Abstract
The utility model discloses a low temperature resistance oil pipeline, which comprises a pipe body and an outer casing which is embedded and sleeved outside the pipe body in a sealed mode. The outer casing is connected with an inlet and an outlet of a steam hose. In the utility model, a fluid heat preservation and temperature rising mechanism formed by the steam hose and a sealing system is adopted to replace a heat insulation layer in the prior art, and the defects that the existing oil pipeline is inconvenient to connect and cannot be used in the low-temperature environment are overcome. After high-pressure steam is filled through the steam hose, the pipe body can always keep at a certain temperature through heat transfer, so that conveying of high viscosity fluid in the low-temperature environment is realized. Relative to a mode of inputting the high-pressure steam into an oil well, the low temperature resistance oil pipeline has the characteristics of simpleness, convenience, low cost and better effect.
Description
Technical field
The utility model relates to a kind of oil pipeline, particularly a kind of oil pipeline that can use under low temperature environment.
Background technology
The oil exploitation environment is relatively more abominable usually, in order to adapt to the requirement of varying environment, discloses multiple oil well head construction pipeline at present.Under low temperature environment, fluid viscosity in the pipeline increases, it is big that flow resistance becomes, mobile variation, thereby increased the difficulty of construction operation, when carrying out the operation of the less or intermittent delivery fluid of flow, even the pipeline inner fluid can occur and freeze, the situation of constricted flow makes that pipeline can't normal operation.The oil well head construction pipeline that under low temperature environment, uses at present, being generally the many thick-walled seamless steel pipes that are uneven in length is cascaded with connector, the outside method of parcel insulation layer that adopts is incubated pipeline, but this kind pipeline result of use under low temperature environment is bad, occur the situation freezing to be obstructed easily, influence the progress of work and efficient.In order to address the above problem, people often will inject high steam in oil well in low-temperature construction, borehole fluid is heated up, normally carry out thereby guarantee to construct, but need to increase a cover simultaneously and inject the high steam construction auxiliary equipment, expend a large amount of manpower and materials, bring the deuce to pay, influence the progress of work to construction.
The utility model content
The purpose of this utility model provides a kind of low temperature resistant oil pipeline easy to connect, has simple in structure, safe and reliable characteristics.
For achieving the above object, by the following technical solutions:
A kind of low temperature resistant oil pipeline comprises that body and sealing are nested in the overcoat outside the body, the described outer import and export that are connected with steam hose that put.
Preferably, overcoat described in the utility model and body seal by stuffing box.
Preferably, for the ease of the installation and removal of steam hose, steam hose described in the utility model is connected by fast connector with overcoat.
Further, a back-up ring and two oil immersion asbestos packings are housed in the stuffing box described in the utility model, described oil immersion asbestos packing compresses by gland.
Optionally, adjacent two low temperature resistant oil pipelines can connect by the union joint, thereby realize connecting fast and dismounting.
The fluid insulation that the utility model adopts steam hose and sealing system to form heats mechanism and has replaced insulation layer of the prior art, has overcome the defective that existing oil pipeline can not use under low temperature environment; After described steam hose feeds high steam, heat in the high steam reaches body by the heat transmission, thereby make body can remain certain temperature, phenomenon appears freezing when effectively preventing under low temperature environment the transfer of highly viscous fluid, guarantee normal operation and the normal programming and the efficient of pipeline, be implemented under the low temperature environment conveying high viscosity fluid; With respect in oil well, importing high steam, have simple and convenient, safe and reliable, cost is low, the characteristics of quick and better effects if.In addition, adjacent two pipelines can connect fast and dismounting by the union joint, overcome existing oil pipeline and connect inconvenient problem, and steam hose also can be connected by fast connector with overcoat, and easy installation and removal has guaranteed efficiency of construction.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the assembling drawing of analysing and observe of the described low temperature resistant oil pipeline of the utility model embodiment.
Among the figure:
1, body; 2, overcoat; 3, stuffing box; 4, steam hose; 5, back-up ring; 6, oil immersion asbestos packing; 7, gland; 8, fast connector; 9, union joint.
The specific embodiment
Below in conjunction with accompanying drawing, further specify the utility model by embodiment.
As shown in Figure 1, low temperature resistant oil pipeline described in the utility model, comprise body 1 and seal the overcoat 2 that is nested in outside the body 1 by two ends stuffing box 3, be connected with the import and export of steam hose 4 on the described overcoat 2, wherein, a back-up ring 5 and two oil immersion asbestos packings 6 are housed in the described stuffing box 3, and described oil immersion asbestos packing 6 compresses by gland 7; Described steam hose 4 is connected by fast connector 8 with overcoat 2, is provided with the connection that union joint 9 is used for two pipelines at described low temperature resistant oil pipeline two ends.
In the course of the work, inject high steam by steam hose 4, be filled between body 1 and the overcoat 2, heat in the described high steam reaches body 1 by the heat transmission, then reach fluid by body 1, thereby effectively prevent fluid Yin Wendu from crossing low and phenomenon occurs freezing, make fluid unimpeded, guarantee the pipeline normal operation, stuffing box 3 is connected by fast connector 8 with steam hose 4, can connect by quick union joint 9 between two depot sidings, thereby make that use of the present utility model is more convenient; High steam directly injects by steam hose 4, with respect to directly high steam being injected oil well, has omitted expensive auxiliary equipment, thereby has reduced cost and more simple and convenient, and result of use is also better.
Claims (5)
1. a low temperature resistant oil pipeline is characterized in that, comprises that body and sealing are nested in the overcoat outside the body, the described outer import and export that are connected with steam hose that put.
