摘要: 陆相致密油是中国近期现实的非常规石油资源,是国内石油资源储产量增长的重要补充。研究团队立足国家科技重大专项“致密油富集规律与勘探开发关键技术”研究目标引导、国家重点实验室室内测试和中石油8家油公司现场试验,针对中国陆相致密油理论技术研发和勘探开发实践取得3方面研究进展。①形成条件方面:发现纹层状富有机质页岩是主力烃源岩,发育陆源碎屑、内碎屑等多种类型有利储集层,主要包括源内和近源2种大面积连续分布的成藏组合;②富集规律方面:明确有利储集相带、近烃源中心、一定构造背景是富集高产的3个共性主控因素,评价致密油资源规模为106.5×108t,识别出40个富集区带,储备了一批可钻“甜点区”;③勘探开发关键技术方面:多尺度致密储层表征、资源分级评价、“甜点区”地震响应及工程评价、致密储层改造技术、致密油有效开发技术等取得新进展。研究成果支撑中国陆相致密油整体快速发展,截至2018年底,已探明石油地质储量为4.37×108t、三级储量为30.19×108t,新建产能为331×104t。建议后续研究聚焦碎屑岩、混积岩—沉凝灰岩、湖相碳酸盐岩等3大领域,着力深化富集规律研究、甜点评价预测、开发关键技术、储层高效改造技术、重点盆地实践应用等5方面研究,支撑中国陆相致密油地质工程一体化稳步发展。
