| 摘 要： | 江汉盆地江陵凹陷主力烃源岩为新沟嘴组下段,梅槐桥—资福寺向斜是生油中心。已经发现的油气藏具有圈闭规模小、充满度低、环生油中心较集中分布的特点和规律,以断层为主的输导体系和储层物性是油气成藏和富集的主要控制因素。江陵凹陷白垩—第三系资源探明率仅为12.4%,探明程度很低,还具有很大的勘探潜力。荆州背斜带南缘斜坡和梅槐桥洼陷内构造—岩性及岩性圈闭、万城断裂上盘白垩系及前白垩系古潜山、公安单斜带火山岩储层及生油洼陷中的页岩油是今后一段时间油气勘探的突破方向和领域。

| Abstract: | In the Jiangling Sag of the Jianghan Basin, the lower Xingouzui Formation served as the main source rocks, and petroleum generated mainly in the Meihuaiqiao-Zifusi syncline. The discovered oil and gas pools are featured by small trap scale, low charging extent and located around oil sources. Transformation system mainly of faults and reservoir physical property controlled petroleum accumulation. From Cretaceous to Tertiary in the Jiangling Sag, the proved rate is 12.4%, indicating for low exploration extent and good potential. The southern slope of the Jingzhou anticline, the tectonic-lithologic and lithologic traps in the Meihuaiqiao sub-Sag, Cretaceous and Precretaceous buried hill in the Wancheng fault, the volcanic reservoirs in the Gongan monocline, and the shale oil in oil source sags are the targets for future exploration. |
