珠江口盆地碳酸盐岩石物性参数测试与分析

Test and Analysis of Carbonate Physical Parameters in Pearl River Mouth Basin

利用先进的试验设备和配套技术,以岩石物理试验研究为主,针对珠江口盆地(东部)碳酸盐岩储层开展岩石物理参数测试的试验研究工作,直观的展现了碳酸盐岩的密度及纵、横波速度和纵、横波阻抗等物性参数随孔隙度的变化规律,以及纵、横波速度随温度和压力的变化特征,为碳酸盐岩储层预测、裂缝及含油气性检测等研究提供了理论指导和试验依据。

By using advanced experimental techniques and equipments,based on the research of rock physical experiment,rock physical parameters of carbonate reservoirs in the east of Pearl River Mouth Basin were tested in laboratory,by which the rules of P-wave and S-wave velocities,P-wave and S-wave impedances and density changes with the porosity change and the features of P-wave and S-wave velocity with the change of pressure and temperature of carbonate rock were directly displayed.It provides a theoretical guidance and basis for predicting the carbonate reservoirs and studying the fractures and the of oil and gas bearing property.
