摘要
从暂堵原理出发 ,研制了一类新型油溶性树脂暂堵剂 ,室内评价结果表明其油溶性好 ,封堵强度高 ,不会对油层造成永久性伤害 ,渗透率恢复值可达 86%以上。
Temporary plugging technology is one of the effective methods for reservoir protection during the workover job. A new oil-soluble resin temporary plugging agent is presented in this paper based on its mechanism. The experiment shows that it is easily dissolve in oil and has better plugging effect. The resortation rate is more than 86% in oil. Therefore it is suitable for workover job to protect formation in oilfield.
