摘要

苏北盆地高邮凹陷为新生代箕状断陷,油气藏以常压为主,具有多期演化的特点,存在古近纪三垛期早期成藏和新近纪盐城期晚期成藏2个阶段,发育网状、层状和断裂带3种类型的输导体系,具有侧向、垂向、网状3种油气运聚模式。斜坡带K2t—E1f油气以侧向运聚为主;深凹带E2d—E2s油气为网状运聚;断裂带油气主要为垂向运聚,包括浅(Ny)、中(K2t—E1f)、深(Pz)3 套含油气层系。
The Gaoyou Depression in the North Jiangsu Basin is a Cenozoic halfgraben-typed fault depression. Its hydrocarbon pools are dominated by normal pressure, which have the characters of multi-stage evolution and the two stages of pool formation early in the Sanduo period of the Paleogene and late in the Yancheng period of the Neogene and develop reticulated, bedded and faulted three types of conduit systems and lateral, vertical and branchy three kinds of hydrocarbon migration and accumulation patterns. The hydrocarbon migration and accumulation is mainly lateral in the K_2t-E_1f Formation of slope zones, branchy in the E_2d-E_2s Formation of deep depressed zones and vertical in faulted zones which including shallow (Ny), medium (K_2t-E_1f) and deep three sets of petroleum measures.
