As development of oil industry is rapid, sleeve pipe is used as the special tubing of the maximum oil well of consumption during oil exploitation, city
Field demand increases year by year, petroleum casing pipe working condition very severe, will not only bear the pressure of casing string generation, but also will
Bear extruding, cracking forces for bringing of bad break power and perforation of ground movement generation etc., therefore petroleum casing pipe comprehensive mechanical property
Require more strictly, existing sleeve pipe is difficult to meet and requires.
Utility model content
The purpose of this utility model is to provide a kind of oil exploitation heat-insulation and heat-preservation composite bushing, to solve above-mentioned background
The problem proposed in technology.
For achieving the above object, this utility model provides following technical scheme：A kind of oil exploitation is compound with heat-insulation and heat-preservation
Sleeve pipe, including sleeve body, described sleeve pipe body right-hand member is provided with external screw thread, and described sleeve pipe body left end is provided with female thread,
Described sleeve pipe body left end outer surface is provided with slot tag, is provided with Upper gasket inside described sleeve pipe body right-hand member, the upper pad
Piece lower end is provided with inner tube, is provided with lower gasket below said inner tube left end, and said inner tube upper end is provided with heat-insulation layer, described
Upper heat-insulation layer upper end is provided with upper interlayer, and the upper interlayer upper end is provided with back-up coat, and the upper back-up coat upper end is provided with
Upper anticorrosive coat, said inner tube lower end are provided with lower heat-insulation layer, and the lower heat-insulation layer lower end is provided with lower interlayer, under the lower interlayer
End is provided with lower back-up coat, and the lower back-up coat lower end is provided with lower anticorrosive coat.
Preferably, triangular in shape inside the upper interlayer and lower interlayer.
Preferably, the upper heat-insulation layer and lower heat-insulation layer are glue and the composite bed of glass fabric.
Technique effect of the present utility model and advantage：Oil exploitation heat-insulation and heat-preservation composite bushing, by external screw thread and
Female thread is screwed, and Upper gasket and lower gasket can increase sealing effectiveness between sleeve pipe and sleeve pipe, and oil is flowed in inner tube
Move, upper heat-insulation layer and lower heat-insulation layer are incubated to inner tube by composite bed, and upper interlayer and lower interlayer inside triangle structure are not
Only there is reinforcement effect, but also heat-insulated effect is played to inner tube, upper back-up coat and lower back-up coat are then substantial to rising
Reinforce, the anticorrosive coat for strengthening the stability of sleeve pipe, upper anticorrosive coat and lower anticorrosive coat plays antiseptical effect to sleeve pipe, extends sleeve pipe
Service life.Oil exploitation heat-insulation and heat-preservation composite bushing, with reasonable in design, easy to use, simple to operate, peace
The advantages of overall height is imitated, can be used with popularity.
