Abstract
The invention discloses a lining oil tube and a production method thereof. The lining oil tube comprises the following components: 100 parts of ultra-high molecular weight polyethylene, 0.3 parts of an anti-oxidant 1010, 0.2 parts of an anti-oxidant 168, 0.5 parts of nano silica, 2 parts of a calcium stearate dispersant, and 5 parts of glass beads. A production method comprises the following steps: burdening the components according to the above component, stirring a ultrahigh molecular weight polyethylene composition with high speed; extruding the ultrahigh molecular weight polyethylene composition through a special-purpose single screw extruder for the ultrahigh molecular weight polyethylene; cooling the product in a mode, and cutting to obtain the ultrahigh molecular weight polyethylene tube. The performance index of tensile strength and fatigue strength of the produced lining oil tube can reach the requirement, and an embedded pumping rod exceeds the level of a technology-type ultra-high strength rod.
Description
Technical field
The present invention relates to a kind of liner oil pipe and preparation method thereof, belong to petroleum collection accessory technical field.
Background technology
The each oil field of China has substantial amounts of sucker rod to need to change every year, and the old pumping rod changed removes
Because eccentric wear is serious, corrosion flexural deformation is more serious can not repair outside, majority can repair use again；
Old pumping rod reparation is possible not only to realize the repetitive cycling of old pumping rod and uses, and saves substantial amounts of for country
Resource, it is also possible to reducing cost for oil production, the technique of domestic reparation old pumping rod is all through surface clean
After, realized by operations such as aligning, surface hardenings, achieve old pumping rod to a certain extent
Repairing and regeneration, but it has some limitations and shortcoming, such as to eccentric wear, and corrosion old
Sucker rod just cannot be repaired, and this just greatly reduces the repair rate of old pumping rod.
