Specific embodiment
In conjunction with the description of attached drawing and specific embodiment of the present invention, the utility model can be clearly understood
Details.But specific embodiment of the present utility model described herein, it is only used for explaining the purpose of this utility model, without
It can be understood as being limitations of the present invention in any way.Under the introduction of the utility model, technical staff is contemplated that
Any possible deformation based on the utility model, these are regarded as belonging to the scope of the utility model.
As shown in Figure 1, the utility model proposes a kind of combinations to salvage wimble device 100, which salvages wimble device 100 and includes
The cylindrical body that top connection 110, female coupling tap 120 and die nipple 130, top connection 110 and female coupling tap 120 are vertically arranged, die nipple 130 are served as reasons
Gradually the circular cone stage body of undergauge, die nipple 130 are installed in 110 bottom end of top connection under, and female coupling tap 120 is set in outside die nipple 130, female
The top of cone 120 is fixedly connected with the outer wall of die nipple 130, and the inner wall of female coupling tap 120 is gradually expanding circular conical surface from top to bottom,
The bottom end of die nipple 130 and the inner wall of female coupling tap 120 have interval, and the bottom end of female coupling tap 120 is equipped with the magnetite portion 121 of annular.
The utility model proposes combination salvage wimble device 100 die nipple and female coupling tap are organically combined, can salvage
The junk of different size, the process that die nipple, female coupling tap are replaced when reducing salvaging, shortens the fishing period, improves salvaging
The efficiency of operation.
The utility model proposes combination salvage wimble device 100, the bottom end of female coupling tap 120 is provided with magnetite portion 121, magnetite
Portion 121 is the magnetic patch of annular.In this way, magnetite portion 121 can play a protective role when salvaging small falling object, junk and mother are prevented
It is violent between cone to collide with or squeeze.
The utility model proposes combination salvage wimble device 100, structure is simple, processing get up it is easier, cost is relatively low.
The utility model proposes combination salvage wimble device 100 it is easy to operate, can thread making salvage: the operating instruction of the device
As common die nipple, female coupling tap, can thread making salvage, it is easily operated；And it can repeatedly use, be hardly damaged.
The utility model proposes combination salvage wimble device 100 salvage significant effect, particularly with dual string butterfish roof fall
Well casing column, the salvaging significant effect for falling the outer lead body of well lead stamp, falling well packer rubber, improve work efficiency, reduce operation
Cost.
In the utility model one optional example, the side wall of top connection 110 offers water hole 111, water hole 111
Along the side wall for extending radially through top connection 110 of top connection 110.In this way, after salvaging successfully, due to gravity, the water of fishing string
During upper lifting pipe post (including wimble device 100 is salvaged in combination), down-hole liquid can flow out from water hole 111, prevent
Top lifting jet pipe operation in operation.
In the utility model one optional example, flow channels 131 up and down are offered on die nipple 130.
In the utility model one optional example, the internal diameter of water hole 111 is less than or equal to 131 internal diameter of flow channels
Half.When due to fishing, salvage successful key be observe turn on pump rinse when, rinse top of fish pump pressure become
Change, and the pump pressure for rinsing top of fish is identical as pressure at 130 flow channels 131 of die nipple；The internal diameter that water hole 111 is arranged is less than or waits
In the half of 131 internal diameter of flow channels, also avoid to influence 130 overcurrent of die nipple because the internal diameter of water hole 111 is excessive
Pressure at channel 131, and then also avoid the variation of the pump pressure on ground and be difficult the case where judging.
In the utility model one optional example, the outer diameter of female coupling tap 120 is identical as the outer diameter of top connection 110.In this way,
The outer diameter that wimble device 100 is salvaged in combination is consistent on the whole, avoids in casing deformation well that tubing string is stuck, also avoids to salvage multiple
Hydridization, it is final to guarantee that fishing be gone on smoothly.
In the utility model one optional example, top connection 110 is made of one piece with die nipple 130.
In the utility model one optional example, female coupling tap 120 and die nipple 130 are threadedly coupled.
The utility model proposes combination salvage wimble device 100 be achieved in that
Firstly, wimble device 100 is salvaged in assembling combination, female coupling tap 120 is set in outside die nipple 130 and makes female coupling tap 120 and die nipple
130 are threadedly coupled；
Later, combination is salvaged the connection tubing string of wimble device 100 and gone into the well by the specific location that top of fish is verified after drifting, printing；
When tool is down toward 1~2 meter of top of fish top, turn on pump is rinsed, and gradually transfers tool to top of fish, observation pump pressure variation,
If pump pressure is flown up, suspending weight decline illustrates that fish enters combination and salvages wimble device 100, thread making can be carried out, such as suspending weight decline
Pump pressure is without significant change, then Ying Shangti drill string, rotates drill string, again to fish, until pump pressure and suspending weight have significant change, ability
The thread making that pressurizes is salvaged.
It should be noted that not allowing the top of fish that pauses suddenly in fishing operation, to prevent top of fish or salvaging screw thread is bad.
In the present invention, the female coupling tap 120 of multiple and different internal diameters and the die nipple of multiple and different outer diameters can be set
130, the specification for the fish salvaged as needed selects suitable female coupling tap 120 and die nipple 130 to assemble, to improve fishing
Success rate.
For explaining in detail for the respective embodiments described above, purpose, which is only that, explains the utility model, in order to
It better understood when the utility model, still, these descriptions cannot be with any explanation at being limit to the utility model
System, in particular, each feature described in various embodiments can also mutual any combination, to form other implementations
Mode, in addition to there is clearly opposite description, these features should be understood to can be applied in any one embodiment, and simultaneously
It is not only limited to described embodiment.
