黑池梁地区长兴组—飞仙关组沉积相及储层预测

黑池梁地区是川东北通南巴构造带中隆升幅度最高的部位,长兴组—飞仙关组沉积时处于广旺—开江梁平陆棚东侧,具有发育礁滩相储层的沉积背景。通过地表露头、岩心观察和钻井资料分析,认为黑池梁地区长兴组—飞仙关组可划分为陆棚相、台地前缘斜坡相、台地边缘生物礁滩相、开阔台地相、局限台地和台地蒸发岩6个相带。依托三维地震资料,结合已知礁滩相气藏的勘探成果、地震反射特征和地震属性分析,建立了该地区长兴组—飞仙关组沉积及储层发育模式,预测M2井以东地区与H1井井区为礁滩相储层有利勘探目标区。

Sedimentary Facies and Reservoir Prediction of Changxing Formation -Feixianguan Formation, Heichiliang Area

Heichiliang area is one location with the largest uplift in Tongnanba structure belt, northeastern Sichuan Basin. Changxing and Feixianguan formations in this area are deposited at east margin of Guangwang-Kaijiang-Liangping continental shelf and a sedimentary pattern of both bioreef- and shoal-facies reservoirs are developed here. In this study, it is considered after an analysis on the outcrop, core observation and drilling data that, Changxing-Feixianguan formations in Heichiliang area can be classified ...
