摘要
江汉盆地沔阳凹陷新沟嘴组下段油气在纵向上主要分布于新沟嘴组下段层序的低位体系域 ;在平面上主要分布于三角洲前缘远端距离成熟烃源岩体最近的鼻状隆起带内 ;在成因上主要分布于侧向排烃为主、发育封闭型盖层的地区。杨林尾断阶带西南部周家湾断鼻群是勘探最有利地区。
This paper describes the hydrocarbon distribution laws principles of Lower Member of Xingouzui Formation in Mianyang depression,Jianghan basin,and on the basis of it indicates the favorable exploration area.The hydrocarbon of Xingouzui formation in Mianyang depression vertically distributes in low stand system of lower member sequence of Xingouzui formation,horizontally in the nose-shape uplifted belt which is in the distal area of delta-front near by the mature source rock,and genetically in area where hydrocarbon has been laterally expulsed and the cap rock is sealed.The most favorable exploration area is Zhoujiawan fault-nose groups set in southwest of Yanglinwei fault-terrace belt.
