Abstract: Reservoir geological modeling is a process to build a three-dimensional digital model which can characterize structural configuration, petrophysical properties and fluid distribution under the initial reservoir conditions. Geological complexity, limitations of modeling methods and unsufficient modeling data lead to the uncertainties of geological understandings and models. In order to improve the quality of geological models and based on the conventional geological modeling methods and history matching technology in numerical simulation, the paper proposes an integrated modeling method which includes multilevel constraints of dynamic and static data, comprehensive utilization of a variety of information and full-process quality control; systematically summarizes the operation techniques for each modeling procedure and the methods of model quality control. The practical application shows that the quality of geological model is greatly improved, the simulation times for history matching of reservoir numerical simulation are reduced and the efficiency is enhanced as well by using the integrated modeling method and the proposed operation techniques
