摘要
针对油田注水开发过程中井下油管和配套工具普遍存在的腐蚀现象以及所带来的问题,在对胜利油田近年来注水管柱腐蚀状况进行统计分析的基础上,认为注水管柱的腐蚀机理主要是溶解气腐蚀和垢下腐蚀。结合胜利油田在延长注水管柱工作寿命方面所采取的一系列防腐措施,对各种防腐管柱的防腐效果进行了分析。分析结果表明,镍磷镀油管的防腐效果较好且经济,因而注水开发油井推荐采用镍磷镀油管,并建议注水工具全部进行镍磷镀防腐处理。指出注水管柱防腐技术的下一步发展方向是玻璃钢防腐技术和玻璃钢内衬防腐技术。
Considering the erosion occured in downhole strings and tools during water injection and the associated problems, the main reasons for erosion were dissolved gas and scaling erosion based on analysis of the statistical analysis of water injection string in Shengli Oilfield. A series of measures to prolong the string working hour were used in Shengli Oilfleld. All the measures to prevent erosion were analyzed. The analysis results indicate that one type of erosion resistant string was recommended. The future development for erosion control in string was pointed out.
