摘要
凝胶颗粒调剖技术是近几年出现的一种用于改善高含水期油田开发效果的技术。研究目的在于建立凝胶颗粒调剖的平面径向流数值模拟模型,模拟凝胶颗粒在近井地带的调剖规律。以颗粒渗滤理论为基础,充分考虑凝胶颗粒调剖的膨胀特性、变形运移特性,建立了凝胶颗粒运移的数学模型。将一维径向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,建立了凝胶颗粒调剖的平面径向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。利用所建模型对凝胶颗粒调剖的基本规律以及调剖剂的注入速度、浓度对封堵效果的影响进行了研究。
Gel particle profile-control treatment is a technique to develop high water cut oil field. Purpose of paper is to develop a radial model of gel particle profile-control and to simulate the movement of gel particle near wellbore formation. Gel particle dynamic equation is developed based on filtration theory accouting properties of gel particle： swelling, reforming. Radial 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. By using developed model, analysis of parameters sensitivity is carried out which including gel particle concentration and injecting rate.
