摘　　要：为提高测井解释的速度和准确性,提出用时间序列分析方法,对测井曲线作时间序列分析,全面精细的研究不同地质层位测井信号的相似性与差异,并结合多元统计分析中的判别分析方法来区分油层和水层,以解决油气藏描述和工程问题。该方法在对实际资料的测井解释中取得了很好的应用效果,且操作简单,处理速度快。Proposed is time series analysis method which analyzes time series with the logging curves for improving logging interpretation speed and accuracy. Researched is the resemblance and difference of logging curves in various stratum detailedly. An identification and analysis method in the multivariate statistical analysis theories is used to identify water and oil zones, and solve the problems in oil and gas reservoirs description and logging projects. This method is effective in the practical log interpretation and easy in manipulation and quick in data processing.
