【摘要】 渤海A油田的储层非均质性较强,厚度和物性在横向上存在着较大变化,同时潜力砂体的含油气性不确定,这些因素给油田开发方案的设计和实施带来了较大风险。通过层位综合标定、地震属性分析、叠前ISIS反演和岩性体分类等地球物理技术的结合应用,不仅对储层的响应特征、展布范围和物性变化有了更深入的认识,对储层的含油气性也有了较准确的预测,进而指导了砂体的追踪描述、井位的优化部署和储量的升级评价等工作,保障了油田的顺利开发。更多还原

【Abstract】 Strong heterogeneity is in the Bohai A oilfield reservoir and great change of thickness and physical property exist horizontally,and potential of sandbodies oiliness is not clear.These factors of uncertainty brings bigger risk to the oilfield development design and implementation.Through such combined geophysical technology as composite calibration of horizon,seismic attributes analysis,prestack inversion ISIS and lithologic body assortment,the response feature analysis,distribution scope and physical property of the reservoir has been better recognized,potential of oiliness has been predicted more accurately,which make further guidance to sand body track description,well location optimized fitting,capacity upgrade evaluation and guarantee the smooth oilfield development.更多还原
