| Abstract: | To counter interference of external and secondary circulating gas in interpretating oil gas zones,the paper raised to eliminate the interference by difference chromatography,introduced the concept and realizing methods, analysed the measuring condition and affecting factors,and provided the samples of using it in gas logging.At the prerequisite for meeting the needs of difference chromatographic measurement,the method is of benefit to gaslogging interpretation and oil-gas-water zone evaluation.It provides a way for half quantitative and quantitative gaslogging interpretation. |
