| 摘 要： | 众所周知,油气的生成、运移、聚集或逸散乃至破坏等各个环节,无一不与地下水的作用息息相关,因此研究含油气盆地的古水文地质演变是很有必要的。有鉴于此,本文试图对济阳拗陷的古水文地质条件(侧重于古水动力条件)及其与油气移聚的关系作一初步探讨。

| Abstract: | The paleohydrogeological condition and its relationship to the migration and accumulation of oil and gas in Jiyang Depression are studied with the cyclic standpoints. Depending on the hydrogeological cycles, the Cenozoic (K2) in this area can be divided into Eocene (E2), Oligocene (E3) and Nogene(N)-Quaternary(Q). Each cycle can be divided into two hydrogeological stages of sedimentation and seeping. The water-exchanges of Shahejie Formation (except Es4) are evaluated. The result shows the activity of deposition water is far exceeded than that of seeping water. This condition is quite favourable for migration, accumulation and preservation of oil/gas. The prospects of oil and gas in this area are evaluated in accordance to the paleohydrodynamic effects, and the time, trend and size of migration and accumulation of oil/gas are discussed as well. |
