摘　　要：安塞油田王窑区块开发时间长，已进入中高含水期，常规水驱提高采收率难度大，措施增产效果差。因此，开展表面活性剂驱油技术研究，优选TL-37复合驱油剂，进行合理驱替参数研究，实验表明该驱油剂具有较强的乳化活性和降低界面张力的能力，可用于矿场先导试验。The Wangyao block of AS oilfield has been developed for a long time and entered the middle to high water cut stage, and it is difficult to improve the recovery rate through the conventional water drive method, and the effects of production stimulation measures are poor. Therefore, it is important to perform technical research into surfactant drive oil production, optimally select the TL-37 composite oil driving agent and carry out the study to identify the reasonable displacement parameters. Experiments show this type of oil driving agent has comparatively high emulsifying activity and the ability to reduce interface tension, and can be applied in the field pioneering experiment.
