| 摘 要： | 针对陕甘宁盆地湖泊三角洲沉积体系 ,在关键井沉积相分析的基础上 ,通过研究各沉积微相的测井响应特征 ,应用多元统计分析方法建立了湖泊三角洲相各种沉积微相的测井识别模式 ,实现了单井剖面沉积微相的自动连续识别与解释 ;并在单井沉积微相分析的基础上实现了多井平面解释。应用所开发的软件对长庆油田实际钻井资料进行了处理 ,其结果与地质认识吻合较好。

| Abstract: | For Triassic Yanchang lacustrine delta system in Shan Gan Ning basin, the log response is analyzed for each sedimentary microfacies in key wells, and their recognition patterns are established by multivariate statistical analysis. Thus the sedimentary microfacies on a single_well section can be automatically and continually discriminated and interpreted, by which a multiple_well interpretation may be achieved. The concerned logging data from Changqing oilfield has been processed by using the self_developed software, leading to results coincided well with the interpretation of geological specialist. |
