The 3D Visualization of Geological Modeling in Chengbei Oilfield based on Phased Constraint Conditions

摘要

This paper takes Chengbei oilfield which lies in Bohai Bay as the research object, by means of the reservoir fine description, and on the basis of the modeling method to undertake the study of geological modeling based on the sedimentary microfacies constrains. For tectonic features and geological characteristics of Chengbei oil field, and based on the results of well logging interpretation, the author starts the study of sedimentary microfacies by the means of stochastic simulation quantitatively, applying the distribution of the restricted logging reservoir parameter according to the results of sedimentary microfacies research. The author establishes 3D visualized geological modeling which is a need to Reservoir numerical simulation research and calculated the geological reserves continually and then come to verify the expected method is feasible. The paper also provide a geological basis for the later reservoir numerical simulation and designing adjusting plan of reservoir exploitation.
