摘要
利用塔里木盆地麦盖提斜坡西段二维与三维地震资料,对奥陶系古潜山顶面进行了精细标定、解释、属性分析及古地貌恢复。分析研究结果表明,该区奥陶系古潜山古水系较为发育,下奥陶统古潜山暴露地表的时间较长(近45Ma),喀斯特斜坡带风化壳储层发育,且受古构造和古水系发育控制。
By using 2-3D seismic data of the West Maigaiti Slope to interpret Ordovician paleo-buried hill top surface and rebuild paleo geomorpholog and analyze seismic attribute,it can be inferred that the paleo-drainage system of Ordovician paleo-buried hill is more developed.For Lower Ordovician paleo-buried hill being exposed to the surface for long periods（about 45 Ma）,weathering crust karst reservoir developed in karst slope regions.And the development of weathering crust karst reservoirit is controled by paleostructure and palaeo-channel development.
