摘　　要：为了解在珠江口盆地东部新生界储层砂岩纵横波速度变化特征及其影响因素,利用岩石物性参数自动测试系统(MTS)对在室内温度、压力及饱和气条件下的30个岩样进行了纵横波速度测定。试验研究结果表明:珠江口盆地东部新生界储层砂岩的纵横波速度之间存在明显的正相关关系,横波速度与岩石孔隙度、密度和渗透率的相关性均高于纵波速度。在此基础上,总结了部分适合于珠江口盆地东部新生界储层砂岩的经验关系式,以期为今后珠江口盆地东部的油气勘探开发工作提供一些有价值的基础资料。To understand the changing characteristics and influential and their affecting factors of P-wave and S-wave velocity of Cenozoic reservoir sandstones from Eastern Pearl River-mouth Basin,an automatic petro-physical parameter detecting system(MTS) was used for testing P-wave and S-wave velocity of 30 samples under the conditions of ambient temperature and pressure and saturated gas.The results indicate that the correlation between P-wave and S-wave velocity of Cenozoic reservoir sandstones is positive,and the correlation of S-wave velocity is more related to the porosity,density,permeability of Cenozoic reservoir sandstones than P-wave velocity.The empirical formula,which is suitable for Cenozoic reservoir sandstones,is summed up.It provides valuable data for the oil and gas exploration and development in Eastern Pearl River-mouth Basin.
