【摘要】 在陆相层序地层研究中,多条录井地层"砂地比"的对比分析是判断物源方向、揭示沉积环境、辅助层序地层划分及岩相古地理研究中的一项重要指标,为地学研究中最基本的方法。本文使用Access数据库技术以层序为单位实现了海量录井地层"砂地比"的快速计算,与传统的方法相比,提高了工作效率,增强了数据的准确性和可靠性。实践证明,该方法是一种切实可行的科学计算方法,可以在地学研究中推广使用。更多还原

【Abstract】 Comparative analysis of sandstone content in terrestial strata is an effective method to determine directions of sources and to reveal sedimentary environments in sequence stratigraphy studies.It is also an important index that is used to delineate sequence stratigraphy and lithofacies in palaeogeography studies.This article uses an Access database to achieve fast calculation of sandstone radio using massive logging data of sequence stratigraphy.The new method improves efficiency and enhances data accuracy and reliability as compared with the traditional methods.It is proved that the method is a feasible means of scientific compuation and can be used in other earth science research.更多还原
