摘　　要：研究了复杂岩性和多套油水系统、断块油藏的合理开发问题。以实际油藏为例,通过各油井开发差异对比分析、不同油水系统动用差异分析,找出影响开发效果的因素。研究认为,对于复杂岩性多底水小断块油气藏,制定合理的油井工作制度,采用适当的采油速度,依靠底水天然能量,采取一套井网同样可以取得较好的开发效果。同时,老井侧钻既能挖掘井间及高部位剩余油,完善井网,又能有效控制底水锥进,是复杂底水小断块油藏经济高效开发的措施方法。该研究对于多油水系统、多岩性油藏合理开发方案制订及提高其开发效果具有重要意义。This paper studies how to develop fault block oil reservoirs with complex lithology and several of oil-water systems.With a practical reservoir as an example,this paper correlates the recovery difference of oil wells,analyzes the producing difference of different oil-water systems,and finds out the factors affecting development result.The study shows that good development result can be achieved with just one pattern in such reservoirs by producing with proper choke,at rational rate of oil production,and utilizing natural energy of bottom water.In addition,side-tracking in old wells can produce residual oil between wells and on structural high,improve pattern arrangement,and control bottom water coning;it is an effective method for developing minor fault block reservoir with complex lithology and bottom water.This study is very important for formulating rational development scheme and improving development response in similar reservoirs.
