摘要
杆、管偏磨问题已成为制约抽油机井采油工艺技术发展的最大瓶颈,目前的治理措施存在诸多的不适应性。室内研究及现场试验证明NHW-1型涂层油管对偏磨抽油机井的杆、管有很好的保护作用,该涂层油管与普通油管对比,可延长管杆使用周期2.6倍以上,是目前国内外较为先进的抽油机井杆、管偏磨治理技术。
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—1 type 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.
