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。 In order to expand exploration in the western Liaohe depression, channel sand reservoirs are listed as the key exploration work. Based on the three-dimensional prestack seismic migration data in the southern part of western Liaohe depression, based on the study of sequence stratigraphic framework, the distribution of sand bodies in the Paleogene fluvial sands in the southern part of the western sag is studied by fine seismic data interpretation and attribute analysis Research and summarize the rules of sediment source migration, provide a reliable basis for sedimentary facies research and target optimization.
