【摘要】 根据Ｂｅｒｒｙｍａｎ散射模型及弹性波理论，计算了纵、横波速度与复合介质密度、白云石（或方解石）含量的关系。并且对１７０余块碳酸盐岩样品的纵波速度与方解石、白云石含量及泥质含量的关系进行了实验考察。研究认为，孔隙度是影响纵波速度的最主要的因素；泥质含量比孔隙度对纵、横波速度的影响小．但泥质含量要比方解石或白云石对纵、横波的影响大得多，理论考察和实验研究的结果一致。更多还原

【Abstract】 This paper proposes a model for calculating the contents of calcite, dolomithe and water in pores. Based on Berryman’s scattering theory, the relationship of compressional and shear wave velocities with the densities and contents of calcite and dolomite are studied. Experimental investigation on 170 carbonate rock samples was carried out. The results shows that porosity of rock is the main factor affecting the velocity of longitudinal wave. The shale content has a smaller affect on the wave velocity than shale content.更多还原
