摘　　要：牛东火山岩油藏在开发过程中表现出油井产能差异大、产量递减快的特点。通过开展油藏构造精细解释、储层分布特征、精细小层对比和储层反演研究以及应用注水试验井组微地震水驱前缘监测等技术,综合分析认为影响油田开发效果的主要因素有储层发育程度、储集空间类型及裂缝发育产状、地层能量以及注采井网方式等。这些认识对牛东油田减缓产量递减、提高动用储量和规模推广注水开发具有一定指导作用,也为同类油藏的开发与开采提供了借鉴。The volcanic reservoir in Niudong is characterized by great deliverability difference of oil wells and rapid production decline during the development.Based on the study of fine interpretation of reservoir structure,distribution characteristics of reservoir,fine comparison of sublayers and reservoir inversion and the application of microseismic monitoring technique of waterflood front in water injection testing well groups,it is considered that the main factors affecting the oilfield development effects are development degree of reservoir,type of reservoir porosity and development occurrence of fracture,formation energy and way of flood pattern.The research results may provide some suggestions for decreasing production decline,increasing producing reserves and wide application of water injection development and references for development and recovery of homogeneous reservoirs.
