| 摘 要： | 针对长6油层组地质条件及储层物性,通过室内模拟实验,研究了长庆2号表面活性剂对驱油效果的影响,使用不同渗透率的天然岩心进行水驱后表面活性剂驱油实验,分析了驱替过程中的压力、采收率及含水率的变化规律。结果表明:水驱后采用表面活性剂驱可以有效地提高原油采收率,平均提高采收率8个百分点左右。

| Abstract: | Accodding to the geological conditions and physical parameter in the Chang 6 oil-bearing formation,the Changqing No.2 surfactant is used to research on the effect of surfactant flooding in chang6 reservior through physical simulations in laboratory using natural core with average permeability range from 0.92 to 1.47×10-3 μm2.The rules of pressure,recovery and water cut variation during displacement are analyzed.It is shown that the surfactant flooding could improve oil recovery effectively after water flooding,the average oil recovery is about 8 %. |

| Keywords: | Surfactant permeability Chang 6 oil-bearing formation recovery |
