摘　　要：准噶尔盆地彩南地区利用常规气测解释图版解释符合率较低。该文在分析彩南地区气测组分特征的基础上,结合常规气测解释方法,对已有的气测和试油资料进行了探索性的研究,对双对数法和气体烷烃比值(3H)法进行了分析,研制出了C1与C2的对数比值与烃平衡比(Bh)的解释图版及划分标准。应用实践表明,该方法的解释符合率与常规方法相比有大幅度的提高,对于不同地区地层地质与气测组分特征,建立地区性解释图版具有一定的指导意义。The interpretation coincidence rate with the conventional gas logging interpretation chart in Cainan area of Zhunger Basin was lower. On the basis of analyzing the characteristics of gas logging composition in Cainan area, combined with the conventional gas logging interpretation method, the paper carried out probing study for current gas logging and oil testing information, analyzed double-log method and gas alkane ratio(3H)method, and developed the interpretation chart and classification standard of the double-log ratio for C\-1 and C\-2 and hydrocarbon balance ratio([WTBX]Bh[WTBZ]).The practical application showed that the interpretation coincidence rate had been highly improved compared with the conventional method, it had guiding meaning for establishing area interpretation chart according to formation geology and gas composition characteristics for different areas.
