Industry/University Cooperative Research Activity: Colloidally Induced Fines Migration

研究表明，存在一个临界盐浓度（CSC）和盐浓度变化的临界速率，在此条件下，水敏损伤就会发生。在第二阶段的研究中，研究人员阐明了砂岩水敏感性的化学和胶体现象。除了解释不同盐和溶剂造成的不同程度的破坏外，他还在研究能够消除或降低砂岩水敏感性的添加剂。最后，继续开发一个综合的化学和物理模型来预测砂岩的水敏性导致的渗透率下降。

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.
