强碱三元复合驱后提高采收率影响因素
INFLUENCING FACTORS OF ENHANCING THE OIL RECOVERY AFTER THE STRONG-BASE ASP FLOODING
摘要
Abstract
In order to optimize the profile-control and flooding system of further enhancing the oil recovery after the strong-alkali ASP flooding,taking Daqing Xingshugang Oilfield as the experimental platform and recoveryq factor,water cut and injection pressure as the evaluating indexes,the experimental research on the oil stimulation effects of further enhanced oil recovery was carried out.The achievements show that the further enhanced oil recovery after the strong-alkali ASP flooding can be realized by injecting the high-concentration polymer solution,polymer/surface binary complex system,weak-base ASP compound system,group of "profile controlling agent + polymer/surface binary complex system" and group of "profile controlling agent + weak-base ternary compound system".The mobility controlling capacity and oil-displaced efficiency are pretty stronger for the combination of "Gel 2 + volume expansion grain + weak-base ASP compound system",and moreover the recovery factor can be enhanced by 10.7％;the input-output ratio of the high-concentration polymer flooding is maximal,so the economic effect is the best.关键词
