Abstract:

With the need of developing mature oilfields with high water cut, the present paper reviewed the development history of reservoir geophysics techniques and proposed the reservoir geophysics techniques in developing mature oilfields with high water cut as a new research area of geophysical prospecting for petroleum in China. The paper enumerated ten geological issues for the application of reservoir geophysics techniques to mature oilfields with high water cut and discussed some important cognition problems including the suitability of seismic attribute analysis technology, the necessity and feasibility of log curve reconstruction of reservoir physical properties, the application of well data to seismic inversion and the plotting units of production seismology. Based on studies of the recognition of low-order faults, the interpretation of microstructures and the prediction of laminated interbed reservoirs, the paper, by taking an oilfield in eastern China as an example, showed the necessity and feasibility to apply reservoir geophysics techniques in developing mature oilfields with high water cut.

Key words: oilfield with high water cut, prediction of remaining oil, enhancement of oil recovery, reservoir geophysics, production seismology, seismic inversion, reservoir prediction
