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.
