摘要
根据基准面升降类型,将基准面旋回分别划分为向上变深的非对称型旋回层序(A型)、向上变浅的非对称型旋回层序(B型)、向上变深复变浅的对称型旋回层序(C型),根据可容纳空间的大小,又可以将其进一步细分为A1、A2、A3、B1、B2、B3,C1,C2,C39种类型,每种类型都与岩性油气藏存在一定的关系。通过建立等时地层格架,在等时格架下对每种层序类型的平面分布进行分析,从而预测岩性油气藏的有利分布区域,对油气勘探工作提供一定指导。
The datum cycle was divided into three types,which were the dissymmetry cycle type A of water depth became upwards,the B indicates the water became shallower upwards and the symmetry cycle type C indicates the water deeper and then shallower,according to the data.We can divided it further into nine types such as A1,A2,A3,B1,B2,B3,C1,C2,C3,according to the size of accommodation space,every type have relation to lithologic hydrocarbon reservoir.Though the building of equitime stratum framework,we can analyze the plane distribution of every cycle type,and then forecast the favorable distributed region of lithologic hydrocarbon reservoir,and provide the direction to the future oil/gas exploration activity.
