摘要: 东濮凹陷具有形成深层气的优越基础地质条件:两套优质烃源岩、多种类型的储集砂体和高异常孔隙发育、厚的岩盐和泥岩作为良好盖层。东濮凹陷深层气可分为煤成气、油型气和混合气3种类型,不同类型的深层气具有不同的空间分布规律。通过生烃史、充注史、构造演化史与油气运聚史综合分析,采用油气成藏的动态预测方法,总结出东濮凹陷深层气藏运聚成藏模式。

关键词: 东濮凹陷, 深层气, 成藏模式

Abstract: Dongpu sag is of the superior geological conditions for forming deep gas pools, including two sets of premium source rocks, variety of sand bodies, well developed porosity and thick halite and mudstone as cap rocks. The deep gas of Dongpu sag can be divided into three types such as coal-formed gas, petroliferous gas and combination gas, which have different space distribution for each type. This paper presents the model for deep gas migration and accumulation in Dongpu sag by analyzing the histories of hydrocarbon generation, filling and injection, tectonic evolution and hydrocarbon migration and accumulation, using dynamic prediction method for oil-gas accumulation.

Key words: Dongpu sag, deep gas, hydrocarbon accumulation model
