Current studies suggest that the deviation is caused by the main reason for the eccentric wear of tubing and sucker rod, and the tube column due to a variety of factors caused by bending caused by rod tube eccentric wear also nots allow to ignore, also produced fluid in oil wells are rich in minerals, CO2 and H2S corrosion gas, H + and Cl - and bacteria corrosion medium, the rod tube corrosion, rod tube eccentric wear and corrosion interaction, and the formation of a greater destructive.
So what pipe can be a good solution to the current problem?
A new type of well liner -- ultra high molecular weight polyethylene liner in oil well is to solve the optimal pipeline oil well pipe eccentric wear. Its superior performance is as follows:
1, ultra high molecular weight polyethylene liner in oil well wear resistance and corrosion proof, wax, scaling and other properties in one;
2, ultra high molecular oil within the liner will not produce small holes, cracks, fracture and spalling, no pollution of wells;
3, elastic, adaptation due to lead to changes in oil temperature and oil tube load of tubing deformation, always ensure liner tightly tension in the inner surface of the steel pipe, and keep the seal, without the need for adhesive;
4, ultra high polymer oil well pipe does not change the existing operating process, the next well after not affect the operation, it does not need a special tool;
5, ultra high molecular oil within the liner tube a tough wear-resistant material, oil or cable operation will not damage the lining;
6. The material of the high polymer oil well tubing is inert, which is not easy to occur in other chemical reactions, and has no toxicity.
