摘　　要：该文通过试验对起泡剂、稳泡剂进行了筛选,并确定了其使用浓度。通过用并联含油和含水单岩芯泡沫分流驱替实验,对泡沫液暂堵分流性能开展评价与研究,形成了适合中、高含水油井的泡沫酸酸化工艺。在江苏CB油田推广应用,增产效果显著。同时也为类似地区泡沫液暂堵分流性能评价和应用提供借鉴。In this paper,the foaming agent and foam stabilizer were screened out,and their use concentration was determined.The parallel oil and aqueous foam diversion core displacement experiment was carried out to evaluate the performance of foam temporary plugging and diversion.In the end,the acidification process for medium and high water cut oil wells was formed.Application of the acidification process in CB oil field in Jiangsu has obtained significant effect on increasing production.
