摘　　要：根据荆沙组的基本地质特征,综合分析了成藏条件。认为长期继承性发育的构造、紧邻生油洼陷和晚期构造活动是荆沙组油气藏形成的先决条件。油气成藏的关键因素是:圈闭、断层和砂体的配合。建立了油气成藏模式,指出该区可发育垂向和侧向两种油藏模式。认为盐隆构造、深大断裂构造是寻找垂向油藏的有利区带。The hydrocarbon accumulation is explored in the light of the geology of the Jingsha Formation.The prerequisites for the hydrocarbon accumulation include long-term inherited structures,close association with oil-generating depression and later structural destruction in the Jingsha Formation.The key factor includes the matching of favourable traps,faults and reservoir sandstones.The models for the hydrocarbon accumulation are presented in this study,including vertical and lateral hydrocarbon accumulation.The salt-dome structures and deep-seated fault structures may be considered as the favourable areas for the vertical hydrocarbon accumulation.
