1, Of ultra-high molecular paraffin oil lined pipe
Ultra-high-molecular-lined tube wells have low friction coefficient, anti-fouling, self-lubricating characteristics. By friction coefficient test showed that the well liner ultra-high molecular friction coefficient from 0.07 to 0.11, equivalent to friction between the ice and the ice. Wall surface is very smooth, reducing the frictional resistance of liquid flow in a pipe produced, reduce the risk of liquid wax in the tubing.
2, ultra-high molecular well liner abrasion resistance
Ultra-high molecular well liner pipe compared with other materials have good wear resistance characteristics. After processing, ultra-high molecular well liner wear resistance is still higher than normal molecular weight polyethylene pipe more than 10 times. By the Beijing Research Institute of Nonferrous Metallurgy Design "research into the plastic tube wear test reports" can be seen: the following four pipes of different materials in the same diameter, flow rate, test materials, test concentrations, ultra high molecular wells liner wear is common steel pipe times.
3, ultra-high molecular wells lined pipe corrosion
OCTG has excellent chemical resistance to resistance, in addition to strong oxidizing acid, at a certain temperature and the depth of the ability of various corrosive media such as acids, bases, salts and organic media (except tea solvent). At 20 ℃ and 80 ℃ two temperatures, through the 80 kinds of organic solvent to soak 30 days, without any abnormal appearance now. This feature makes the wells containing the various chemical agents on the tubing to reduce corrosion and extend the life of the tube there.
4, high temperature oil well pipes
Poor heat resistance of ordinary polyethylene pipe for conveying cold water, cross-linked polyethylene pipe can transport 90 ~ 110 ℃ water. And because of its relative molecular weight of ultra-high molecular tube, difficult to move the molecular chain, does not flow when melted, translucent rubber-off high viscoelastic state, experiments show that at temperatures up to 150 ~ 200 ℃ still maintain the original shape. So wash well at high temperatures, the ultra-high molecular lined composite pipes can still maintain the original shape.
ASTM E213 OCTG Steel Pipe can be well applied in the following types of oil wells: (1) Production wells: for wear and corrosion severe migraine tubing, rod failure rate, fouling wells; (2) injection wells: for corrosion, scaling serious injection wells; (3) offshore wells: long life to reduce the cost of offshore oil; (4) Corrosive gas: anti-H2S and CO2 gas corrosion; (5) pipes: not applicable after downhole corrosion and wear of the lining can be used as a serious old pipe pipeline.
