摘　　要：针对西峰长8储层注水压力高,达不到配注要求,结合注入水和采出水特点,对CX型降压增注剂进行了一系列性能评价,如用量、防膨胀效果、乳化解析能力和驱替实验,为增注剂的优选和后期现场运用提供有力帮助,切实解决现场注水困难等问题.In view of the high pressure of water injection of the long 8 reservoir in Xifeng,and the allocation requirement is not satisfied.This paper makes a series of performance evaluation on CX type antihypertensive agent,such as dosage,anti-swelling effect and emulsion resolution ability and displacement experiment,which are combined with the characteristics of injected water and produced water,and provide a strong help for the future optimization and application of augmented injection agent.Of course,some problems of the water injection difficulties in site could be treated well.

关 键 词：低渗储层 降压增注剂 防膨胀效果 乳化解析能力
