|
摘要
为了适应高温高盐裂缝型油藏的复杂地层情况,研究了一种AM/AMPS(丙烯酰胺/2-丙烯酰胺基-2-甲基丙磺酸)耐温抗盐凝胶堵水调剖体系。确定了最优配方为1. 0%AM/AMPS+0. 1%乌洛托品+0. 1%对苯二酚+0. 3%硫脲+0. 5%PA纤维,考察了该凝胶体系的成胶时间、成胶强度和脱水率,并探讨了该体系的热稳定性和抗盐性。实验结果表明:该凝胶体系具有很好的耐温抗盐性能,在140℃、模拟油田地层水环境中成胶时间大于15 h,凝胶强度保持在G级(目测代码法),120 d脱水率小于2%。岩心封堵实验结果表明,该凝胶体系堵水率达到99. 70%以上,堵油率小于6. 00%,具有优良的选择性。现场应用中取得了良好的堵水调剖效果。该凝胶体系为高温高盐裂缝型油藏的高效开发提供了技术支持,值得推广应用。
In order to adapt to the complex formation status of fractured reservoirs with high temperature and high salt,an AM/AMPS( acrylamide/2-acrylamido-2-methylpropanesulfonic acid) heat and salt resistant gel water plugging and profile control system was studied. The optimum formulation of 1.0% AM/AMPS+ 0.1% urotropine+0. 1% hydroquinone+0.3% thiourea+0.5% PA fiber was determined; the gelling time,gelling strength and dehydration rate of the gel system were investigated; and the thermal stability and salt resistance of the system were also discussed. The experimental results show that the gel system has good resistance to heat and salt; in the environment of simulated oilfield formation water at 140 ℃,the gelling time is more than 15 h,the gel strength is maintained at grade G( visual code method),and the dehydration rate is less than 2% in 120 days. The core plugging experiment results show that the water plugging rate of the gel system is more than 99.70%,the oil plugging rate is less than6. 00%,showing an excellent selectivity. Good water plugging and profile control effect has been achieved in field application. The gel system provides technical support for efficient development of high temperature and high salt fractured reservoirs,worthy of promotion and application.
