Abstract：Based on the redevelopment requirement of oilfield with high water cut,the reconstruction of underground recognition system which can be divided into three sub-systems:the reconstruction of underground structure recognition sub-system,the reconstruction of underground reservoir recognition sub-system and the reconstruction of underground fluid recognition sub-system.In this paper,a series of methods are proposed including small-scale fault seismic identification and interpretation method based on breakpoint data of wells,micro structure mapping method confined by reference lamina,alternate thin beds reservoir prediction method based on geological layers constrain and stochastic inversion,geological modeling method constrained by fault,structure and reservoir prediction,remaining oil prediction method based on high quality layer history matching.These methods are applied in a mature oilfield.New recognition on fault,micro structure,single sand body boundary and remaining oil distribution is achieved.
