陈庄稠油油藏深部调驱技术研究与应用

Research and application of deep-profile control and displacement technology in Chenzhuang Oilfield

陈庄油田是一个具继承性发育的受基岩古地形控制的披覆构造稠油油藏。1992年投入全面开发,近年来部分油井含水快速上升、平面水淹严重,加之油层纵向上水驱不均,常规普通调剖效果变差。针对这一问题,阐述了一种新型的提高采收率决策技术——DAM决策技术,应用这一技术研究了陈庄油田的渗透率分布规律和水驱规律及陈庄油田调驱措施的选井、选剂、选量;研究了适合稠油油藏的高、中、低强度的调驱剂系列,特别是研究了一种具有深部调剖和驱油双重作用的调驱剂;研究了适合稠油油藏的调驱剂组合与设置方式,包括高、中、低强度调驱剂的注入顺序、用量分配及不同调驱剂在地层中放置的位置对堵水和驱油效果的影响;研究了调驱剂用量与注入参数的优化设计方法;研究了现场施工工艺,包括调驱剂的配制工艺、注入方式等,并进行了现场施工。

This paper studied a new kind of decision-making technology(DAM)was studied.The distribution rule of the permeability and the water flood were studied using the DAM method.The well and the agent were decided by the DAM method.The different strength agents for profile control and displacement were researched including a kind of agent that could be used to displace the oil and profile control in deep reservoir.The injection order and the amount to be used of the different strength agent were studied.The influence of the order and volume would influence the effect of the work.
