Description

Thermal-insulator at well opening
Technical field
The utility model is related to a kind of well mouth of oil well protector, and especially a kind of well head insulation for having heat insulation function is filled Put.
Background technology
The oil production method of China is substantially oil pumping method, and this method, which is recovered the oil, to be needed to install wellhead for production, and it is control With the capital equipment of regulation oil well production, due to often there is a small amount of crude oil to fall on wellhead assembly in oil recovery production process, adopt Oily workman will in time clear up and scrub, and add the labor intensity of oil recovery workman, it is dirty that influence production efficiency also results in equipment Dye.On the other hand because the overall body of wellhead assembly is irregular, difficulty is brought to Winter protection, is dismantled again during pump detection and workover Wellhead assembly, this is all unfavorable factor to protection in winter insulation.Producing well day device winter is caused not to be incubated oil recovery production, so in life Problem has been occurred as soon as in production.The most of oil field in the north is produced in mid-later development phase at present.Oil well liquid output amount declines, and moisture content increases Plus, by taking the dawn oil recovery factory of Liaohe Oil Field as an example, full factory's oilwell produced fluid amount composite water cut averagely reaches more than 80%, individual well daily output One ton or so of crude oil, that is to say, that the liquid measure 80% or so of oil well output is water.There is wellhead for production frost in winter when recovering the oil Phenomenon occurs, it is necessary to which boiler car is thawed with steam to scene, and adding production cost influences crude output.According to current north Side recovers the oil two problems at scene, if can develop a kind of structure has an innovation, dismounting is very convenient, with waterproof, prevent fires, have from The well mouth of oil well insulation dress of cleaning function, with regard to that can solve the problem in production of recovering the oil, has accomplished high-efficiency cleaning oil recovery Production.Blank of the wellhead for production without insulation safeguard function has been filled up, has had depth to improving production efficiency and crude output Remote influence.
The content of the invention
The purpose of this utility model is to provide a kind of easy to use and with fire prevention, waterproof and heat insulation function well head and protected Warm device.
To achieve the above object, the utility model thermal-insulator at well opening, including main body cover, main body cover top at least side are set There are upper branch arm cover and the upper valve cover being connected with upper branch arm cover, main body cover bottom at least side is provided with lower branch arm cover and and lower branch arm The connected lower valve cover of cover, thermal-insulator at well opening is integrally made up of internal layer, heat-insulation layer and outer layer successively from inside to outside, outer layer and interior The material of layer is silica gel aramid fiber cloth material, and the material of heat-insulation layer is 1633 retardant cottons.
As a kind of preferred embodiment of the present utility model, thermal-insulator at well opening is additionally provided with out the flap, described to open the flap at least The side of thermal-insulator at well opening is arranged on, and by the sealing device such as nylon adherent buckle lap hermetically and can be taken apart.
As a kind of preferred embodiment of the present utility model, upper branch arm cover and upper valve cover are L-shaped.
As a kind of preferred embodiment of the present utility model, lower branch arm cover and lower valve cover are L-shaped.
As a kind of preferred embodiment of the present utility model, upper branch arm cover and lower branch arm cover on main body cover at least side Provided with opening, the opening is by adjustable device for fastening edge sealing.
As a kind of preferred embodiment of the present utility model, upper valve cover and lower valve cover on main body cover at least side Provided with opening, the opening is by adjustable device for fastening edge sealing.
As a kind of preferred embodiment of the present utility model, be provided with opening at the top of thermal-insulator at well opening, the opening by Adjustable device for fastening edge sealing.
Using the utility model thermal-insulator at well opening, thermal-insulator at well opening integral assembling on well mouth of oil well device and with oil The laminating of well wellhead assembly is tight, and the material of outer layer and internal layer is silica gel aramid fiber cloth material so that thermal-insulator at well opening have fire prevention, Waterproof, insulation and certain self-cleaning function, the material of heat-insulation layer are 1633 retardant cottons so that thermal-insulator at well opening have every Sound, thermal insulation, thermal resistance and the function of insulation.Can by the sealing device such as nylon adherent buckle lap hermetically and take apart open the flap so that well head Attemperator installation and removal more facilitate, and practicality is stronger, it is to avoid Christmas tree frost, less labour cost, Effectively raise oil recovery efficiency and financial cost.
