摘要

水平井合成地震记录制作的原理与直井相同,但具体的制作方法应根据水平井的钻井轨迹和测井曲线与地层的配置关系,分段对测井曲线进行井斜方位校正和地层埋深校正,以及曲线反向和角度转换等处理,以制作出符合地震反射原理的高质量合成地震记录,完成水平井合成地震记录的层位标定.

Abstract

The principle of seismogram synthesis for horizontal wells is the same as for vertical wells except for that the correction for well deflection and the buried depth of strata as well as the processing for well logs reversion and incident angle transform are segmcntally conducted based on the deployed inter-relationship between the trajectory of a horizontal well and its logs so as to synthesize high quality seismograms which obey the principle of reflection seismics and attain the stratum demarcation for horizontal well synthetic seismograms.
