Abstract
The utility model relates to an oil exploitation pipeline, and in particular relates to a novel heat preservation sleeve pipe capable of being widely used for the process of oil exploitation. The technical scheme adopted by the utility model is as follows: the oil exploitation pipeline mainly consists of a sleeve pipe body, a heat preservation layer and a protective cover, wherein the heat preservation layer is paved outside the sleeve pipe body, and the outer side of the heat preservation layer is additionally provided with the protective cover for preventing the heat preservation layer from being damaged. The oil exploitation pipeline has the benefit effects that for all the oil wells, the higher the temperature of the crude oil at a well opening is, the more preferable transportation and treatment of the crude oil can be carried out, and the geothermal energy of the crude oil can be effectively used by the heat preservation sleeve (oil) pipe. For a water injection well, the higher the temperature of the injected water is, the more effective the water injection is, so that the heat preservation sleeve (oil) pipe further plays a role in heat preservation.
Description
Technical field
The utility model relates to a kind of oil exploitation pipe fitting, particularly a kind of novel heat insulation sleeve pipe that is widely used in the oil exploitation process.
Background technology
At present, in oil exploitation,, when crude oil is made progress lifting process by the stratum in, exist thermal loss owing to there is geothermal gradient.If can causing viscosity of crude, viscous crude increases, 10 ℃ of the every reductions of temperature, and viscosity doubles, and viscosity increases, and is shortened or stopping production the production cycle; If the crude oil that the content of wax is higher, temperature reduces, and wax deposition speed improves, and directly influences speed of production, increases the operation number of times, and operating cost increases; If during the heavy crude heat extraction steam injection, the upper sleeve heat waste causes heat energy efficiency to reduce greater than following parts casing pipe.
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 heat insulation sleeve pipe is provided, and reduces thermal loss, improves oil recovery efficiency.
Its technical scheme is: mainly be made up of sleeve pipe, insulation layer and protective sleeve, described sleeve pipe is covered with insulation layer outward, adds the protective sleeve that prevents that insulation layer from damaging in the outside of insulation layer.
The top of above-mentioned insulation layer is provided with the support ring of the concentricity that is used to keep insulation layer and sleeve pipe.
The lower end of above-mentioned insulation layer is provided with the reinforcement groove that is used to increase protective sleeve longitudinal strength and positioning supports ring.
Above-mentioned sleeve pipe is provided with reserves section and soaking zone, and the sleeve pipe in the soaking zone outside is covered with insulation layer outward, adds the protective sleeve that prevents that insulation layer from damaging in the outside of insulation layer; Described reservation section and soaking zone flexibly connect through pin.
Be provided with back-moving spring in the above-mentioned pin.
Above-mentioned insulation layer is that two semicircles watt shape insulation layer is formed.
The beneficial effect of the utility model is: for all oil wells, the well head crude oil temperature is higher, helps the conveying and the processing of crude oil more, and muff (oil) pipe can effectively utilize the geothermal energy of crude oil.For water injection well, the coolant-temperature gage of injection is higher, and water filling is effective more, and muff (oil) pipe also plays insulation effect.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is structure sketch mapes of the insulation layer of the utility model;
Accompanying drawing 3 is the enlarged drawings at the pin position of the utility model;
Among the last figure: sleeve pipe 1, insulation layer 2, support ring 3, reinforcement groove 4, pin 5, back-moving spring 6, protective sleeve 7, reservation section A and B, butt joint box cupling C.
The specific embodiment
Embodiment 1: the utility model mainly is made up of sleeve pipe 1, insulation layer 2 and protective sleeve 7, is covered with insulation layer 2 outside the described sleeve pipe 1, adds the protective sleeve 7 that prevents that insulation layer from damaging in the outside of insulation layer 2.
Embodiment 2: combine accompanying drawing 1-3; The utility model is done further to describe; The utility model mainly is made up of sleeve pipe 1, insulation layer 2 and protective sleeve 7; Sleeve pipe 1 is provided with reserves section A, B and soaking zone, is covered with insulation layer 2 outside the sleeve pipe 1 in the soaking zone outside, adds the protective sleeve 7 that prevents that insulation layer from damaging in the outside of insulation layer 2; Described reservation section and soaking zone flexibly connect through pin 5.
Wherein, the top of insulation layer 2 is provided with the support ring 3 of the concentricity that is used to keep insulation layer and sleeve pipe; The lower end of insulation layer 2 is provided with the reinforcement groove 4 that is used to increase protective sleeve longitudinal strength and positioning supports ring; With reference to accompanying drawing 3, be provided with back-moving spring 6 in the pin 5, under non-destructive situation, be difficult to take off behind the snapping,
A, B are the reservation section of warp to site operation in the accompanying drawing, and length is that 300-500 does not wait, and C is the butt joint box cupling.In work progress, tong blocks A, dock screw thread, box cupling the B position.
Insulation layer is mended to fill out by two semicircles watt shape insulation layer later stage and is formed; Is folding at its diameter to the one side that bursts at the seams; Another side is dowel fixes (with reference to Fig. 2); Its principle is: after butt joint box cupling C and screw thread butt joint construction completion, two semicircle watt shape insulation layers are buckled on the soaking zone, and its effect is: one, soaking zone is incubated; Two, prevent that the insulation layer (cover) on the sleeve pipe from axially sliding in the process of going into the well.The effect of support ring is the concentricity that keeps protective sleeve and sleeve pipe, and is even to ensure each position insulation layer thickness of circumference.Certainly, the utility model is not only applicable to sleeve pipe, goes for oil pipe yet.
