摘　　要：测井旋回地层学研究主要依据米兰科维奇天文旋回理论,以测井数据作为天文旋回替代指标研究地质、环境、气候等诸多领域的科学问题。目前国内外仍缺少专门针对测井旋回地层学处理分析的软件,本文基于CIFLog软件,使用Java语言开发测井旋回地层学分析模块,包含预处理、天文驱动检验、滤波与调谐等必要功能,并使用理论曲线作为测试数据验证了各功能的有效性。选取松辽盆地松科二井青山口组自然伽马能谱测井钍元素含量数据进行处理,成功识别和提取出13个长偏心率信号周期,估算沉积速率为5.6 cm/ka,并建立浮动天文年代标尺。The study of well log cyclostratigraphy is mainly based on the Milankovitch astronomical theory,using logging data as a proxy for astronomical cycles to investigate scientific issues in geology,environment,climate,and other fields.Currently,there is still a lack of specialized software for the processing and analysis of well log cyclostratigraphy both domestically and internationally.In this paper,a well log cyclostratigraphy analysis module is developed using Java language based on the CIFLog software,which includes necessary functions such as preprocessing,astronomical testing,filtering and tuning.The effectiveness of each function is verified using theoretical curves as test data.We select the Th content data from natural gamma ray spectroscopy logging of Qingshankou Formation in Well SK-2 in Songliao basin for processing and successfully identify and extract 13 long eccentricity signals.The sedimentation rate is estimated to be 5.6 cm/ka,and a floating astronomical time scale has been established.
