Abstract：In the process of waterflood development of reservoir,the changes of velocity and density of reservoir rock are the basis of time-lapse seismic monitoring.Waterfooding can cause not on1y the change of pore fluid-saturation,but also the variation of temperature,pressure,porosity, permeability and fluid properties.The changes of velocity and density of reservoir rock resulted from the joint action of all these factors.Effect of each factor on velocity and density is system-atically studied in the paper.The results show that the effect of the variation of temperature, pressure,porosity and pore fluid properties in reservoir on velocity and density of sandstone can' t be neglected and sometimes is very important,besides fluid substitution during water-flood stage.The research has important guiding and actual meaning for further studying and application of monitoring reservoir waterflood behavior by time-lapse seismic method.
