摘　　要：为了进一步扩展和深化高北斜坡带中深层岩性油气藏的勘探领域,针对该区岩性圈闭识别评价与有效储集砂体预测所面临的地质问题和技术问题,以富油气凹陷岩性油气藏勘探理论为指导,充分利用GeoEast解释系统中的地震多属性分析、储层特征参数分析、储层物性参数评价等多项技术,针对性地提出了岩性圈闭识别评价与有效储集砂体预测的技术思路和配套技术。通过高北斜坡带中深层岩性圈闭识别评价与勘探实践认为,该区岩性圈闭识别评价与有效储集砂体预测的研究思路和技术方法是可行的,为岩性圈闭的识别和勘探指明了方向和目标,且实施钻探后也取得了良好的地质效果和经济效益。Middle and deep lithologic reservoirs in Gaobei Slope are complicated and difficult to be identified in the hydrocarbon exploration. Based on the oilrich sag lithologic reservoir exploration theory, we conduct lithologic trap identification and evaluation with tools provided by GeoEast interpretation subsystem, such as multi-attribute analysis, reservoir feature parameters analysis, and reservoir physic parameters analysis. At the same time we put forward a strategy and a set of techniques for lithologic trap identification and evaluation, and sandstone prediction. The practice in Gaobei Slope shows that our mentioned ideas achieve great success proven by drilled wells.
