摘要
文中通过对结构构造及演化过程的分析，指出江陵凹陷荆州背斜带形成于荆沙中期，是盐隆作用、构造运动、火山活动等共同作用的结果。解析已经发现的油藏认为，荆州背斜带油气运移效应明显，在构造顶部以Ⅰ油组复杂断块油藏为主，具有断层控藏特征；南部斜坡带及洼陷带以Ⅱ油组岩性油藏为主，具有砂岩储层控藏特征。
Abstract
Based on the analysis of structural tectonics and evolution, Jingzhou anticlinal belt of Jiangling Sag, which uplifted during the middle period of Jingsha Formation sedimentary, was a result of general effect of salt swell action, tectonic movement and volcanic event. An evident migration effect is observed by dissecting the oil pool in Jingzhou anticlinal belt. The oil measuresⅠ at the top of structure are mainly complex fault block, mostly controlled by faults, while the lithologic reservoirs of oil measures Ⅱ are mainly in southern ramp region and low-lying belt by sandstone reserve, controlled by sandstone reservoir.
