existing instrument, and efficient solution oil removing well blocks, and shortens the activity duration, promotes de-plugging success rate, reduces cost of production.
The utility model is achieved in that
A kind of oil-water well downhole hydraulic rotational flow flushing device comprises sand-washing pen point, and the cylindrical of sand-washing pen point is provided with to scrape and chips, and the bottom of cyclone pipe is arranged in sand-washing pen point, its upper suspension is in top connection; Be arranged in top connection after adapter sleeve is connected with coiled tubing, be positioned at the top of cyclone pipe, the centre bore hole wall of cyclone pipe is provided with helicla flute, and coiled tubing is connected with high-pressure hydraulic pump on ground.
Described cyclone pipe is T-shaped pipe, and top is suspension step, lower end is provided with pod apertures between inclined-plane and centre bore.
The centre bore hole wall of described cyclone pipe processes helicla flute be communicated with pod apertures, the inclined-plane of its lower end conforms to the lower inclined plane of sand-washing pen point, can form water jet and spray from sand-washing pen point.
The utility model compared with prior art has following significant effect:
The utility model is that one utilizes coiled tubing to carry sand-washing pen point G.I.H to realize disposable operation, de-plugging operation under completed well.The cylindrical of sand-washing pen point is provided with to scrape and chips, the cyclone pipe be arranged in sand-washing pen point can provide water jet current, sand-washing pen point can rotate with cyclone pipe, has enough pressure to carry out de-plugging to sand face, down-hole and dirt, can carry out scraping to casing wall and tube wall eyelet simultaneously.Ground high-pressure hydraulic pump pressurizes, and downhole hydraulic eddy flow washes away the casing wall of cutting blocking, and silt particle returns out ground from oil jacket annular space.The utility model operation plugging removal effect is remarkable, and its concrete advantage is as follows:
1, continuous oil pipe operation, shortens the activity duration, saves man power and material, effectively reduces workover treatment cost;
2, water jet washes away, and eddy flow cutting and scraping, significantly improve plugging removal effect and success rate;
3, applied widely, can be used for the de-plugging job execution of various fouling oil-water well.
The utility model significantly improves de-plugging efficiency of construction and plugging removal effect, improves oil well output and water-injection efficiency.Compared to sand-washing pen point sand washing under current oil pipe and rush motionless after descend junk mill secondary operation again; on average every mouthful of well in operation descends one-trip string less, and the saving of the use of its instrument and operation labour cost is huge, effectively reduces cost of production; protect environment, there is significant economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing in detail the utility model is described in detail, and unrestricted protection domain of the present utility model, the improvement that all uses mentality of designing of the present utility model draws all belongs to protection category of the present utility model.
embodiment one
See Fig. 1, a kind of oil-water well downhole hydraulic rotational flow flushing device comprises sand-washing pen point 8, and the cylindrical of sand-washing pen point 8 is provided with to scrape chips 801, can carry out scraping while washing away to the dirt on casing wall.The bottom of cyclone pipe 6 is arranged in sand-washing pen point 8, its upper suspension is in top connection 5; Adapter sleeve 9 is arranged in top connection 5, is positioned at the top of cyclone pipe 6 after being connected with coiled tubing 1, the centre bore hole wall of cyclone pipe 6 is provided with helicla flute 602, and coiled tubing 1 is connected with high-pressure hydraulic pump on ground.Cyclone pipe 6 is T-shaped pipes, and top is suspension step, lower end is provided with pod apertures 603 between inclined-plane and centre bore.
