利用测井资料划分胜坨油田沙河街组三段下亚段高分辨率层序地层

常规测井资料和新的测井技术为研究高分辨率层序地层提供了可靠的资料,特别是FMI测井资料可以显示出井眼周围岩石的结构和构造等特征。通过岩芯刻度FMI图像,岩芯或FMI图像刻度常规测井曲线,建立利用常规测井资料识别岩性模型,基于高分辨率层序地层学的基本原理,利用测井资料识别长、中、短期基准面旋回,胜坨油田沙河街组三下亚段可分为五个中期旋回、两个长期旋回和若干个短期旋回。

HIGH-RESOLUTION SEQUENCE STRATIGRAPHY OF THE LOWER SUBMEMBER OF Sha 3 IN SHENGTUO OILFIELD BY WELL LOGGING DATA

Well-logging data, especially the data on the modern well-logging techniques provide ideal information for researching high-resolution sequence stratigraphy. The FMI logging data can reveal the constitution and structure of the rocks around the holes. Utilizing the core calibration of FMI imaging log, a model can be built by which we can utilize the well-logging data to recognize lithology. Based on the theory of high-resolution sequence stratigraphy, long-, medium-and short-term base-level cycles can be recognized by using logging data. Thus the third submember of the Shahejie Formation in Shengtuo Oilfield can be divided into 5 medium-term, 2 long-term and several short term cycles.
