The Evaluation of NHW-1 Type Coated Tubing Abrasion Resistance Performance
Abstract:
The eccentric wear of the sucker rods and tubes has already become the greatest bottleneck restricting the development of oil recovery technology of pumping wells. There is lots of inadaptability of the current control measures. The laboratory study and field tests showed that the NHW-1type coated tubing had a good protection of the rods and tubes of the well pumps. Compared with ordinary tubing, coating can prolong the life cycle of the tubes for more than 2.6 times. At present, the eccentric wear control technology is advanced both at home and abroad.
