Abstract
The utility model relates to an oil well casing repair tool, in particular to a novel oil well casing shaper. The technical proposal is as follows: the novel oil well casing shaper is composed of an upper joint, a shaping head and a steel ball; concave annular grooves are formed on the outer conical surface of the upper joint and the inner conical surface of the shaping head; the steel ball is mounted in the concave annular grooves of the upper joint and the shaping head so that the upper joint and the shaping are matched with each other; and more than two spiral flow guide grooves are formed on the surface of the shaping head. The novel oil well casing shaper is capable of well protecting the deformed part of the casing, reducing replacement of the oil-well pump and the downhole tool, improving the working efficiency and increasing the yield of the crude oil.
Description
Technical field
The utility model relates to a kind of oil well casing fix tool, particularly a kind of novel casing shaping device.
Background technology
Growth along with the oil-water well exploitation time limit; And engineering factor and influence of geological factors; Casing Failure damage in various degree will occur and influence production; Sleeve pipe bears the reservoir stress that changing and the inside and outside extruding force of fluid all the time in the down-hole, produce necking down and local distortion, has a strong impact on the replacing of oil well pump and downhole tool.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of novel casing shaping device is provided, and there is better protect at the casing deformation position, reduces the replacing of oil well pump and downhole tool, increases work efficiency.
Its technical scheme is: mainly be made up of top connection, shaping head, steel ball; The inner conical surface of the male cone (strobilus masculinus) of top connection and shaping head is provided with the spill annular groove; Through steel ball is installed it is cooperatively interacted in the spill annular groove of top connection and shaping head, the surface of described shaping head is provided with the spirality guiding gutter more than two.
The beneficial effect of the utility model is: this instrument can have better protect to the casing deformation position, reduces the replacing of oil well pump and downhole tool, increases work efficiency, and promotes crude output.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: top connection 1, shaping 2, steel ball 3, spirality guiding gutter 4.
The specific embodiment
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly is made up of top connection 1, shaping 2, steel ball 3; The inner conical surface of the male cone (strobilus masculinus) of top connection 1 and shaping 2 is provided with the spill annular groove; Through steel ball 3 is installed it is cooperatively interacted in the spill annular groove of top connection 1 and shaping 2, the surface of described shaping 1 is provided with the spirality guiding gutter 4 more than two.
The utility model impacts without the handling drill string, only needs rotary drill column and makes instrument produce downward jarring force, and there is better protect at the casing deformation position; On the shaping inner hole wall spill annular groove is arranged, steel ball is housed and is pinned and outer scurrying by screw, steel ball is connected as a single entity top connection and shaping head; A top connection and shaping contact surface is fitted to each other through the spill annular groove, can rotate a tubing string and take place to knock for three times, and the surface of shaping head is provided with the spirality guiding gutter more than two; Can circulation well cleanup, this instrument can have better protect to the casing deformation position, reduces the replacing of oil well pump and downhole tool; Increase work efficiency, promote crude output.
