Abstract

Abstract: The geophysical properties of fluid flow in porous rock were investigated.The calculation models for acoustic property of three types of fluids were built.The relation of the acoustic properties of fluids with rock temperature and porous pressure was determined.A mathematical model for mixed fluid of gas and oil was also given.These models can be used to calculate the acoustic properties of oil,gas and brine and to describe the effects of intrinsic properties of fluids and external physical properties such as pore pressure and rock formation temperature on acoustic properties of fluids such as velocity,density and modulus.The accuracy of predicted properties is in good agreement with the real measured data.

Key words: fluid, acoustic property, wave velocity, fluid density, fluid modulus, mathematical model

摘要： 为了研究孔隙流体的声学性质,建立了3种流体性质的数学模型,分析了流体声学性质(速度、密度、体积模量)与地下岩石孔隙温度和压力的关系,同时还给出了两种流体混合状态下声学性质数学模型。为了验证模型的可靠性,将天然气的实测数据与数学模型计算结果进行了对比。结果表明,模型计算结果与实测数据吻合较好,误差为0.2%～2%,能满足实际生产的需要。
