地层岩性识别与油气评价是岩性勘探的主要内容之一,也是数学地质的重要课题.本文用可能性函数和相关算子,建立了一种数学模型(包括计算机实现流程),以期全面应用前人的工作,对地层进行岩性识别和油气评价. Stratigraphic lithology identification and hydrocarbon evaluation are one of the main contents of lithology exploration and also an important issue in mathematical geology.In this paper, a mathematical model (including computer realization process) is established by using the probabilistic function and related operators in order to fully apply Former work, the lithological identification of stratigraphy and oil and gas evaluation.
