3D Geological Modelling of the Series of Deep Strata in Xiaermen Oilfield

The technology of 3D computer modeling has been widely used in reservoir fine description, especially in the development phase. Itpsilas an effective way to enhanced oil recovery and reduce water cut. This paper presents an example of the application 3D modeling to the series of deep strata in Xiaermen Oilfield, Henan, China. In this paper, the geological, geophysical, petrophysical and engineering informations are integrated then a comprehensive reservoir model is built that can enhance reservoir management planning. First, a 3D structural model is built which consists of the faults model and the horizon model, then based on the structural model a 3D stochastic microfacies model of each reservoir zone through the analysis and integration of core and log data from 15 wells in the study area. Second, the physical property data is analysed among the microfacies and builds the petrophysical model which interpolation method is controlled by the distribution of the microfacies.
