摘　　要：目前研究区延7油藏主要靠天然能量开采,油区已处于中低等含水阶段,油藏能量下降较快,部分井产量较低,迫切需要将油藏地质与开发动态分析有机结合。通过精细油藏地质研究,在目前井网地层能量及开发动态等油藏工程分析基础上,优选注采井网形式,进行注水开发方案设计和部署研究。通过对延7油层组油藏地质、油藏等特征及注水参数的深入研究,为以后延7油藏注水开发提供可借鉴资料。At present,Yan7 oil reservoir in the study area is mainly exploited by natural energy,and the oil area is in the middle and low water cut stage.The energy of the oil reservoir is declining rapidly,and the production of some wells is low.It is urgent to combine the oil reservoir geology with the development performance analysis.Through detailed reservoir geological research,based on the reservoir engineering analysis of the current well pattern,formation energy and development performance,the injection-production well pattern is optimized,and the water injection development scheme design and deployment research are carried out.This time,through in-depth study of reservoir geology,reservoir and other characteristics and water injection parameters of Yan7 oil reservoir group,it provides reference data for future water injection development of Yan7 oil reservoir.
