| 摘 要： | 暂堵剂能否用于储层堵漏，关键看它是否具有较高的暂堵转向强度，而且在开井生产时能否被油流溶解而自行解堵。通过选用不同型号的树脂，添加合适的分散剂、稳定剂，研制出一种新型的油溶性暂堵剂YRC-1。在静态条件下对该暂堵剂的油溶性、酸溶性和悬浮稳定性进行了研究，并通过岩芯流动实验考察了不同因素对该暂堵剂暂堵率和解堵率的影响情况，给出了该暂堵剂的现场应用情况。研究结果表明：YRC-1暂堵剂具有较好的油溶性、酸不溶性及较好的悬浮稳定性，并具有暂堵率高，暂堵转向效果较好，施工后能自行解除暂堵，保护油气层，现场施工简单等优点。

| Abstract: | There are two constraints for a temporary plugging agent.One is the diverting effect，the other is oil-soluble，the oil soluble，acid soluble and suspension stability of the YRC-1.A new oil soluble temporary plugging agent is studied，and the influence of different factors on the temporary slugging rate and plug removal rate of the YRC-1 is investigated with the core flow experiment.At last，the YRC-1 is applied in oil field.The results show that，the YRC-1 has good oil-soluble and acid insoluble properties，better suspension stability and good diverting effect.In addition，the YRC-1 has many advantages such as high temporary slugging rate，releasing temporary，slugging automatically after operation and operating easily in-situ. |
