Geological Modelling Of Chang-6Reservoir In Southern Baoziwan

Chang6reservoir of baoziwan southern area in jiyuan oilfield of Ordos basin are characterized by low porosity and permeability, rapid change of lithology and facies, and strong heterogeneity. The later work has been restricted because it is in the early development stage, lacking of accurate reservoir evaluation and reservoir parameters. Therefore, it is very important to evaluate reservoir comprehensively and build accurate three-dimensional geological model. This paper takes Chang6reservoir of Baoziwan southern area oilfield as research object, based on comprehensive gelolgical study, with analyzing and selecting for multiple modeling methods, adopt sequential indicator stochastic simulation to build structure model, lithofacies model and phase-controlled attribute model on the basis of sequence stratigraphic framework.The complete3D geological model is built finally, and it could provide geological basis for development plan and adjustment plan of oil fild...
