The problems such as bulk junk is difficult to salvage (screw, nut and stone etc.) in industry be present, scrap collecting is stranded in milling bridging plug operation
Difficulty, the efficiency and safety of drilling well are drastically influence, especially during geothermal drilling, because severe mud losses often result in well ring
Sky loses and returned, and occurs landwaste the problem of can not effectively carrying, a large amount of talus deposits to occur, cause shaft bottom sand setting so that make a trip, under
The operations such as sleeve pipe have difficulties and risk.Because the presence of underground sand setting is, it is necessary to repeatedly during geothermal well casing job
Highly viscous drilling fluid is broken into well or is circulated for a long time, to carry out dosing cement job in the case of severe leakage,
Then new well is bored, is repeated and is squeezed into high viscosity drilling fluid and carry out cleaning shaft bottom, then tripping in sleeve pipe again.This technics comparing
It is cumbersome, it is necessary to multiple trips and drill operation, have a strong impact on operating efficiency and cost be higher.
Utility model content：
The technical problems to be solved in the utility model is to provide a kind of geothermal well sand setting fishing tool, the arrangement achieves
Underground sand setting can effectively be salvaged, it is ensured that geothermal well well cleans, and operation process is simple and convenient safe and reliable, and operating efficiency is high,
Operating cost is substantially reduced, meets high-temperature geothermal underground working, can be worked in high temperature, high grinding and corrosive environment.Overcome
Existing geothermal drilling sand setting process operations process is cumbersome, and operating efficiency is low, and operating cost is high, it is dangerous it is reliable not
Foot.
Technical solution adopted in the utility model is：A kind of geothermal well sand setting fishing tool, including top connection is with
Joint；Top connection lower end outer wall connects nozzle connection, and nozzle connection corresponds to be provided with jet hole in opposite direction up and down, under top connection
Inwall connection nozzle bushing pipe is held, nozzle open obliquely, nozzle connection, landwaste surge drum, point bits are designed with nozzle bushing pipe
Cylinder, lower contact are sequentially connected with from top to bottom, and landwaste surge drum upper end inwall connection classification screen casing, landwaste surge drum lower end inner wall connects
Garbage collection cylinder is connect, the sieve aperture of garbage collection cylinder is more than the sieve aperture of classification screen casing, and check valve is placed in garbage collection cylinder lower end, unidirectionally
Valve lower end connection valve pipe, valve pipe lower end are connected in lower contact.
Nozzle connection upper end side wall is circumferentially angularly provided with four jet holes open obliquely, nozzle connection bottom side of the wall
It is circumferential to be angularly provided with four jet holes opened obliquely.
Nozzle bushing pipe is circumferentially angularly designed with four nozzles.
The beneficial effects of the utility model are：The utility model, which realizes, can effectively salvage underground sand setting, it is ensured that underground heat
Well well cleans, and operation process is simple and convenient safe and reliable, and operating efficiency is high, substantially reduces operating cost, meets high-temperature geothermal
Underground working, it can be worked in high temperature, high grinding and corrosive environment.
Brief description of the drawings：
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the profile of the nozzle on nozzle bushing pipe.
Embodiment：
As shown in Figure 1 and Figure 2, a kind of geothermal well sand setting fishing tool, including top connection 1 and lower contact 11；Top connection 1
Lower end outer wall connects nozzle connection 2, and nozzle connection corresponds to about 2 and is provided with jet hole in opposite direction, and the lower end inner wall of top connection 1 connects
Connect nozzle bushing pipe 3, be designed with obliquely open nozzle 4 on nozzle bushing pipe 3, nozzle connection 2, landwaste surge drum 6, point bits cylinder 7,
Lower contact 11 is sequentially connected with from top to bottom, the upper end inwall connection classification screen casing 5 of landwaste surge drum 6, the lower end inner wall of landwaste surge drum 6
Garbage collection cylinder 8 is connected, the sieve aperture of garbage collection cylinder 8 is more than the sieve aperture of classification screen casing 5, and the utility model is by being classified screen casing 5
Multistage collection chamber is designed with garbage collection cylinder 8, can be according to the size dimension of landwaste, implementation tool internal classification, in optimization
Cylinder volume, reaches the maximum for collecting landwaste.Check valve 9 is placed in the lower end of garbage collection cylinder 8, the lower end connection valve pipe 10 of check valve 9,
The lower end of valve pipe 10 is connected in lower contact 11, and check valve 9 can make the smooth entering tool inner cylinder of landwaste, while can only open upwards
Open, realize single file, control function, in the case that landwaste is collected into necessarily, the function of revealing all the details can be played.
The upper end side wall of nozzle connection 2 is circumferentially angularly provided with four jet holes open obliquely, the lower end side of nozzle connection 2
Wall is circumferentially angularly provided with four jet holes opened obliquely.Nozzle bushing pipe 3 is circumferential to be angularly designed with four nozzles 4.
The utility model utilizes well fluids downhole jet swabbing action, establishes a high speed partial fluid reacting cycle flow field, well
Lower chip inside entering tool, and moves up, in instrument under the drive that high-velocity fluid and instrument rotate from inside center
