Geologic Model for Fault Sealing Evaluation of Superimposed Basins

Abstract

Abstract: A superimposed basin tends to containing complex petroleum system, which leads to pa1ticular 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 petmleum system concept, fault sealing history and key time matching for generation and expulsion of hydro-carbons, this model could be served to in-deplh evaluation of fault sealing in supe1imposed basins in China.

Key words: superimposed basin, fault, sealing, geologic model, history
