岩性-地层油气藏勘探方法技术研究现状及进展

Current status and progress of exploration technology for lithologic-stratigraphic reservoirs in China

中国陆相含油气盆地岩性-地层圈闭(油气藏)具有圈闭边界条件复杂、形态不规则、赋存状态隐蔽、成藏条件复杂、油气运聚机理多样等地质特征。当前,中国形成了层序地层分析方法、"三相"联合解释技术等岩性油气藏勘探的基础研究方法以及叠前地震反演技术、地震属性分析技术、流体势分析技术、含油气检测技术等地震信息多参数综合评价方法。今后宜加强岩性油气藏勘探的基础地质研究,不断完善岩性油气藏勘探的标准和规范,重视地质和物探研究的有机结合,建立多学科、多专业的项目组,适时组织岩性油气藏勘探关键技术攻关,抓好岩性油气藏勘探的技术储备工作。

Lithologic-stratigraphic traps （reservoirs） in China are characterized by complex boundary condition, irregular shapes, subtle occurrence, complicated reservoir forming condition and various migration and accumulation mechanisms. At present, China has formed basic research methods including sequence stratigraphic analysis method and ＂three-phase＂ interpretation technology for lithologic reservoirs exploration, and multi-parameter comprehensive evaluation methods for seismic data, such as pre-stack seismic inversion technology, seismic attribute analytic technique, fluid potential analytic technique and oil and gas detection technology. It is proposed that we should strengthen fundamental geologic research and continuously improve the standard and criterion, attach importance to the organic integration of geological and geophysical exploration studies, timely organize key technology research and carry out technical storage for lithologic reservoirs exploration.
