不整合是斜坡区重要的输导体系及油气藏类型,准确定量地确定不整合面的深度具有重要的地质意义。但由于地震资料分辨率较低,岩心及倾角、成像测井资料有限等原因,常规测井资料定量识别成为目前主要的不整合面深度确定的主要手段。应用最优二分割方法,借助DPS软件系统对文安斜坡馆陶组底不整合面进行了确定,可为下一步斜坡外带的不整合运聚成藏研究奠定重要基础。
Unconformity is an important transport system and reservoir type in the slope area. It is of important geological significance to determine the depth of unconformity accurately and quantitatively. However, due to the low resolution of seismic data, core and dip, limited logging data and other reasons, the quantitative identification of conventional logging data has become the main method of determining the depth of unconformity. The optimal two-part method was used to determine the unconformity of the Guantan formation at Wenan slope by means of DPS software system, which laid an important foundation for the unconformity migration-accumulation accumulation in the next slope out-ramp.
