| 摘 要： | 以提高合成记录制作质量为目标,研究了严重垮塌井段声波、密度测井数据的校正方法,提出了曲线相关计算和曲线正演两种校正方法。前者主要应用在补偿声波失真较小情况下密度测井曲线的校正,后者应用于声波、密度都出现严重失真情况下的曲线校正。上述两种方法在改善地震合成记录质量方面效果明显,已在准噶尔盆地地震合成记录制作中推广应用。

| Abstract: | In order to improve the quality of synthetic seismic records, this paper presents two correction methods for logs correlation calculation and logs forward calibration using sonic-density logging suite. The sonic logging is applied to the correction of density logs in condition of less distortion of compensated sonic logs; the density logging is used to the correction of logs in the case of severe distortion of sonic and density logs. The results applied to the quality improvement of synthetic seismic records in Junggar basin indicate the obvious effects of these methods. |
