东濮凹陷凝析气资源丰富,搞清其成藏主控因素与成藏模式对指导该区天然气勘探意义重大。通过解剖典型凝析气藏,综合分析凝析气成因类型、埋藏史与热演化史等资料,总结了该区凝析气成藏主控因素。综合考虑凝析气藏形成的地质背景、油气运聚输导体系及其组合特征,以及凝析气藏成因类型和油气分布规律,建立了“主控断层控浅不控深”和“气源断层深浅层双控”这两种不同类型的凝析气运聚成藏模式。结论认为,构造发育特征,尤其是主控断层与深层烃源岩的接触关系,直接决定了凝析气藏的形成及分布。 The condensate gas in Dongpu Depression is rich in resources. It is of great significance to guide the exploration of natural gas in this area because of its main controlling factors and reservoir forming patterns. By analyzing the typical condensate gas reservoirs and analyzing the types of condensate gas, burial history and thermal evolution history, the main controlling factors of condensate gas accumulation in this area are summarized. Considering the geological background of the formation of condensate gas reservoir, the migration and accumulation of oil and gas transport system and its combination characteristics, as well as the genetic type of condensate gas reservoir and the distribution of oil and gas, the “ ”Gas source depth and depth double control" These two different types of condensate transport accumulation mode. It is concluded that the tectonic development, especially the contact between the main fault and the deep source rocks, directly determines the formation and distribution of condensate gas reservoirs.
