摘要
蠡县斜坡是位于饶阳凹陷西部的一个构造一沉积斜坡。该斜坡油气富集,油气藏类型多样,油气成藏机理复杂,受构造、岩性、沉积微相等多因素控制。本文依托叠后三维地震数据体和钻井等资料,将GeoEast解释系统提供的构造导向滤波、地层体切片、谱分解、油气检测等模块技术应用于蠡县斜坡的岩性油藏评价与建产,取得了较好的应用效果,有效降低了钻探风险。在古近系沙二段识别出两期5个滩坝砂体,预测有利区带面积43.3km^2,石油地质储量近两千万吨。
Lixian Slope is a sedimentary slope structure located in the west of Raoyang Sag. This slope has various reservoir types with vast hydrocarbon reserves and complex accumulation mechanism controlled by many factors, such as structure, lithology, and sedimentary microfacies. Based on poststack 3 D seismic and drilling data, we conduct lithologic reservoir evaluation and construction of Lixian Slope with tools provided by GeoEast including structure-guided filtering, stratigraphic slice,spectrum decomposition, hydrocarbon detection,and so on. According to the evolution, 5 beach-bar sand bodies in Es2 are identified, and a 43.3 km^2 favorable area with 20 million tons of oil reserves is delineated.
