| From the point of evaluating and processing deep well gaslogging, all kinds of gaslogging data influence factor were thoroughly analysised. By eliminating and correcting the false gasloging abnormal data, correcting the influence of oil-in-water drilling fluid, correcting the diversity of engineering parameter, correcting the difference pressure between mud column and formation, a set of process for evaluating deep gaslogging data was established. By this method, the influence factors were minimized and the result data can be used for vertical or horizontal contrasting. Based on the corrected mud logging data, the gaslogging explanation plate and standard, which were suit for deep gas evaluation, were also established. The result were applied to deep well gas interpretation and evaluation in Jilin oil field. Gaslogging evaluation effect were improved greatly and have general guiding meaning for exploration & development of deep gas well.
