Abstract:

The sedimentary facies,physical parameters of a reservoir as well as its fluid distribution characters and variation regularities could be described qualitatively and quantitatively in three dimensional space through compiling a software system in working station with the help of geological informations;the sedimentary facies model of the reservoir could be established based on the analysis of regional geology,and the data of drilling and grain size;reservoir parameter model could be built through calculating reservoir parameters such as the coefficient of diagenesis,porosity,permeability and heiterogeneity.Then the mathematical model of the reservoir could be built based on its special parameters and the phase states of oil or gas pools could be distinguished.These models could provide accurate parameters for reservoir numerical simulation and for hydrocarbon exploration planning.
