运用成藏动力学系统的理论和方法,对垦西地区的成藏模式进行了研究分析,指出该区存在侧向和垂向2 大类型的油气运聚成藏模式,前者主要包括沙四段烃源岩油气的侧向运聚成藏模式、沙三段烃源岩油气的侧向运聚成藏模式和沙四段烃源岩凝析油气的侧向运聚成藏模式3 种类型,后者包括沙四段烃源岩油气的垂向运聚成藏模式和沙三段烃源岩油气的垂向运聚成藏模式2 种类型。

By theory and method of mineralization dynamics system, this paper has studied the mineralization pattern in Kenxi area , indicating that there are two oil and gas migration patterns —the lateral and the vertical. The former mainly consists of 3 types of pattern ,that is ,lateral migration of hydrocarbon source rock reservoir in the fourth section of Shahejie Formation , and that of in the third section , and lateral type of hydrocarbon source rock condensate reservoir in the fourth section. While the latter includes 2 types of vertical patterns of hydrocarbon source rock reservoir in the third and that of in the fourth section of Shahejie Formation.
