摘要
王庄油田蒸汽驱现场常用SL-2型黏土稳定剂进行防膨。通过不同浓度、温度系列筛选及岩心流动实验,对其性能进行了评价。确定了最佳应用质量分数为1.0%,注入体积0.75～1.0 PV时,SL-2防膨率83.0%,岩心渗透率保留率达87%以上,防膨有效期达50 PV。实验表明,SL-2防膨剂属耐温、高效型防膨剂,非常适合强水敏油藏开发使用。
Wangzhuang oilfield＇s steam flooding often uses SL-2 clay stabilizer for anti-swelling.Through screening experiments on density, temperature range and core flow experiment, the optimalconditions were found ing effect reaches top as follows, the density is 1.0 %, the consumption isO. 75 - 1.0 PV, anti-swelling effect reaches top value with the permeability retention rate above 87% and effect-period of 50 PV. The experimental results show that SL-2 clay stabilizer is very suitable to anti-swelling for high water-sensitive oilfields with hot resistance and high efficiency.
