本文以车镇北带砂砾岩扇体油藏为研究对象,通过大量地震、钻井资料的综合分析,在下第三系沙四段-沙一段地层中划分出九个三级层序,建立了车镇地区沙河街组层序地层格架。综合运用了高分辨率地震处理解释方法,采用古地貌分析、地震属性预测和反演等一系列地震描述技术,建立了一套针对砂砾岩扇体油藏油气藏描述方法,预测了扇体的有利发育区。 Based on the comprehensive analysis of a large number of earthquakes and drilling data, nine third-order sequences are divided into the third member of Shahejie Formation, Sequence stratigraphic framework of Shahejie Formation in the town area. Comprehensively applying high-resolution seismic processing and interpretation methods, a series of seismic description techniques for paleo-geomorphologic analysis, seismic attribute prediction and inversion and a series of description methods for sandstone-conglomerate fan reservoir reservoirs have been established. Favorable development zone.
