Abstract：Reservoir static modeling (RSM) is one of the key points for reservoir engineers to further understand beds and enhance reservoir recovery, which is also the pursuing goal of geophysicists. However great challenges often occur in RSM practical applications due to complexity of geological genesis and diversity of geophysical data. And one of the most critical problems is the integration of the spatial resolution of seismic data and the vertical resolution of well logging data in reservoir model building. Here a new RSM method based on the structural and isochronous stratigraphic frameworks is proposed. The following key techniques are involved: isochronous structural framework interpretation based on the same resolution of seismic and well logging data, isochronous framework interpretation based on seismic sequence stratigraphy and well logging reservoir deposition, reservoir static interpolating modeling with the constraints of structural and depositional isochronous stratigraphic frameworks, and single sand-body interpretation based on modeling result. The proposed approach has been successfully applied to thin inter-bed reservoirs located at the lower wall of overthrusting faults in Junggar Basin, Western China, and its validity has been proved by the oil and gas development in the field.
