西峰油田注水压力升高原因及对策

REASONS OF INJECTION PRESSURE RISE AND PREVENTIVE MEASURES IN XIFENG OILFIELD

从西峰油田长8和安塞油田长6储层特征、长8注水伤害机理室内试验分析和长8现场挤注解堵剂效果,从三方面研究分析了注水压力高的原因,找到降低西峰油田回注水的有效方法。适合于西峰油田能有效降低水源水注水压力的助剂——FH-01解堵剂及降低采出水注水压力的助剂,缓解、修复被破坏的地层能够大幅度提高驱油效率。

Based on the features of Xifeng oilfield Chang 8 reservoir and Ansai oilfield Chang 6 reservoir,the laboratory anal-ysis of water injection damage mechanism and the results of injec-tion blocking remover in Chang 8 reservoir,the reasons of injec-tion pressure rise were analyzed,and the effective methods of re-ducing injection pressure were found out in Xifeng oilfield.FH -01 blocking remover suited for Xifeng oilfield was developed,it could reduce injection pressure and improve oil displacement effi-ciency.
