摘　　要：神泉油田侏罗系油藏属于典型薄互层状低阻油藏,已进入中高含水开发阶段,亟待探明剩余油分布状况并进行挖潜方案调整。采用常规水淹层测井解释方法和动态分析法,分析神泉油田三间房组的水淹规律,研究储层水淹规律的影响因素。研究表明,储层物性特征是影响储层水淹程度的主要因素,构造、断层和注采系统是影响水淹规律的次要因素。The Jurassic reservoir of Shenquan oilfield is a typical thin- interbedded and low resistance reservoir,and it currently entered middle- high water cut period,so it is urgent to find the remaining oil and tap the reservoir potential. This paper comprehensively utilizes the combination method of the conventional well logging interpretation of water flooded layer and the dynamic analysis to get the water- flooded rule of Sanjianfang formation in Shenquan oilfield; at the same time,the influencing factors of the water- flooded reservoir are analyzed. Its results show that characteristics of reservoir physical property is the main factor to control the degree of water- flooded reservoir;structure,fault and injection- production system are the secondary factors of the water- flooded rule.
