摘要
沉积微相数据分布具有结构性和随机性,符合地质统计学的研究范畴。在长庆油田,基于ArcGIS地质统计学模块实现了沉积微相自动识别和沉积微相图的自动绘制,包括数据处理及沉积微相编码、工区网格化、指示克里格插值、沉积微相叠置、沉积微相边界追踪及沉积微相成图。结合地质工作者的认识加以修改,最终成图与手工编制的图吻合较好,基本反映了研究区沉积相带分布特点。
Sedimentary subface data,which is both structural and stochastic,is the subject of geostatistics.Using ArcGIS Engine to achieve automatic identification and mapping of sedimentary subfacies in Changqing oilfield includes data processing,sedimentary subfacies coding,facies gridding,Kriging interpolation,superposition,search of boundaries and drawing sedimentary microfacies map.The resulted map is basically consistent with that drawn by hands and reveals the distribution characteristics of the study area.
