Abstract

A self-sliding type underground fishing tool for oil, water well underground water distributors, production distributors, blanking plugs and the like in the process of oil exploitation comprises a rope cap (1), a weighting rod (2), an outer cylinder (3), a connecting rod (4), a compression spring (5), a fishing head (6), a positioning shearing pin (7), a sliding ball (8), an upper groove (9) of the outer cylinder and a lower groove (10) of the outer cylinder, wherein the rope cap (1), the weighting rod (2) and the outer cylinder (3) are sequentially connected, the connecting rod (4), the compression spring (5) and the fishing head (6) are sequentially connected, the fishing head (6) is provided with the positioning shearing pin (7), the sliding ball (8) is embedded into the fishing head (6), the fishing tool can be easily introduced into the fished underground appliance by the natural weight of the fishing tool, the positioning shearing pin on the fishing head is smoothly abandoned when the fishing tool is not moved, the field operation is very convenient, and the abandoning, provides conditions for secondary fishing and avoids the accidents of falling and blocking caused by unmovable fishing during fishing.

Description

A kind of from slidingtype down-hole fishing tool
Technical field
The utility model belongs to special-purpose fishing tools such as oil, well downhole water flow regulator, production mandrel, blanking plug in the oil exploitation process, specifically, is a kind of from slidingtype down-hole fishing tool.
Background technology
The down-hole fishing tool is to be used for special-purpose fishing tools such as oil, well downhole water flow regulator, production mandrel, blanking plug, because the downhole tools that drags for is subjected to factors such as fouling, burn into sand card to cause, block fishing tool, there is the fishing tool problem of can not giving up, fishing tool commonly used at present is a slip-type, need to squat to hit and introduce the downhole tools that drags for, exist the mushroom head of the utensil that drags for to be hit distortion, downhole tools of being pulled out and fishing head are very inconvenient in the ground dismounting.
The salvaging of water injection well downhole water flow regulator is fallen, the card accident takes place frequently, and fishing tool and steel wire are fallen into the well that causes workover treatment in the well and taken place also the time.Carrying out oil, well downhole tools when salvaging, can often carry motionless, load and fishing tool and steel wire all be fallen into accident in the well, causing final workover treatment economic loss above tensile strength of wire.
Summary of the invention
It is a kind of from slidingtype down-hole fishing tool that the purpose of this utility model is to provide, the project organization that ancient unit of weight, equal to 1/24 liang slip is rolled in employing has solved the problem that head is easily gone into and can be given up of dragging for, chance is carried when motionless the raising integrally instrument and can be given up, fishing tool can be broken away from dragged for downhole tools, stopped to fall the card accident in the salvaging process.
The utility model is achieved in that and comprises rope socket, weighted lever, urceolus, connecting rod, compression spring, drags on head, position shearing pin, advance ball, the urceolus groove under groove, the urceolus, rope socket, weighted lever, urceolus connect successively, connecting rod, compression spring, drag for head and connect successively, drag for the position shearing pin is housed on the head, advance ball is bumped into and drags in the head.
Advance ball at least more than one.
Be respectively equipped with on the urceolus groove 10 under groove 9, the urceolus on the urceolus.
Advantage of the present utility model is: when salvaging downhole water flow regulator, blanking plug, can easily introduce by the natural weight of fishing tool and be dragged for downhole tools, chance is carried and is cut off the position shearing pin that drags on the head when motionless and give up smoothly, execute-in-place is very convenient, the realization function of giving up, salvaging for secondary provides condition, stopped to carry when salvaging motionless cause, the card accident, repair operating cost in the saving.
Oil, the special-purpose fishing tool of well downhole tools have taken into full account applicability in design and have leaned on property, dragging for head by traditional slip-type changes steel ball ball slidingtype into and drags for head, introducing power minimum used when being dragged for downhole tools, good reliability after dragging for, be difficult for slippage, meet carry motionless, can give up when load surpasses tensile strength of wire with fishing tool with dragged for downhole tools and separated.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
As shown in drawings, from slidingtype down-hole fishing tool comprise rope socket 1, weighted lever 2, urceolus 3, connecting rod 4, compression spring 5, drag for 6, groove 10 under groove 9, the urceolus on the position shearing pin 7, advance ball 8, urceolus, rope socket 1, weighted lever 2, urceolus 3 connect successively, connecting rod 4, compression spring 5, drag for 6 and connect successively, drag on 6 position shearing pin 7 is housed, advance ball 8 is bumped into and drags in 6.
Advance ball 8 at least more than one.
Be respectively equipped with on the urceolus groove 10 under groove 9, the urceolus on the urceolus 3.
Position shearing pin 7 is fixed on and drags on 6, and 3 advance balls 8 are bumped in dragging for a part of 6.When salvaging, the natural weight that is dragged for downhole tools mushroom head rest fishing tool top with drag for 6 part and do relative motion and introduce and drag for 6,3 advance balls sliding 8 are gone on the urceolus groove 9 spaces and are abdicated, on carry fishing tool and pin and to be dragged for downhole tools mushroom head, chance is carried and is cut off a position shearing pin 7 that drags on 6 when motionless, and 3 advance balls 8 slipped under the urceolus groove 10 again and realized giving up this moment.
From slidingtype down-hole fishing tool, mentality of designing, method are tested repeatedly through the scene and theoretical demonstration forms, especially utilize the principle of confounding function to solve easily to drag for and can give up problem, its structure design advantages of simple, can be widely used in outer salvaging modes such as oil, well downhole water flow regulator, production mandrel, blanking plug, belong to the economic and practical product.
