Abstract
The utility model discloses a novel compound fisher belongs to the oil field and uses borehole operation tools technical field. Including the urceolus, the one end of urceolus links to each other with the top connection, and the other end of urceolus is with the guide shoe is continuous down, two slice gliding sliders about the inner wall of urceolus is provided with the slide and can follows the slide are 180 jiaos of settings between two sliders, be provided with the same power of stinging device of four groups at the inner wall lower part of urceolus from the top down, every group stings power device evenly distributed on the urceolus inner wall and becomes 3 rows and each other be 120 degrees angles and set up, the power of stinging device can sting the power piece around its pivoted including the rolling bearing of welding on the urceolus inner wall, last being connected with of rolling bearing, sting the power piece and still link to each other with the one end of spring, the other end of spring is connected on the inner wall of urceolus. The utility model discloses both can level screwed rule oil pipe junk to the section and salvage, also can salvage the irregular oil pipe junk of the irregular screw thread of section disappearance, can effectively improve fishing operation efficiency.
Description
Technical field
The utility model relates to a kind of oil field underground operation tool, is specifically related to a kind of NEW TYPE OF COMPOSITE fisher, is specially adapted to downhole oil tubing fishing junk and uses.
Background technology
Existing for downhole oil tubing junk in oil field, its fishing tool has die nipple, female coupling tap, sliding block trip spear etc., from tubing string outer wall or inwall, mainly enter fishing tool implement to salvage, but due to underground structure and junk situation complexity, not easily salvage, these power tools have its limitation, and reliability and success rate are all difficult to accomplish the end in view.
Utility model content
The utility model, for above-mentioned prior art Problems existing, provides a kind of NEW TYPE OF COMPOSITE fisher.
The technical solution adopted in the utility model is to achieve these goals: a kind of NEW TYPE OF COMPOSITE fisher, comprises urceolus, and one end of urceolus is connected with top connection, and the other end of urceolus is connected with lower guide shoe; At the two panels slide block that the inwall of urceolus is provided with slideway and can slides up and down along slideway, arrange in 180 ° of angles between two panels slide block; Four groups of identical biting force devices are provided with from top to bottom at the inner wall lower of urceolus, often organize biting force device and on outer tube inner wall, be evenly distributed into 3 rows mutually in 120 degree of angles settings, described biting force device comprises the rolling bearing be welded on outer tube inner wall, rolling bearing is connected with the biting force sheet that can rotate around it, biting force sheet is also connected with one end of spring, and the other end of spring is connected on the inwall of urceolus.
Slide block is at outer tube inner wall by forming in the two panels at 180 degree angles mutually, and it is 120 degree of angles mutually that 4 groups that are simultaneously made up of spring, biting force sheet, rolling bearing identical biting force devices are evenly distributed into 3 rows on outer tube inner wall.As preferably, its length is 100mm, and its length is 40mm, and biting force leaf length is 60mm, width is 15mm, and rolling bearing diameter is 10mm.
Design feature of the present utility model is that oil pipe junk enters in urceolus through lower guide shoe, first oil pipe junk applies pressure to biting force sheet, biting force sheet then bites the screw thread on oil pipe by spring force, then along with oil pipe continue enter slide block and start stressed, hold oil-pipe external wall tightly further, more salvage oil pipe junk to close and firm, form compound and salvage.Thus both can salvage the smooth threaded regular oil pipe junk of section, also can salvage the irregular oil pipe junk of section irregular screw thread disappearance.
The utility model top connection connected pipes, in decentralization process, lowering velocity is slowed down when distance top of fish 1-2 rice distance, down-hole oil tube fish can be brought in urceolus by lower guide shoe, then oil pipe junk first can be subject to slide block biting force by biting force sheet biting force again, after confirming that suspending weight declines, near top of fish, handling is for several times back and forth up and down in position repeatedly, oil pipe junk is tightly bitten stressed, then slowly on carry observe suspending weight change, get final product greatly upper lifting pipe post to well head as suspending weight becomes, whole salvaging process successfully terminates, thus completes salvaging action.
The convenient production of the utility model, handled easily, reliability is high, wide accommodation, can effectively improve fishing efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1. top connection, 2. urceolus, 3. slide block, 4. spring, 5. biting force sheet, 6. rolling bearing, 7. descend guide shoe.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of NEW TYPE OF COMPOSITE fisher of the utility model, comprise urceolus 2, one end of urceolus 2 is connected with top connection 1, and the other end of urceolus 2 is connected with lower guide shoe 7; At the two panels slide block 3 that the inwall of urceolus 2 is provided with slideway and can slides up and down along slideway, arrange in 180 ° of angles between two panels slide block 3; Four groups of identical biting force devices are provided with from top to bottom at the inner wall lower of urceolus 2, often organize biting force device and on urceolus 2 inwall, be evenly distributed into 3 rows mutually in 120 degree of angles settings, described biting force device comprises the rolling bearing 6 be welded on urceolus 2 inwall, rolling bearing 6 is connected with the biting force sheet 5 that can rotate around it, biting force sheet 5 is also connected with one end of spring 4, and the other end of spring 4 is connected on the inwall of urceolus 2.During work, first down-hole oil tube junk can be brought in urceolus 2 by lower guide shoe 7, then oil pipe junk can first by biting force sheet 5 biting force again by slide block 3 biting force, dually tightly drag for oil pipe junk with joint efforts.
