摘要: 对济阳坳陷1996~2002年期间失利的174口预探井的分析表明,对油气运移、圈闭封堵、储集性能、油气充满度、盖层以及源岩这6种地质条件的认识不足导致了钻探失利。根据含油层系、构造带和圈闭类型等不同石油地质条件,研究了各种导致探井失利的地质因素的分布特点,分析了济阳坳陷圈闭地质风险的成因及主控因素。结果表明,油气有效运移通道、二次运移动力和油气充满度应是当前基础理论研究的重点。

Abstract: Analysis on 174 unsuccessful preliminary prospected wells drilled from 1996 to 2002 shows that insufficient understanding of geologic conditions such as oil-gas migration,seal of trap,reservoir property,oil-gas filling degree,cap rock and source rock may lead to unsuccessful drilling.The geological factors that cause unsuccessful drilling in different oil-bearing formations,different structural belts and different trap types are classified.The origin and control factors for geologic risk of oil-bearing trap in Jiyang Depression were defined.It is pointed out that the effective migration passage,secondary migration force and oil-gas filling degree are the most important basic theories to be studied at present.

Key words: Jiyang Depression, oil and gas exploration, preliminary prospected well, unsuccessful reason, geological factors, exploration theory
