辽河油田西斜坡断块油藏在牵引流扇三角洲、重力流近岸水下扇沉积等不同沉积类型发育的复杂开发地质条件情况下,面临着储层砂体分布不清、砂体连通性不落实及隔夹层分布特征不清等难点和问题。传统的地质研究不能满足开发需求。本次研究针对性的引进拆分道精细标定、年代地层相及波形分析等三维地震技术进行研究及应用,取得较好的效果,有效指导西斜坡稠油开发地质储层研究及井位优化部署工作。
In the complex development geological conditions with different sedimentary types, such as the traction fan delta and the gravity flow nearshore subaqueous fan, the western slope block reservoir in Liaohe Oilfield is confronted with the unclear distribution of reservoir sand body and the connectivity of sand body Implementation and the inter-mezzanine distribution is not clear and other difficult issues and problems. Traditional geological research can not meet the development needs. In this study, we introduced the application of three-dimensional seismic technology such as fine resolution of split path, age stratigraphy and waveform analysis, and achieved good results, which effectively guided the development of geological reservoirs and well location optimization of heavy oil in the western slope jobs.
