摘要
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 Dongpu sag is prolific in condensate gas. A correct understanding of the main controlling factors and establishment of condensate gas pooling models are of great significance to gas exploration in the study area. The main controlling factors of condensate gas pooling are summarized through dissection of the typical condensate gas reservoirs and integrated analyses of the genetic types, burial history and thermal evolution of condensate gas. Two different models of migration and accumulation of condensate gas are established based on comprehensive research of the geologic settings, carrier systems and their combinations, as well as the genetic types and distribution of condensate gas reservoirs. The features of structure development and, in particular, the connection of the major faults with the deep source rocks directly determine the formation and distribution of hydrocarbon reservoirs.
