Abstract
The utility model relates to a fishing tool for grasping and fishing from the inside of caught fish in well repairing and fishing job construction, in particular to a telescoping spear. The telescoping spear comprises a fishing body, a spider, a spring, a connecting body and a connector, wherein, the spider is sleeved outside the fishing body, the spring is sleeved on the fishing body and above the spider, the connecting body is arranged at one end of the fishing body and the connector is connected with the connecting body through threads. The telescoping spear can synchronously meet the requirement of connection with oil tubes with different specifications and drill rods and also has the advantages of reduced labor intensity of the workers and high fishing efficiency.
Description
Technical field
The utility model relates in a kind of oil field well workover fishing construction grabs the fishing tool that drags for from fish inside, a kind of specifically flexible lance that drags for.
Technical background
Dragging for lance is in the construction of oil field well workover fishing, fishing tool commonly used, and the existing lance that drags for generally can not satisfy and the oil pipe of different size and being connected of drilling rod simultaneously owing to the restriction that is subjected to structure.Complex structure, operation inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of simple and reasonable, can satisfy simultaneously and the oil pipe of different size and being connected of drilling rod, can reduce working strength of workers, salvages the high flexible lance that drags for of efficient.
The purpose of this utility model is to realize like this, lance be should flexible drag for and salvaging body, slips, spring, connector, joint comprised, described slip sleeve is contained in the outside of salvaging body, spring housing be contained in salvage on the body, slips above, connector is arranged on an end of salvaging body, and joint is threaded with connector.
The utility model is owing to adopt said structure, makes this flexiblely drag for lance and can satisfy simultaneously and the oil pipe of different size and being connected of drilling rod, has the minimizing working strength of workers simultaneously, the high advantage of salvaging efficient.
Description of drawings
Fig. 1 is the flexible lance overall structure schematic diagram that drags for.
The specific embodiment
Shown in accompanying drawing 1: this flexible lance that drags for comprises salvaging body 1, slips 2, spring 3, connector 4, joint 5, described slips 2 is sleeved on the outside of salvaging body 1, spring housing be contained in salvage on the body 1, slips 2 above, connector 4 is arranged on an end of salvaging body 1, and joint 5 is threaded with connector 4.
Operating principle:, check whether each part is intact according to the instrument that the well and the fish internal diameter of different size are selected corresponding specification.Instrument is connected on the drilling rod (or oil pipe), and joint 5 is used for being connected with drilling rod, and connector 4 is used for being connected with oil pipe.After slips being entered salvage in the groove instrument is gone into the well, instrument is near top of fish, turn on pump cyclic flusher top of fish.When instrument arrives desired depth, behind the contact fish, begin slowly to transfer, make instrument enter fish.On carry drilling tool and salvage body slips 2 is swollen, sting tight fish.Carry drilling tool in the continuation, pull fish out.If lift motionless, usefulness be flexible (left-handed), the drilling tool that can reverse proposes the part fish.
