摘　　要：气测录井作为石油勘探过程中发现油气显示的最快速、最直接手段,其数据准确性直接影响油气层的评价结果。针对现场工作人员在气测仪标定过程中的很多细节没有引起足够注意,造成标定时产生误差,从而影响气测数据的准确性的问题,从色谱仪器工作原理、标定方法等方面分析了影响气测录井仪器标定准确性的原因,对提高现场气测录井数据准确性具有一定的指导作用。As the fastest and the most direct means of discovering oil and gas shows during oil exploration,the data accuracy of gas logging will directly influence the evaluation results of oil and gas layers.To be aimed at the problems that vari- ous details were not paid enough attention to during the cal- ibration on the gas logging unit on wellsite,thus errors were caused and the accuracy of gas logging data were influ- enced,the paper analyzed the reasons of influencing the cal- ibration accuracy of gas logging unit in view of chromato- graph working principles,calibration methods,which has certain guiding effects on improving the accuracy of gas log- ging data on wellsite.
