本文介绍天然地震透射转换波(PS)测深资料数据处理软件包——DSCW86。DSCW86由数字滤波、震相识别及资料分析解释组成。数字滤波部分包括:低通滤波、偏振滤波、频率加强滤波、相关滤波及叠加处理等。各种滤波方法的综合应用可以较大程度地提高原始记录的信噪比及分辨率,从而为准确地识别转换波震相提供了基础。在震相识别中采用人机联合的方法,通过偏振分析、功率分析及相位追踪等技术大大提高了震相识别能力。DSCW86还包括所有分析解释图件的计算机描绘,从而减小了工作量,提高了工作效率。
This article describes the natural seismic transmission converted wave (PS) sounding data processing software package - DSCW86. DSCW86 consists of digital filtering, phase identification and data interpretation. Digital filtering includes: low-pass filtering, polarization filtering, frequency enhancement filtering, correlation filtering and overlay processing. The comprehensive application of various filtering methods can greatly improve the signal-to-noise ratio and resolution of the original record, and thus provide a basis for accurately identifying the phase of the converted wave. In the phase identification using human-computer combined method, through the polarization analysis, power analysis and phase tracking techniques to greatly improve the phase identification ability. The DSCW86 also includes a computerized depiction of all the interpretation diagrams, reducing the workload and increasing productivity.
