摘　　要：本文主要阐述了中国大陆科学钻探工程现场实验室采样和分析流程。介绍了现场气体分析方法和异常气体采集装置的使用及其对气体分析结果的影响情况,并比较了气体分析的准确度和精密度。对比了4种现场泥浆样品处理方法,特别是后两种方法,分别从准确度和精密度、上层清液放置时间和泥浆处理时间等不同因素对泥浆分析结果的影响进行了分析比较。The paper mainly deals with the sampling methods and gas and mud analytic procedure in the field lab of the Chinese Continental Scientific Drilling project （CCSD）. The use of the degassing equipment and anomalous gas collecting equipment and their influence on the results of gas analysis are described, and the accuracy and precision of gas analysis are compared. Four different methods of on-site mud sample treatment, especially the last two methods, are discussed. The influences of different factors, such as the accuracy and precision, duration of placement of clear fluids in the upper layer and duration of mud treatment are compared.
