Using the combined layout chart of two components, the data acquisition by compressional wave and converted wave is considered effective and economic. In this paper, a computing method for travel time curve of the converted wave is suggested, based upon which several processing modules for converted wave, such as constant velocity scanning, normal moveout correction, as well as a specific processing sequence were established for processing the field data.

Converted wave will have wide application prospects because of convenient data acquisition and low cost. Asymmetric converted-wave trace gathering is made according to v_p/v_s ratio. The stack velocity of the converted wave is obtained using hyperbolic fitting method. A_p/A_(s) ratio section is made fay compressing converted wave. v_p/v_s ratio section and Poisson's ratio section are produced after P-wave horizons are correlated with convertei-wave horizons. Using these methois, we analysed and processed the real converted-wave data in YM aea and acquired some useful infomations which can not be obtained in common P-wave exploration.

转换波采集方便、成本较低,有着广阔的应用前景。本文按纵横波速度比对转换波进行不对称抽道集,然后采用双曲线拟合方法求取转换波的叠加速度,并提出用压缩转换波的办法制作纵波和转换波的振幅比剖面;在确定纵波和转换波的层位对应关系之后,求取速度比及泊松比剖面。利用上述方法对YM地区的实际转换波资料进行分析和处理,获得了一般单纯纵波勘探所得不到的有用信息。
