摘　　要：利用制备的不同润湿性岩样，系统研究了注入水对这些岩样注水采收率的影响，得到了润湿性对恳东２９块油藏注水采收率的影响规律，即随着岩样水湿性的逐渐增强，注水采收率先逐渐增加后缓慢降低；并得到了使注水采收率最高的恳东２９块油藏岩石润湿指数值，对有效开发恳东２９块稠油油藏具有重要的指导意义。By means of the prepared core samples with different wettability, the effect of injected water on the water injection recovery factor has been studied systematically, and the influential laws of wettability on the water injection recovery factor of Kendong Block 29 reservoir has been obtained, that is, with the gradual increase of water wettability of the core sample, the water injection recovery factor firstly increases gradually, and then decreases slowly. The rock wettability index that can make the Kendong Block 29 reservoir posses the highest water injection recovery factor has also been obtained. This has an important instructive significance for developing the Kendong Block 29 heavy oil reservoir.
