云美厚 ,管志宁 .油藏注水开发对储层岩石速度和密度的影响 .石油地球物理勘探 ,2 0 0 2 ,37(3) :2 80～ 2 86 油藏注水开发过程中储层岩石速度和密度的变化是注水时间推移地震监测的基础。注水不仅会引起孔隙流体饱和度的变化 ,而且还会引起储层温度、压力以及孔隙率、渗透率和孔隙流体性质等变化。储层岩石速度、密度的变化是所有这些变化共同作用的结果。本文系统分析了各种因素对岩石速度、密度的影响 ,结果表明 :在油藏注水开采期间 ,除流体替换外 ,储层温度、压力、孔隙率和孔隙流体性质的变化对岩石速度和密度的影响同样是不可忽略的 ,有时甚至是非常关键的。这一研究对进一步开展油藏注水动态时间推移地震监测研究与应用具有重要的指导意义和现实意义。
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 only 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 systematically 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 waterflood stage.The research has important guiding and actual meaning for further studying and application of monitoring reservoir waterflood behavior by time lapse seismic method.
