摘　　要：煤层气测井质量的好坏直接关联到后续工序能否正常开展,为此要求煤层气测井监理对所测参数曲线具有较强的解读和鉴别能力。然则作为新兴行业,煤层气测井监理尚未形成统一的理论和方法。通过分析打煤孔测井与煤层气测井的共性与差异,认为打煤孔测井监理与煤层气井测井监理的工作方法大相径庭,前者重点在于煤层,后者除要求煤岩解释外更侧重于曲线本身的可信度评价。根据煤层气测井监理的特点,提出了对不同测井曲线进行监理时应重点检查的内容及相应的改进措施。The quality of CBM well logging is direc.tly connected with if the subsequent handlings can be carried out normally. For this reason, well logging supervision personnel should have proven unscramble and resolving abilities on parameter traces logged. Then, as a newly developed profession, the CBM well logging supervision has not yet formed a unified theory and methodology. Through analysis of similarities and differences between coal logging and CBM logging, has considered that working methods of coal logging supervision and CBM logging supervision are widely divergent; the focal point of the former is on coal seams, while besides coal and rock interpretation, the later is more focused on reliability evaluation of logging traces per se. According to the peculiarity of CBM logging supervision, the focal contents of inspection and corresponding improving measures on different logging traces put forward.
