Abstract
The utility model provides a combined rubber plug for combining a casing tube and cementing, comprising a matrix (4), fins (5) and a sealing head (2), wherein, two groups of fins (5) with different diameters are clamped at a groove at the outer wall of the matrix (4) whose extending end is connected with the sealing head (2) through screws and a sealing locking ring (3) is sheathed between the extending end and the sealing head (2) to prevent the liquid inside and outside the casing tube mutually running. The utility model with simple structure not only solves the problem that the rubber plug remains at the casing tube with big diameter.
Description
The utility model relates to the plug of oil field composite bushing well cementation usefulness.
At present, in field produces,, normally two different common plugs of diameter are used in combination by process and remould for satisfying the needs of composite bushing well cementation, the result, the hollow plug that is suitable for the major diameter sleeve pipe can not enter the minor diameter sleeve pipe, and the change that is laid in two kinds of diameter sleeve pipes can not carry out various subsequent jobs through the joint, in addition, handle this hollow plug and also need use to bore and repair instrument and construct again, not only waste of manpower, material resources, and also have certain risk.
The utility model aims to provide a kind ofly can satisfy composite bushing well cementation needs, save the Compounded rubber plug that drills through flow chart.
The utility model comprises matrix (4) and rubber fin (5), two groups of fins (5) that diameter differs are along the axial distribution of matrix (4), and be fastened in the groove of matrix (4) outer wall, the elongated end of matrix (4) has internal thread, matches with the external screw thread of seal head (2).
Advantage of the present utility model is 1, both be applicable to and be applicable to the minor diameter sleeve pipe again by the major diameter sleeve pipe: the phenomenon of 2, having avoided leaving in the major diameter sleeve pipe unnecessary plug or its fragment.3, the self-locking seal structure can be to realizing sealed-for-life inside and outside the sleeve pipe.4, simple in structure, be easy to produce.
Accompanying drawing is a structure chart of the present utility model.
Details are as follows to the utility model below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model comprises matrix (4) and rubber fin (5), if the outer wall of matrix (4) has in groove, two groups of fins (5) that diameter differs are along the axial distribution of matrix (4), and be fastened in the groove of matrix (4), the elongated end of matrix (4) has internal thread, and the external screw thread of seal head (2) matches with it, forms the self-locking seal structure.It is long that major diameter fin (5) is gone up distribute spacing at matrix (4), and the angle that leads is big, and this structure is beneficial to compression, enters the minor diameter sleeve pipe, can not stay remaining plug at the reducing interface, in order to guarantee the sealing inside and outside the sleeve pipe.Between seal head (2) and matrix (4), be set with lock ring (3), and be with joint ring (1) in the groove of on seal head (2), opening (6).The material of matrix (4) can be selected for use and can bore metal.
Claims (4)
1, a kind of Compounded rubber plug, comprise matrix (4) and rubber fin (5), it is characterized in that two groups of fins (5) cover that diameter differs is stuck in the groove of matrix (4) outer wall, along the axial distribution of matrix, the elongated end of matrix (4) has internal thread, matches with the external screw thread of seal head (2).
2, Compounded rubber plug according to claim 1 is characterized in that the spacing of major diameter fin (5) and guiding angle are bigger.
3, Compounded rubber plug according to claim 1 and 2 is characterized in that being with lock ring (3) between matrix (4) and the seal head (2), and is with sealing ring (1) in the groove (6) of seal head (2).
4, Compounded rubber plug according to claim 3 is characterized in that matrix (4) is for can bore metal material.
