Abstract:

Pinghu oil gas field in East China Sea is a massive,bottom water drive light crude oil pool.The reservoir heterogeneity is relatively serious,and the distribution of muddy interlayers is a big variety.It is difficult to describe the size of muddy interlayers by traditional geologic model building method.It takes about 15 days and more than 10 times modifying the parameters of history fitting and reservoir simulation on H2 resevoir,because the geological model by traditional method can not describe clearly the reservoir heterogeneity,and the result of history fitting is not good.Use stochastic simulation to built prediction model,then,3-D reservoir attribute model is revised by the prediction model.It only takes 3~4 days and 5~6 times modifying the parameters of the history fitting and reservoir simulation.The result is very good and exact.

Key words: interlayer, interlayer model, stochastic simulation, application
