| 摘 要： | 基于东营凹陷草113-郑气2地区现今实测地层流体压力和典型剖面压力分布特征,研究认为这个地区地层异常压力主要发育在Es3中、Es3下和Es4,纵向上可分为3个压力系统:正常压力、高压异常和异常高压。应用盆地数值模拟法恢复了草113-郑气2地区的压力演化史,结果表明超压主要经历了早期形成、下降调整和晚期发育3个阶段。分析证明超压主要由欠压实作用、烃类生成作用及蒙伊转化脱水作用造成,其演化阶段与油气成藏期具有很好的相关性,是油气运移的动力。 |

| Abstract: | According to the measured formation pressure and typical profile pressure distribution characteristics,we find that the overpressure occurs in the lower-middle third Member and the fourth Member of Shahejie Formation in Dongying Sag.In vertical it is divided to three pressure systems: normal pressure,high pressure abnormal and abnormal high pressure.We analyze the paleo-pressure evolution using the Basin Modeling.Research shows that the overpressure evolution mainly experiences three stages:original formation,meta-declining and latest-raising.Based on former analysis,overpressure is mainly caused by undercompaction,hydrocarbon generation and clay mineral transformation.The evolution of overpressure not only is well related with the hydrocarbon accumulation stages but also provides enough power. |
| Keywords: | Dongying Sag Cao 113-Zhengqi 2 area abnormal pressure simulation over pressure evolution accumulation power |
