陆相盆地隐蔽油气藏综合勘探方法与应用初探
吴东胜 扬申谷 刘少华
摘 要:隐蔽油气藏综合勘探方法是层序地层学框架下的多学科综合研究,应以信息集成系统为平台,分为基础资料整理、区域综合评价和目标预测3个阶段进行.基础资料整理应建立信息平台,以实现多源数据和成果的集成化管理;区域综合评价可分为区域性等时层序地层格架建立、沉积体系和隐蔽圈闭特征研究、隐蔽油气藏成藏规律研究、隐蔽油气藏空间分布预测和评价等步骤进行,以阐明隐蔽油气藏的类型、特征、形成条件和空间分布;目标预测分工区选择、高精度层序格架对比、隐蔽圈闭识别和描述、隐蔽圈闭含油气性评价等步骤进行,以识别和评价隐蔽油气藏并最终提供钻探目标.信息集成系统可基于组件式地理信息系统(COM GIS)开发,并具备油气勘探成果信息和多学科数据的集成化管理、研究成果的综合表达与应用及海量数据的挖掘等功能.苏北盆地金湖凹陷戴南组的隐蔽油气藏研究表明了综合勘探方法的实用性和有效性.
