摘要
恩平凹陷经历了长达27年的勘探一直未获得突破,其主要原因是由于原二维地震资料品质欠佳,使得对凹陷结构、性质及成藏规律认识不清。2008年以来在恩平凹陷有针对性地采集了三维地震资料,在此基础上加强了区域研究与区带研究,进而开展了含油气系统及成藏条件综合分析,对该区的成藏规律有了新认识并提出了一系列勘探目标,首钻EP24-2-1井获得了商业性突破,这也是珠江口盆地油气勘探区域的突破,具有重要意义。
There had no breakthrough in a long exploration history up to 27 years in Enping sag,Pearl River Mouth basin,mainly due to poor quality of the 2D seismic data which had led to unclear knowledge in configuration,feature and hydrocarbon accumulation pattern of the sag.Since 2008,3D seismic data has been directively acquired,by which the regional and play researches have been emphasized.In addition,the petroleum systems and hydrocarbon accumulation conditions were comprehensively analyzed,resulting in new knowledge in hydrocarbon accumulation pattern of the sag and providing a series of exploration targets.A commercial breakthrough was obtained at Well EP24-2-1 drilled first,which is also a breakthrough in exploration areas and meaningful to Pearl River Mouth basin.
