摘要(Abstract):
系统论述了以含油气储集层为核心划分盆地成藏组合,并以成藏组合为基本评价单元的资源评价方法。在综合分析盆地构造、沉积、地层演化特征,储集层岩性和岩相特征,区域盖层发育,油气富集程度等因素的基础上,在纵向上和平面上对盆地的成藏组合进行了划分。通过统计不同的成藏组合内已发现油气藏的数量及规模,确定资源评价的计算方法和计算参数,最终获得符合目前盆地勘探现状及石油地质认识的资源量计算结果。以巴西坎波斯盆地为例,将该盆地划分出4个成藏组合,分别是:上部上白垩统-中新统Carapebus浊积砂岩储层成藏组合、中部下白垩统Macae碳酸盐岩储层成藏组合、下部下白垩统Lagoa Feia鲕粒灰岩储层成藏组合和底部下白垩统Cabiunas裂缝火山岩储层成藏组合,并分别计算了每一个成藏组合的预测待发现可采资源量,综合分析认为上部上白垩统-中新统Carapebus浊积砂岩储层成藏组合最为有利。
