可动凝胶渗流规律研究现状与发展方向

Study situation and development orientation of moveable gel flow through porous medium.

系统分析了可动凝胶与聚合物体系驱油机理和适用条件的区别以及在渗流规律方面的研究现状,总结出了聚合物凝胶一般分类及其特性。提出了研究可动凝胶渗流规律需要分段试验研究流变关系来确定视黏度的变化规律,需要确定视黏度下的相渗规律变化,需要对可动凝胶的整个驱替过程统一考虑,具体研究工作中应该进行分段研究的观点。该研究对指导可动凝胶渗流规律研究和可动凝胶在提高采收率中的应用具有一定的借鉴意义。

Analyzed study situation of oil displacement mechanism of moveable gel and polymeric system,and its applicable condition and flow rule were also studied,summarized general classify and characters of polymer gel.Proposed that it is needed to study flowage relationship by fragment experiment to determine apparent viscosity during study on moveable gel flow through porous medium,and it is needed to determine phase flow changes under apparent viscosity,and account for moveable gel through displacement with fragment experiment view.This study can provide direction to study on moveable gel flow rule and enhanced oil recovery.
