对美国岩芯公司的声速测量仪、中国科学院的20—8型瞬态记录仪和IBM系列微型机进行了联接,并完成了对频率为1H_z—5MHz的瞬态信号的A/D转换、波形存贮和信号分析等一整套信息处理系统,不仅能记录纵横波在岩石中的传播时间,而且能记录其幅度,进行幅频特性的研究,为了解声波在岩石中的传播特点,探讨声参数与储油物性之间的关系提供了强有力的工具。
Acoustic velocity measuring instrument from American Core Company, CAS 20-8 Transient Recorder and IBM series microcomputers were connected, and the A / D conversion of the transient signal with the frequency of 1H_z-5MHz was completed. The waveform Storage and signal analysis of a set of information processing systems, not only can record longitudinal and shear wave propagation time in the rock, and can record the amplitude of amplitude-frequency characteristics of the study, in order to understand the acoustic wave propagation characteristics in rock, acoustic parameters And the relationship between the physical properties of the reservoir provides a powerful tool.
