摘要:

通过对露头、岩心资料的详细分析,在塔里木盆地哈得4油田东河砂岩三级层序内部识别出了5种类型的层序界面,即三级层序界面、准层序组界面、准层序界面、岩层组界面和岩层界面。以常规及地层倾角测井资料的层序界面响应特征研究为基础,提出了各级层序地层界面的测井资料识别标准和方法,包括常规测井曲线识别模式、长窗长处理倾角资料识别模式、倾角测井原始电导率曲线识别模式和精细倾角处理资料识别模式等。应用上述各类测井资料识别层序界面的模式和方法,对全区各井进行了多级层序界面的识别和对比,识别出了5级界面,划分出1个三级层序、1个准层序组、2个准层序(砂层组)、12个岩层组(小层)和50个岩层(单砂体),建立了东河砂岩的高分辨层序地层格架。

Abstract:

Five types of sequence boundaries within the third-order sequence of Donghe sandstone in Tarim Basin are recognized through the detailed analysis of outcrop and core data:the third-order sequence boundary,parasequence group boundary,parasequence boundary,stratum group boundary,and stratum boundary.Based on the response characters of conventional logging and dip logging through sequence boundaries,the standards and methods of sequence boundary identification using logging data are proposed,including the identification model of conventional logging data,the identification model of dip data with long window-length processing,the identification model of original dip-logging conductivity curves,the identification model of precise dip-processing data,etc.By applying the above-mentioned models to the multi-sequence boundary identification and correlation in all wells of the oilfield,five orders of sequence boundaries are identified,and one third-order sequence,one parasequence group(sandbody group),twelve stratum groups(substratum zone) and fifty stratum(single sandbody) are recognized.As a result,the high-resolution sequence stratigraphic framework of Donghe sandstone is established.

Key words: sequence boundary, logging response, Donghe sandstone, Tarim Basin
