Abstract:

According to characteristics and request of reservoir evaluation, as well as the limitation of information in beach area, the method and workflow of integrated reservoir evaluation driven by seismic data is put forward in this paper. Taking the seismic data as restriction, this method makes combination of a set of technology including setting sequence stratigraphic frame, 3D fine structure interpretation, seismic attribute analysis, stochastic simulation seismic inversion, geological modeling based on seismic data, and numerical simulation. The results of structure interpretation and stochastic simulation seismic inversion are the input of 3D quantitative geological model. The integrated predictive model is set through revising by dynamical data. The application to Zhangdong development zone in beach area of Dagang Oilfield generates a better effect. It also provides the reference for the analogical area in reservoir evaluation.

Key words: beach area, seismic, integrated reservoir evaluation, Zhangdong development zone, geological model
