摘要
套管采油是无油管采油技术的一种,由于没有油管,节约了生产成本,提高了泵效,减少了杆管偏磨。但是一旦抽油杆柱与套管壁接触,其杆管偏磨更为严重。因此,对套管采油井杆管偏磨机理的研究有着十分现实的意义。
Production in cased well is a new oil production technology developing in recent years. Due to no tubing design,the friction between sucker rods and casing pipes is reduced; the emergency of collapse happened, pump efficiency is developed. But if once friction between sucker rods and casing pipes happened, the result is serious. So,it is important and actually to research mechanism of friction between sucker rods and casing pipes.
