摘要
垦东凸起四周临近生烃凹陷,油气资源丰富.上第三系披覆沉积在中生界之上,在披覆构造背景下,发育了构造、岩性、岩性-构造等多种类型圈闭.垦东凸起可划分为3个油气运聚系统,油藏类型以构造、岩性-构造油藏为主.主要含油层系为馆陶组上亚段.断层发育程度、构造部位、储集层岩性是控制油气分布的主要因素.运用测井约束反演技术,对上第三系储集层的空间展布进行了分析和描述.
Kendong uplift is surrounded by hydrocarbon-generating sags and has a great resource potential. The Neogene sequences are deposited on Mesozoic buried hills, resulting in multiple trap types such as structural, lithologic and litho-structural traps. Kendong uplift can be divided into three migration- accumulation systems, in which reservoirs types are dominated by structural and litho-structural oil reservoirs in drape structure, with Upper Guantao Formation being the main oil-bearing interval. Fault development, structure geometry and reservoir lithology are the major factors to controll oil and gas distribution. The spatial arrangement of these Neogene reservoirs can be analyzed and described by using a logging- constrained inversion technique.
