Update Geological Model Seismically

Geological modeling technology is one of the important means for reservoirheterogeneity and is also the basis of the reservoir model. The quality of the reservoirgeological model have a direct impact on the reservoir quality of the digital-to-analogmodel and further affect the development or scientific nature and effect of the adjustmentprograms. Reservoir geological model was established on the basis of the geologicalstudies or fine reservoir description analysis, evaluation of the quality of reservoirgeological model is applied to an important part of the to establish reservoir model.Reservoir geological model is no physical mechanism fitting way of geophysicalinformation and therefore to establish from the rock model, seismic forward, andobservation seismic response fitting model modified cycle process is more in line withthe analog necessary observational data of the road. This will undoubtedly make theheterogeneity characterization more intuitive, and provide the basis of the model for thesubsequent distribution of the remaining oil awareness.In this paper, seismic forward method to update the geological model and testing toestablish the geological the model returns seismic and update the model of the newprocess. Through the rock model calibration, inspection and correction makes thegeological model can effectively combine with seismic.Analysis of reservoircharacteristics determine the geological sensitive parameters of the model under theguidance of the regional deposition patterns. The geological model is closer to thedevelopment phase of the well, seismic data and geological-law.
