摘要
叠合型盆地的复合含油气系统导致了其断层封闭性评价的特殊性。在前人成果的基础上,总结了断层的封闭机理、影响叠合型盆地断层封闭性的主要因素(断层的产状、断层的力学性质和应力状态、断裂带内充填物的性质、断层的地质背景及其活动性),建立了叠合型盆地的断层封闭性评价的地质模型,并讨论了运用该模型建立相应的数学模型实现定性、定量评价等问题。该模型采纳了复合含油气系统的思想,重视断层封闭性的发展史及其与生排烃关键时刻的匹配,对我国叠合型盆地的断层封闭性评价具有一定的借鉴意义。
A superimposed basin tends to containing complex petroleum system, which leads to particular evaluation of its fault sealing. Based on previously studied results, the mechanism of fault sealing and such controlling factors as occurrence, mechanical nature and stress condition of fault, as well as filled material nature, geologic setting and activity in fault are reviewed, and a geologic model for evaluation of it is developed. Also, how to set up a mathematical model to carry out qualitative-quantitative evaluation using this model is discussed. With the complex petroleum system concept, fault-sealing history and key-time matching for generation and expulsion of hydrocarbons, this model could be served to in-depth evaluation of fault sealing in superimposed basins in China.
