| Abstract: | 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 optimal conditions were found as follows:the density is 1.0%,the consumption is 0.75 - 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 ... |
