Abstract: The precision of a geologic model is the most critical step for fine reservoir description, not only relating directly to the accuracy of numerical reservoir simulation, but also affecting the validity of a prediction scheme. The Cretaceous reservoir in Lianmuqin oil field is one with complicated fault system and edge-bottom water. Petrel software is used for the 3D geologic modeling in this block, which features a full use of drilling, seismic, well log and stratigraphic correlation data. This paper presents a practical 3D geologic model through seismic inversion, integrated with lithofacies curves and porosity and permeability curves as well as evaluations of various stochastic models and modeling methods available

Key words: Tuha basin, Lianmuqin oilfield, reservoir, geologic model
