Abstract: Fossil crust of weathering played an important role in the reservior, migration and accumulation ofoil and gas, for example the formation of Some important oil or gas pools in the North of China, OrdosBasin and Tarium Basin, which is related to the fossil crust of weathering on the top of carbonate forma-tions.The synthetically fluid dynamics, chemical dynamics and chemical thermodynamics were used tomodel dynamically the rock- fluid reaction process of and to restore the fluid dynamic field and chemicaldynamic field of the fossil crust of weathering during the period of weathering and leaching, so as to pre-dict the changes of physical parameters, such as porosity and permeability, and to provide the parametersfor reservior quantative evaluation.The modelling reseach on the rock- fliud dynamics is to restore dy-namically the interaction process between the rock and fluid, which has important theoretical and practi-cal meanings.
