前言乳状液的流变性研究工作开展已久,不少人指出,在很多情况下乳状液是属于非牛顿流体的范畴,通常满足幂律定律。考虑到在碱水驱油中,不同的部位会分别形成乳状液驱油和水驱乳状液的两个不同的过程,因此我们分别进行了乳状液驱油和水驱乳状液两类实验,着重观察渗流过程中压差随时间的变化规律、驱替界面现象及乳状液通过孔隙介质后其稳定性的变化,并且将水包油和油包水两类乳状液在渗流过程中所表现出的现象进行比较。通过观 Foreword The research on the rheological properties of emulsions has been carried out for a long time. Many people pointed out that in many cases, emulsions belong to the category of non-Newtonian fluids and usually satisfy the law of power law. Considering two different processes of emulsion flooding and water flooding emulsions in different parts of alkali flooding, we conducted two types of experiments, namely emulsion flooding and water flooding emulsions, focusing on The variation law of pressure drop with time, displacement interface phenomenon and the change of stability of emulsion after passing through pore medium were observed, and the effects of oil-in-water and water-in-oil emulsions on the seepage process were observed Phenomenon to compare.
