【Abstract】 In order to discuss the adaptability, advantage and disadvantage of various stochastic simulation for sedimentary micro faces of reservoir are analyzed, and truncated gaussian simulation and sequential indicator simulation, which are generally used in quantitative description of reservoir, will be adopted to simulate the framework of faces of a low permeable reservoir for the comparative study of different simulation technologies. The results of stochastic simulation indicate:(1)the reliability of simulating result is quite different by different simulation methods;(2)sequential indicator simulation is a much more preferable way for the simulation of complicated heterogeneous reservoirs than truncated gaussian simulation, (3)the result of the former is more reliable matching with the true cases, while the latter shows a lower accuracy.更多还原
