摘　　要：含油气系统地质理论是油气勘探战略选区的基础,随非常规石油地质理论的发展,自身也亟需丰富发展,以更好地指导油气勘探。在综述含油气系统理论沿革和分析其发展趋势的基础上,对准噶尔盆地玛湖大油区的发现史进行了研究。结果表明,玛湖大油区的发现,是含油气系统理论发展的缩影。玛湖大油区具备源储耦合成藏的基本条件,发育了有序分布的全类型油气藏,为全油气系统理论的确立提供了实证。以玛湖凹陷为例,全油气系统的勘探可实现4个方面的拓展:由源外向源内拓展,由常规向非常规拓展,由浅层向深层拓展,由单一圈闭向连续地质体拓展。Petroleum system is a basic tool for strategic oil and gas exploration and the geological theory of petroleum system needs to be ex⁃tended with the development of unconventional petroleum geology theory.Based on the review of the evolution of petroleum system theory and the analysis of its development tendency,the paper studies the discovery history of the large oil province of Mahu.The research results show that the discovery of the Mahu large oil province represents a microcosm of the development of petroleum system theory.The large oil province of Mahu where all kinds of reservoirs can be found has the basic conditions of source⁃reservoir coupling,providing empirical evi⁃dences for the establishment of the total petroleum system theory.Taking Mahu sag as a case,there are possibly four directions for the ex⁃ploration of total petroleum system-from outer⁃source to inner⁃source,from conventional resources to unconventional resources,from shal⁃low strata to deep ones,and from single traps to continuous geological bodies.
