东濮凹陷白庙陡岸断阶带砂体分布模式
|
摘要
为了探索白庙陡岸断阶带砂体展布规律 ,充分利用钻井、录井、测井资料以及先进的地震反演技术 ,分析认为该区砂岩主要发育于断阶带主体前缘、前缘断层下降盘深洼陷区、构造北翼和构造南翼。阐述砂岩受断层、古构造、古地形、沉积微相控制 ,平面非均质性强 ,形成岩性 -构造油气藏。建立了该区砂体分布模式 ,有利于指导陡岸带勘探
In order to explore the expanding feature of sandstone body in the split belt in Baimiao area,making fully use of the drilling data,logging data,and the advanced technology of seismic inversion,have made sure that the sandstone mainly developed in the front of the split belt,the deep depression area of the downthrow of the front faults,the northern flank and the southern flank of the structure.The sandstone body distribution is controlled by the faults,the palaeostructure,the palaeotopography and the sedimentary microfacies.The lateral heterogeneity is strong.The lithological structure reservoir was formed.The sandstone distribution model is built as so to be in favor of guiding the exploration in barranca split belt.
