Technical field
The present invention relates to a kind of wear-and corrosion-resistant liner insulated tubing being applicable to the places such as oil extraction in oil field tubing string, underground heat hot well tubing string, oil-gas gathering and transportation and chemical products pipelined.
Background technology
In the actual production process of oil field, commonly used pure light pipe (not adding any heat-insulation and heat-preservation measure) flow string produces at present, and this oil production method exists the problem that crude oil own temperature loses in a large number.On oil pipe anti-corrosive processes, it is typically employed in oil pipe endosexine and coats the solution of anticorrosive paint, owing to the rust dirt not easy-clear in oil pipe is clean and coating is relatively thin, therefore there is the problems such as anticorrosive coat is easy to fall off, service life is short.To solving rod-pumped well rod and tube partial-wear, the technology such as commonly used glass-lined, eccentric abrasion prevention well head, it is big that these technology exist that glass-lined is broken, eccentric abrasion prevention well head operates with workload, the problems such as eccentric abrasion prevention effect is poor.
Summary of the invention
It is an object of the invention to provide a kind of wear-and corrosion-resistant liner insulated tubing, to solve reduce the temperature loss of crude oil crude oil self during shaft bottom flows to well head and improve the technical problem of crude oil fluidised form in the wellbore；The most effectively solve the technical problems such as tubing string rod and tube partial-wear, oil pipe internal corrosion, fouling, wax deposition.
The technical solution adopted in the present invention is as follows:
A kind of wear-and corrosion-resistant liner insulated tubing, fixing setting-in one inner tube 2 in oil pipe 1, and fixing one layer of thermal insulation layer of setting-in constitutes thermal insulation layer 3 between oil pipe 1 and inner tube 2, the length of inner tube 2 is more than oil pipe, the both ends of the surface of inner tube 2 are prominent to be wrapped in outside oil pipe 1 end face, and thermal insulation layer is fixed between inner tube 2 and oil pipe 1.
One layer of sheet steel pipe 4, i.e. thermal insulation layer 3 and sheet steel pipe 4 are installed between thermal insulation layer 3 and inner tube 2 be fixed between inner tube 2 and oil pipe 1.
Described inner tube 2 is thermoplastic high density's composite polyethylene material or ultra-high molecular weight polyethylene composite material, and interior tube thickness is 3.5mm.Thermal insulation layer 3 is aeroge nano super felt insulation heat-insulating heat-preserving material, and insulation thickness is 3mm.Being damaged by thermal insulation layer when the effect of sheet steel pipe 4 is to prevent embedded inner tube, its thickness is 0.5mm.
The invention have the advantage that can effectively reduce downhole crude and hot water flow to the crude oil nature thermal loss of well head from shaft bottom, improves Wellhead crue oil temperature and hot well wellhead temperature；Can thoroughly solve the technical problem such as internal corrosion and post rod and tube partial-wear of oil pipe, reduce rod tube and damage, reduce underground work workload；Can reduce the frictional resistance between rod-pumped well rod tube, reduce oil pumper load and reach more significant power savings；It is finally reached energy-saving and emission-reduction, reduces rod tube damage, reduce underground work workload, be substantially reduced cost of oil production.
