【摘要】 为拓展辽河西部凹陷勘探领域,河道砂体储层被列为勘探工作重点。利用辽河西部凹陷南部地区三维连片叠前时间偏移地震资料,在层序地层格架研究基础上,应用精细地震资料解释及属性分析等技术,对西部凹陷南部古近系河道砂体分布进行研究,总结沉积物源迁移规律,为沉积相研究及目标优选提供可靠依据。更多还原

【Abstract】 In order to expand the exploration area in the Western Depression of Liaohe Oilfield, channel sand reservoirs have been highlighted in exploration work. The distribution of Palaeogene channel sand in the south of the depression has been studied by using techniques of fine seismic data interpretation and attribute analysis based on sequence stratigraphy study by joint processing of 3D pre-stack time migration data. The rule of sedimentary source migration has been generalized. This study provides reliable basis for sedimentary facies study and target optimization.更多还原
