【摘要】 纵横波匹配是纵、横波联合反演的基础和关键.本文提出了纵横波时间匹配的方法,主要利用纵横波速度比进行时间匹配,针对开发小层单元,对实际纵波资料提出了采用放大比例尺分频层位解释方法,保证拾取的精度误差在1 ms之内,转换波资料解释主要参考纵波层位与井合成地震记录相结合.同时最终利用标志层和井相结合的精细匹配方法使喇嘛甸工区纵波和转换波达到精细匹配,在此基础上进行纵横波联合反演并取得较好的效果.更多还原

【Abstract】 PP wave and PS wave matching is the basis and crucial portion of joint inversion.This paper presents a PP wave and PS wave time matching method,the method main use PP wave and PS wave velocity ratio to conduct time matching.At development small scale,presents the enlarged scale horizon interpretation method to ensure picking accuracy error within lms,converted-wave layers interpretation primarily refers to PP wave horizons and seismogram.Finally,utilizing the combination of mark layer and wells to achieve fine matching of PP wave and converted-wave data in Lamadian work area,based on this method to conduct PP wave and PS wave joint inversion and gain good effect.更多还原
