Abstract: The article briefly deals with some of the basic characteristics of carbonate reservoirs in middle Hebei and their principal mechanism in water flood recovery. Laboratory results are analyzed for waterfloods in the fracture systems and compact matrices. In the last part, the results of pilot flood carried out in the Longhuzhuang oil field are used to explain the mechanism of intermittent injection which is proposed to be introduced for increasing the rate of recovery of carbonate reservoirs in Middle Hebei.

摘要： 本文简述冀中碳酸盐岩储层的基本特性及其注水采油的主要机理,进而分析根据这种油藏特性所进行的一系列室内注水采油实验的结果,包括裂缝系统和致密岩块的注水采油特性。最后,结合龙虎庄油田矿场间歇采油实验结果的分析,阐述间歇注水采油的机理,提出在冀中碳酸盐岩油藏开展间歇注水采油提高采收率的矿场实验的建议。
