摘　　要：在油气勘探开发过程中,地震勘探是油气田勘探开发的重要手段,测井资料的综合分析和解释是勘探开发的关键环节,以地质学、沉积学为基础开展井震联合反演是提高勘探开发的重要途径。地震反演是测井与地震信息融合的过程,其结果往往得不到理想的效果,问题的关键是测井信息与地震信息未能有效统一。重点阐述了井震结合过程中,测井资料一致性处理问题,提出利用标准泥岩段频率分布一致性法对测井曲线进行校正,以消除测量环境差异导致的测井曲线误差,使测井资料与地震资料达到最佳匹配,从而提高地震反演效果。In the process of oil and gas exploration and development,the seismic exploration was the most important means of oil and gas field exploration and development,the comprehensive analysis and interpretation of logging data were the key link of oil and gas exploration and development. While the well-seismic joint inversion was the important way for improving oil and gas exploration and development based on geology and sedimentology. The joint inversion was fuse process of logging and seismic data. The inversion result was not ideal,the key was that the logging and seismic data were not unified effectively. The process of well-seismic joint and issues of the consistency of logging data were expounded emphatically. It is proposed that the consistency method of standard mudstone frequency distribution is used to correct logging curves to remove the errors of logging curves induced by detecting difference,thus the logging data would be optimally matched with seismic data for improving the result of seismic inversion.
