Abstract:

According to the discussion on numerical model of sedimentary basin,including the conception,the composition and the problenms remained in actual application of the modeling,it is proposed that,for different research objects of different structural grades of the basin,basin modeling must be different.This paper describes a numerical basin model within sedimentary cover of the basin,dealing with the composition of geological model,the derivation of mathematical model and the numerical solution.The main parts of the models include compressive diagenesis,geothermal field,geopressure field and geometrical variation of the basin.The paper also discusses the selection of key parameters,calculaton method and verifying of the models.
