摘　　要：运用高分辨率层序地层学原理和方法,综合利用岩心和测井资料建立起吉尔嘎朗图凹陷宝饶洼槽腾格尔组基准面旋回的地层响应模型,通过对钻、测井资料和三维地震资料的综合分析,在腾格尔组识别出3个长期基准面旋回(三级层序)LSC1、LSC2和LSC3,建立了腾格尔组高分辨率等时地层格架。在等时地层格架内,研究基准面旋回与砂体发育规律的内在联系。Based on core and logging data, a bed response model of datum level cycle for Tengor Fm in Baorao low land in Jirgalangtu sag is built by using the principles and methods of high resolution sequence stratigraphy. Three long -term datum cycles (third grade sequence), including LSC1, LSC2 and LSC3 are identified in the Tengor Fm through comprehensive analysis of drilling, logging and 3D seismic data and a high resolution isochronic strati-graphic framework is built for Tengor Fm. The intrinsic relationship between datum level cycle and the pattern of sandbody development is studied in the context of the i-sochronic stratigraphic framework.
