摘　　要：针对陕北油田低渗、超低渗地质条件,采用不稳定实验法,研究了SHY-206新型驱油剂注入时机、质量分数以及注入体积倍数与提高原油采收率的关系。结果表明,SHY-206新型驱油剂能够较大幅度提高原油采收率,随着质量分数和注入体积倍数的增加,采收率提高值增加,且注入时间越早,采收率增加值越高。Aiming at the Shanbei oil field by water-flooding,the nonstationary experiment using the surfac-tant made of coal as a displacing agent,natural core,crude oil and formation water of Tuyuke Oilfield is conducted and the effects of injection time,mass fraction and injection volume on oil recovery with water-flooding development are studied. The results show that the displacing agent SHY-206 can greatly enhance oil recovery. As the increase of the injection volume and the mass fraction of the displacing agent SHY-206,the increment of oil recovery is increased. And the earlier injecting,the more effectiveness acquired.
