摘要
采用来自胜利油田的岩样,通过水锁效应对岩样渗透率影响的试验研究证实了水锁效应是导致砂砾性低渗气层损害的主要因素之一。然后对油田常用的表面活性剂进行了表面张力的测定,并在此基础上进行了优选,最后对用表面活性剂减轻岩样水锁效应的效果进行了评价试验。
Using low-permeability sands core coming from Shengli oil field ,experimental study was conducted to confirm that aqueous phase trapping was one of the main causes of gas formation damage. The surface tensions of some surface active agents often used in oil field were also measured, and selected. The effects of using surface active agents to alleviate aqueous phase trapping were evaluated.
