| 8. | By means of the results obtained , such as the quantificational relationships between the rock ultrasonic wave parameters and the important formation conditions like pressures , and the half - quantificational relationships between the rock ultrasonic wave parameters and porosity and density of those rocks , and the relationships between rock ultrasonic wave parameters and the composition of rocks , we established the corresponding relationships between the ultrasonic wave parameters and depth under the main formation conditions ( indicating temperature and pressure gradient ) in tertiary of zhujiangkou basin , which should be very useful for the geophysical exploration
获得了岩石声学参数与压力等重要地层条件之间的定量关系，岩石声学参数与孔隙度和密度之间、以及与岩石组成之间的半定量关系，并建立了在珠江口盆地东部第三系主要地层条件下(指温度梯度和压力梯度)不同岩石类型的主要声学参数与深度之间的对应关系，该关系可为地球物理正演模型的建立提供基本参数、并为地震反演提供新的约束机制。 |
