Abstract
The utility model relates to an oil field casing restoring device, in particular to an oil field casing restoring and truing device. The technical scheme is that the oil field casing restoring and truing device comprises an underground hydraulic cylinder, a connector, a rolling expansion head, a ball, a casing anchor and a hydraulic anchor. The casing anchor is connected with the hydraulic anchor. The lower end of the hydraulic anchor is connected with the underground hydraulic cylinder. The connector is arranged on the lower portion of the underground hydraulic cylinder. The lower portion of the connector is connected with the rolling expansion head, and the rolling expansion head is provided with the ball. The oil field casing restoring and truing device has the advantages of being good in well repairing effect, capable of shortening construction period and saving maintenance cost, high in success rate, capable of delaying the scrapping cycle of a cased well, novel in design, reasonable in structure, strong in casing restoring capacity and good in truing effect, and the anti-external-extrusion capacity of casings after being restored is enhanced.
Description
Technical field
The utility model relates to a kind of sleeve in oil field prosthetic device, and particularly a kind of sleeve in oil field is repaired apparatus for shaping.
Background technology
In oil field development is produced, down-hole casing produces local necking deformation because influenced by the kinds of processes measure to be directed at Casing Failure, oil pump is hung up carry the reduction submergence, influence pump efficiency, the conventional instrument of oil-water well can not normally remove, have a strong impact on the oil field and normally develop, therefore cover change shaping reparation is of great importance to oil field raising output and stable yields.The oil field is to the existing pyriform tube expander of the kind of casing deformation fix tool and technology, the eccentric roller reshaper, third hand tap roller sleeve in oil field is repaired apparatus for shaping, rotation jarring formula sleeve in oil field is repaired apparatus for shaping and explosive shaping etc., the drilling tool of these shaping tools and these shaping tools of driving is affected its intensity because being subjected to the casing size restriction, shaping effect also is affected and limits, and blast damages sleeve pipe.Above-mentioned cover instrument and the technology controlled is owing to being subjected to all multifactor influences to fail to be widely used in production.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of sleeve in oil field to repair apparatus for shaping, and well workover is effective, has shortened the duration, has saved maintenance cost.
Its technical scheme is: comprise down-hole fluid cylinder, connector, roll extrusion rise head, ball, sleeve pipe anchor, hydraulic anchor, the sleeve pipe anchor connects hydraulic anchor, the lower end of hydraulic anchor connects the down-hole fluid cylinder, fluid cylinder bottom, down-hole is provided with connector, the bottom of connector connects the roll extrusion head that rises, and the described roll extrusion head that rises is provided with a plurality of balls.
The beneficial effects of the utility model are: well workover is effective, has shortened the duration, has saved maintenance cost, the success rate height, delayed scrapping the cycle of cased well, modern design, rational in infrastructure, it is strong to repair cover change ability, and shaping effect is good, and the anti-outer extrusion capability of the sleeve pipe after the reparation strengthens.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Among the last figure: sleeve pipe 1, down-hole fluid cylinder 2, connector 3, roll extrusion rise 4, ball 5, sleeve pipe anchor 6, hydraulic anchor 7.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises that down-hole fluid cylinder 2, connector 3, roll extrusion rise 4, ball 5, sleeve pipe anchor 6, hydraulic anchor 7, sleeve pipe anchor 6 connects hydraulic anchor 7, the lower end of hydraulic anchor 7 connects down-hole fluid cylinder 2, fluid cylinder 2 bottoms in down-hole are provided with connector 3, the bottom of connector 3 connects roll extrusion and rises 4, and described roll extrusion is risen and 4 is provided with a plurality of balls 5.
During use, device is placed on sleeve pipe 1 inside, by down-hole fluid cylinder 2 work, drives connector 3 and roll extrusion and rise and 4 rotate, repairing casing, roll extrusion is risen and 4 is provided with ball 5 and can cause damage to casing wall.Well workover is effective, has shortened the duration, has saved maintenance cost, and the success rate height has delayed scrapping the cycle of cased well, and modern design is rational in infrastructure, and reparation cover change ability is strong, and shaping effect is good, and the anti-outer extrusion capability of the sleeve pipe after the reparation strengthens.
