Abstract:Based on the basic rule of fluid change in water drive reservoirs,a great number of water drive experiments and statistic results of logging data in two giant oilfields of eastern China, the paper discussed in detail the oil and water migrating feature in a process of water drive for forward and inverse rhythmic reservoirs, summarized the changes of reservoirs in physical parameters (such as porosity, pressure, fluid property) and their influence on acoustic parameters for long-period water-injection recovery oilfield, expounded the feasibility using seismic techniques for monitoring the water drive front in different sedimentary rhythmic reservoirs. The definition of water drive front was given on that bases and the method of time-lapse seismic monitoring water drive front was presented. The feasibility and effectiveness of the method was proved by study of synthetic seismic data of 2-D and 3-D water drive models, at the same time, the distribution of by-passed pocket of oil can better be predicted by seismology if combining the water drive front monitoring with the results of initial reservoir description
