This utility model is related to a kind of sleeve type spray gun, solves the problems, such as that original spray gun can not coordinate existing integrated new technology to carry out bridging plug and use.Top connection, gun body, sliding sleeve and lower contact are specifically included, the top connection, gun body and lower contact are sequentially connected with by screw thread, the top of gun body wall is provided with spray-hole, and the bottom of gun body wall is provided with pin hole；Sliding sleeve is placed in gun body, is fixedly connected by shear pin therebetween, and the outer wall of sliding sleeve covers the spray-hole on gun body top；Nozzle is installed in spray-hole；Sliding sleeve comes downwards to bottom along lower contact inwall, and the lower surface of sliding sleeve is seated in the lower port of lower contact, spray-hole and gun body inner space.The sleeve type spray gun structure is simple, wearability is good, efficiency of construction is high, and bridging plug can be coordinated to realize bridging plug multistage hydraulic jetting fracturing institutional operation.
Description
Technical field
This utility model belongs to oil field well construction operation technical field of tools, and in particular to a kind of to be applied to bridging plug multistage
The sleeve type spray gun of hydraulic jetting fracturing.
Background technology
At present, hydraulic fracturing is still oilfield stimulation, augmented injection, it is ensured that a kind of effective means of oilfield stable production.Water-jet pressure
Split technology to be used in a large number in low permeability formation rebuilding construction, in order to meet coiled tubing bridging plug perforating and fracturing integral process
Demand, the spray gun that original split technique is used, because nozzle can produce backwash erosion and expanding in sandblasting procedures, spray gun makes
It is very short with the life-span, further, the spray gun can not coordinate integral process to carry out bridging plug use, so need to develop being adapted to integration
The spray gun that technique is used, so as to improve the intensity and efficiency of fracturing reform, reduces production cost.
The content of the invention
The sleeve type spray that this utility model provides a kind of reasonable in design, simple structure, wearability is good, efficiency of construction is high
Rifle, the spray gun is coordinated with bridging plug realizes bridging plug multistage hydraulic jetting fracturing institutional operation, by controlling ground wellhead back pressure, also
Many shower holes can be carried out.
For achieving the above object, the technical scheme adopted by this utility model is：A kind of sleeve type spray gun, including
Top connection, gun body, sliding sleeve and lower contact, the top connection, gun body and lower contact are sequentially connected with by screw thread, spray gun
The top of body wall is provided with spray-hole, and the bottom of gun body wall is provided with pin hole；Sliding sleeve two ends are furnished with sealing ring, and sliding sleeve is placed in
In gun body, it is fixedly connected by shear pin therebetween, the outer wall of sliding sleeve covers the spray-hole on gun body top；Spray
Install in perforation in nozzle cage, nozzle cage and nozzle is installed；Sliding sleeve comes downwards to bottom along lower contact inwall, and the lower surface of sliding sleeve is seated at
In the lower port of lower contact, spray-hole and gun body inner space.
It is preferred that the injection hole number on gun body is 4, and 4 spray-holes are divided into two groups, in this two groups of spray-holes
The heart is arranged in upper and lower two planes, and two spray-holes of same plane group are relative to substantially symmetrical about its central axis, this four sprays
Perforation center circumferentially between angle be 90 °.
It is preferred that pin hole number on gun body is 2, holes is symmetrical, two pin hole centers and one group of spray-hole
It is centrally located at same plane.
The beneficial effects of the utility model are：The sleeve type spray gun structure is simple, wearability is good, efficiency of construction is high, can
Bridging plug is coordinated to realize bridging plug multistage hydraulic jetting fracturing institutional operation, by controlling ground wellhead back pressure, moreover it is possible to carry out many clusters
Perforation, and nozzle can be effectively prevented in the backwash erosion of sandblasting procedures and expanding.
