摘要
实验制备了新型防膨/驱油剂,并且对合成的产品就防膨率、对地层渗透率伤害程度以及降低原油/水界面张力的能力这三个方面的性能进行了评价。结果表明：①对于膨润土/蒸馏水体系,防膨/驱油剂YG-Z的防膨率高达86％以上,对岩心渗透率的伤害只有18％；②在浓度较低的情况下,防膨/驱油剂YG-Z能够将某原油/水的界面张力降低至超低(10^(-3)mN/m)。
The experiment studies the synthetic method and conditions of the YG-Z, and evaluates the synthetic product from three aspects： the rate of anti-swelling and permeability damage degree and deduce the crude oil/ water interface tension ability. The result indicate ①the rate of anti-swelling is above 86% , permeability damage degree is below 18% ,②YG-Z can reduce interface tension of crude oil/water to the super low（ 10^-3mN/ m） level under the concentration is very lower.
