摘要
二元复合驱是控制注水井区含水上升速度,进一步提高采收率的方法,并能有效提高驱油效果,它与三元复合驱相比,具有施工简单、成本低、地层伤害小等优势.二元复合驱技术在油田中的应用逐渐普及,如何通过二元复合驱实现稳油控水,提高油田采出程度成为亟待探究的内容.基于此,通过对XZ油田提高采收率现状及常用技术进行调研与对比,提出目前XZ油田在提高采收率方面面临的挑战,通过室内实验研究了二元复合驱,并在现场取得了一定的效果.
Abstract
Binary composite flooding is a method of further improving oil recovery and can effectively improve oil displacement efficiency.Compared with ternary composite flooding,it has advantages such as reducing formation damage.The application of binary composite flooding technology in oil fields is gradually becoming popular,and how to further improve the recovery degree after binary composite flooding has become an urgent topic to explore.This article investigates and compares the current situation and commonly used technologies for enhancing oil recovery in M Oilfield,and proposes the challenges faced by M Oilfield in improving oil recovery.Through indoor experiments,binary composite flooding has been studied,and certain results have been achieved in the field.
