| 摘 要： | 针对中国叠合盆地油气流动特征以及成藏规律,提出了复合含油气系统的概念。基于叠合盆地演化特征和油气地质特点分析,将复合含油气系统分为继承型、延变型与改造型三种基本类型。由于各含油气系统共享要素的不同,构成了“共盖复合”、“贯通复合”、“叠置复合”与“交叉复合”等多种复合方式;复合含油气系统的边界即是多个油气系统复合后的最大外边界。对复合含油气系统研究与评价,倡导以过程重建为主导的“顺藤摸瓜”的研究思路,并相应提出了“六定”的评价流程,对叠合盆地油气资源潜力评价与分布预测具有重要作用。

| Abstract: | In light of the characteristics of oil-gas flow in Chinese superimposed basins and the rules of reservoir formation, we put forward here a new concept of composite petroleum systems. Based on the characteristics of composite basin evolution and an analysis of the special features of oil-gas geology, we classify composite petroleum systems into three basic types: the successive, the ever modified, and the transformed. Because various petroleum systems may share different geological elements with one another, a variety of complexes may be formed, such as “the common sealing complex”, “the fault-connection complex”, “the stacking complex”, and “the intersecting complex”. The boundary of a composite petroleum system is determined by the outermost border of the composite system. In this paper, we present the corresponding research philosophy and evaluation methods for composite petroleum systems. We introduce a “six steps” research procedure, which is of great significance in effectively predicting the distribution and potentiality of petroleum resources in Chinese superimposed basins. |
