Overview of study on carbonate reservoir simulation

The reserves of the carbonate reservoirs in the world are half of the whole proved- up reserves,and vital to the world 's oil and gas production.This paper introduces the related carbonate reservoir simulation models,and the critical factor to the model,which named inter-porosity flow function,is presented in details.Also,the methods of carbonate reser- voir simulation are introduced,which are how to establish the pseudo-capillary pressure curve and the relative perme- ability curve,simulation method using a single matrix block model to investigate the driving mechanism of production, and the streamline reservoir simulation.Finally,the function and models to simulate carbonate reservoirs in the eommer eial simulators are presented.So before to simulate the car- bonate reservoir,based on the deep knowledge of geology and production of the reservoir,the engineers choose the ap- propriate simulation model and simulation methods to simu- late and predict the reservoir production.
