Industry/University Cooperative Research Activity: Colloidally Induced Fines Migration

研究表明，存在一个临界盐浓度（CSC） 以及盐浓度的临界变化率 敏感性损伤开始。 在研究的第二阶段， 研究人员解释了化学和胶体现象 涉及砂岩水敏性。 除了解释 不同的盐和溶剂产生不同程度的损害， 他正在研究能消除或减少水分的添加剂 砂岩的敏感性。 最后，全面发展 预测渗透率下降的化学和物理模型 由于砂岩的水敏性而引起的水敏性的研究正在继续。

Research has shown that there is a critical salt concentration (CSC) and a critical rate of change in salt concentration at which water sensitivity damage is initiated. In the second phase of the research, the researcher elucidating the chemical and colloidal phenomena involved in sandstone water sensitivity. In addition to explaining the different degrees of damage produced by different salts and solvents, he is investigating additives that will eliminate or minimize water sensitivity in sandstone. Finally, the development of a comprehensive chemical and physical model to predict the permeability decrease resulting from the water sensitivity of sandstone is being continued.
