Based on the sedimentary features of the fluvial reservoir in the lower member of Minghuazhen Formation of Neo-eerie in the BoHai Bay, precise geologic modeling was used during implementation of drilling program of ODP (Overall Devel-opment Program) for obtaining reservoir depositional pattern, sedimentational microfacies, well-seismic relationship and sand bodies' connectivity. Development data and seismic data of recently drilled developing wells were comprehensively utilized in the method. Besides that, geostatistics and stochastic simulation method were applied. Thanks to the researching, geologic model can be adjusted promptly and improved accurately. Thus, a reliable static geologic model can be provided for optimizing well trajectory and perforating program while drilling. Drilling cases for development well show that geologic modeling while drilling can provide scientific geologic foundation for optimization of developing program and perforating program.
