Abstract
The invention relates to the field of oil production engineering and belongs to a large-scale anti-back-spattering sand blower for the oil tube fracturing, which can be used for solving the problems that a sand blower is poor in abrasion resistance and is worn due to back-spattering sandblasting in an oil tube fracturing process in the past. The large-scale anti-back-spattering sand blower comprises an upper joint (1), a filter screen (2), a nozzle (3), a pressure guide body assembly (4), an anti-rotation pin bolt (5), a lining (6), an alloy gasket (7), a rubber protecting jacket (8), an alloy protecting ring (9), an alloy spacer (10), a rubber protecting piece (11), a fixed pin bolt (12), an aligning body (13), rubber spacers (14) and slot bodies (15). The large-scale anti-back-spattering sand blower is mainly applied to large-scale fracturing processes and has the advantages of excellent temperature resistance and pressure resistance, safe and reliable process and the like.
Description
Technical field
The present invention relates to petroleum production engineering field, belong to a kind of anti-backwash sanding machine of oil pipe massive hydraulic fracture.
Background technology
Unconventional aboundresources at present, tight gas, fine and close oil and mud stone oil reservoir exploitation potentiality are big, but well yield is low,
Need massive hydraulic fracture renovation technique to realize yield to break through.But at present pressure-guiding sand blower in multistage massive hydraulic fracture process
In, sanding machine steel body is easily abraded, and pressure break is taken sand backwash and easily caused tool failures, leads to the problem that pressing crack construction can not be carried out.
Therefore, in order to solve problem above, invented new oil pipe pressure break anti-backwash sanding machine on a large scale.
Content of the invention
It is an object of the invention to provide can in oil pipe pressure break large scale process erosion resistant, anti-backwash, sand control sanding machine,
Thus effectively improving a kind of oil pipe pressure break anti-backwash sanding machine on a large scale of its service behaviour.
The technical scheme is that and realized by following measures：
It is protected by top connection, filter screen, nozzle, pilot body assembly, anti-rotation pin, bushing, alloy packing ring, rubber protecting jacket, alloy
Retaining ring, alloy pad, rubber screening glass, fixing pin, centralizer body, rubber sheet gasket and trough composition；Wherein filter screen is embedded into
In joint, top connection is threadeded with pilot body assembly, and is fixed by anti-rotation pin, is sequentially arranged with spray inside pilot body assembly
Mouth, bushing, alloy packing ring, alloy pad and rubber screening glass, nozzle contact connection is stuck at the shoulder at pilot body assembly top,
Rubber screening glass contact connect be stuck at the shoulder of pilot body assembly bottom, alloy protecting ring set outside pilot body assembly, rubber
Glue protective case is enclosed within outside alloy protecting ring, and centralizer body is fixed on pilot body assembly by fixing pin, embedding in pilot body assembly
Enter rubber sheet gasket and trough.
Pilot body assembly has pilot passage from top to bottom.
Design for porous type in the middle part of bushing.
Pilot body assembly and trough all adopt carbide alloy YG 8.
Alloy protecting ring adopts carbide alloy YG 8.
Compared with the prior art the present invention has the advantage that：
This sanding machine structure is simple, and performance safety is reliable, efficiently solves existing sanding machine in horizontal well massive hydraulic fracture process
Middle Abrasion properties are poor, backwash sand washing damage instrument the problems such as, improve the security reliability of fracturing technology tubing string.
Brief description：Fig. 1 is present configuration sketch, and Fig. 2 is pilot body assembly 4 and the profile of bushing 6 middle part A-A.
The top connection of in figure 1-, 2- filter screen, 3- nozzle, 4- pilot body assembly, 5- anti-rotation pin, 6- bushing, 7- alloy packing ring,
8- rubber protecting jacket, 9- alloy protecting ring, 10- alloy pad, 11- rubber screening glass, 12- fixing pin, 13- centralizer body, 14-
Rubber sheet gasket, 15- trough, pilot passage 16.
Specific embodiment：Below in conjunction with the accompanying drawings invention is described further：
It is by top connection 1, filter screen 2, nozzle 3, pilot body assembly 4, anti-rotation pin 5, bushing 6, alloy packing ring 7, rubber protecting jacket
8th, alloy protecting ring 9, alloy pad 10, rubber screening glass 11, fixing pin 12, centralizer body 13, rubber sheet gasket 14 and trough 15
Composition；Wherein filter screen 2 is embedded in top connection 1, and top connection 1 is threadeded with pilot body assembly 4, and is fixed by anti-rotation pin 5,
It is sequentially arranged with nozzle 3, bushing 6, alloy packing ring 7, alloy pad 10 and rubber screening glass 11, nozzle 3 connects inside pilot body assembly 4
Tactile connection is stuck at the shoulder at pilot body assembly 4 top, and rubber screening glass 11 contact connects the platform being stuck in pilot body assembly 4 bottom
At shoulder, alloy protecting ring 9 is enclosed within outside pilot body assembly 4, and rubber protecting jacket 8 is enclosed within outside alloy protecting ring 9, centralizer body 13 by
Fixing pin 12 is fixed on pilot body assembly 4, embedded rubber sheet gasket 14 and trough 15 in pilot body assembly 4.
