通过对胜利油田孤岛采油厂下馆陶单元抽油机井管杆偏磨腐蚀现状调查 ,分析造成管杆偏磨腐蚀的因素主要有井身结构、杆柱受交变载荷、产出液高含水及腐蚀介质等。为此 ,采取环空掺缓蚀剂、下镍磷镀油管及抽油杆、下塑胶抽油杆扶正器及下射流泵措施 ,取得了较好的效果 ,有效延长了抽油机井的检泵周期。 Based on the investigation of the eccentric wear condition of the kiln pipe of Guantao pumping unit under Guodao oil production plant in Shengli Oilfield, the factors that cause the eccentric abrasion of the pipe rod are mainly the well body structure, the rod column is subject to alternating load, Corrosion media. To this end, take annular cavitation inhibitor, the lower the Ni-P coated tubing and sucker rod, under the plastic sucker rod centralizer and the next jet pump measures, and achieved good results, effectively extending the pumping wells pump cycle.
