| 摘 要： | 应用胶体化学基本理论和水动力学原理，定量描述微粒沉积、分散和运移的规律，提出了注水过程中微粒分散运移的判定条件，定量分析了控制微粒分散运移的主导力系．既考虑了影响微粒分散运移的水动力学因素，又考虑了影响微粒分散运移的胶体表面化学因素．结果表明，不同油藏条件下，不同微粒表面电学特征对微粒分散运移具有本质上完全不同的影响，同时，注采速度始终是一个十分重要的影响因素．这个理论对水土保持、深层过滤、地下水工程特别是油田注水工程具有十分重要的指导意义．

| Abstract: | he paper describes quantitatively the laws of fines' deposition,dispersing and migration by using the fundamental colloid chemistry theory and principles of hydrodynamics. The conditions for determining fines'dispersing and migration during water flood process are presented. The major force system that controls fines'dispersing and migration is quantitatively analysed. In the presented model,both the hydrodynamical factors and colloidal surface chemistry factors affecting the fines' dispersing and migration were considered. The results indicate that under various formation conditions,different surface electric characteristics have quite different effects on the fines'dispersing and migration. And the injection-production rate has always been an important factor affecting the fines'migration. |
