Detailed description of the invention
A kind of outer structure wrapping up in insulated tubing described in the utility model, as shown in Figure 1 and Figure 2: wrap up in insulated tubing outside a kind of, comprises the oil pipe of steel oil pipe (steel pipe column), the outer isolation layer of oil pipe, the outer corrosion protective covering composition of isolation layer.The two ends of described oil pipe are for being processed with externally threaded thread segment, and the part near two ends thread segment is two lever pieces, and the part between two lever pieces is interlude.
An outer isolation layer (10) is wrapped up equably at the interlude outer wall of described oil pipe (1); and outside the outer wall of isolation layer (10), wrap up in one deck isolation layer protection steel band (11), finally at the outer anticorrosive heat insulating topping (12) of isolation layer protection steel band (11) outside parcel one deck.At two lever pieces and the box cupling outer wall of the upper 500mm and lower 400mm of the connection box cupling (7) of described oil pipe (1), be provided with the semicircle thermal insulation protection pipe box (5) of two docking.
Now the outer both ends of the surface wrapping up in insulated tubing are oil pipe end face, and the external surface wrapping up in insulated tubing is outward the outer external surface wrapping up in anticorrosive heat insulating topping.
See Fig. 3,4,5.
The interlude outer wall of described oil pipe (1) wraps up the outer isolation layer (10) of one deck equably, and outer insulation thickness is 6mm.Outer isolation layer material therefor is aeroge nano super felt insulation heat-insulating heat-preserving material, and this material has fabulous heat insulation and water-proof function.
Outside the outer wall of the isolation layer (10) of the interlude of described oil pipe (1), wrap up in one deck isolation layer protection steel band (11), this protection thickness of strips is 0.2 ~ 0.4mm, and selected materials is the ordinary steel belts that 0.2mm is thick, 4mm is wide.Steel band adopts the mode be wound around to be entangled in the outer wall of outer isolation layer (10), overlaps 20 ~ 30% between steel band.
The outer anticorrosive heat insulating topping (12) of one deck is wrapped up in again outward outward at isolation layer protection steel band (11) of the interlude of described oil pipe (1); wrapping up in anticorrosive heat insulating protective layer thickness is outward 3 ~ 3.5mm, and this outer anticorrosive heat insulating topping material therefor of wrapping up in is high-density polyethylene composite material.Wrap up in anticorrosive heat insulating topping outward and there is outer anticorrosion and heat insulation, defencive function.
At the process mounting means at two lever piece places of the upper 500mm and lower 400mm of the connection box cupling (7) of described oil pipe (1) be: after oil pipe and tubing coupling are connected at the construction field (site), after prefabricated in advance two semicircle thermal insulation protection pipe box (5) docking are buckled well, by upper and lower for thermal insulation protection pipe box (5) two fastening steel bushings of slip screw thread (8-1), (8-2) tighten, after again two groups of fixed screws (6) of two semicircle thermal insulation protection pipe box middle parts of docking being tightened, finally O-ring seal (9) is installed, whole installation process completes.By their conbined usage, ensure that the realization of the effect of heat insulation of whole tubing string, impact resistance function.Make not destroy during constructing operation heat insulation and other functions of oil pipe simultaneously, utilize conventional tool just conveniently can complete job execution of going into the well.
The feature of described aeroge nano super felt insulation heat-insulating heat-preserving material be high temperature resistant, water resistance good.The thermal loss that heat-insulation and heat-preservation suppression efficiency is high, can suppress high temp objects, effectively suppresses the loss of heat radiation and heat conduction.The product that this nano High Seience Technology Co., Ltd. of materials'use ShaoXing,ZheJiang city produces.
