Description
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

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.
