Abstract
The utility model relates to an oil well sleeve pipe, including the casing main body, the upper and lower both ends of casing main body all are equipped with the hickey, are equipped with the adhesion coating of nai high -temperature glue on the outer wall of casing main body, are equipped with the silica sand layer on the outer wall of the adhesion coating of nai high -temperature glue. The utility model discloses an oil well sleeve pipe structural design is reasonable, is equipped with on the outer wall of casing main body through the fixed silica sand layer of the adhesion coating of nai high -temperature glue, increases roughness, can make well cementation cement and sleeve pipe combination firmly be in the same place, has strengthened and has prevented scurrying performance, long service life.
Description
Technical field
The utility model relates to a kind of oil well casing.
Background technology
Often oil well casing can be used at present in oil exploitation oil well; oil well casing is used for the shutoff borehole wall; need after complete sleeve pipe to reinforce from well head high-pressure injected water mud under oil well; but the sleeve surface on existing market is very smooth; easily occur altering groove problem in separate zone production; make oil well not fuel-displaced or few fuel-displaced, affect oil extraction greatly.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of oil well casing.
Oil well casing of the present utility model, comprises casing main body, and the two ends up and down of described casing main body are equipped with hickey, and the outer wall of casing main body is provided with high-temperature plastic adhesion coating, and the outer wall of high-temperature plastic adhesion coating is provided with silicon sand layer.
Compared with prior art the beneficial effects of the utility model are: oil well casing reasonable in design of the present utility model, the outer wall of casing main body is provided with by the fixing silicon sand layer of high-temperature plastic adhesion coating, increase surface roughness, cementing concrete and sleeve pipe can be made to combine firmly, enhance to put and alter performance, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of oil well casing described in the utility model embodiment.
In figure:
1, casing main body; 2, hickey; 3, high-temperature plastic adhesion coating; 4, silicon sand layer.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of oil well casing, comprises casing main body 1, and the two ends up and down of described casing main body 1 are equipped with hickey 2, and the outer wall of casing main body 1 is provided with high-temperature plastic adhesion coating 3, and the outer wall of high-temperature plastic adhesion coating 3 is provided with silicon sand layer 4.
Oil well casing reasonable in design of the present utility model, the outer wall of casing main body is provided with by the fixing silicon sand layer of high-temperature plastic adhesion coating, increases surface roughness, cementing concrete and sleeve pipe can be made to combine firmly, enhance to put and alter performance, long service life.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
