摘要
以渗滤理论为基础,考虑凝胶颗粒调剖的膨胀特性、"变形虫"特性以及与残留聚合物的协同作用特性,建立了凝胶颗粒运移的数学模型;将渗流模型与凝胶颗粒运移模型、储层参数动态变化模型进行耦合,建立了聚驱后凝胶颗粒调剖的单井流固耦合数值模拟模型,采用迭代耦合方式对该模型进行了求解,并对所建模型进行了参数敏感性分析.
Gel particle profile-control is a effected treatment to develop oil field after polymer flooding. Study on this treatment is mainly in laboratory. Design of assisgnment mainly depends on experiment, lack of numerical simulation method. And there is no report about numerical simulation of this treatment. Gel particle dynamic equation is developed based on filtration theory accouting properties of gel particle: swelling, reforming and polymer effect. Injecting model of gel particle profile-control is developed by coupling dynamic equation, percolation equation and reservoir poroperm parameters changing equation. An explicit solution is used to solve the model. At last, analysis of parameters sensitivity is carried out, proves the model is reliable.
