【摘要】 在对野外深探槽、深探坑的细致观察和描述的基础上 ,结合钻井、测井、实测及室内样品分析等手段 ,运用储层沉积学理论和方法 ,对现代嫩江大马岗段河流沉积体进行了层次界面划分及构形要素分析 ,确定出第一至第五级界面及河道、砾质坝、沙底形、单一侧积沙层、侧向加积沉积、单一侧积泥层、纹层沙席、越岸细粒沉积等 8种构形要素 ,为地下河流相储层精细描述提供了可靠的地质模型更多还原

【Abstract】 On the basis of miticulously surveying and describing the field deep exploration channel and combination with drilling, logging and samples analysis, taking advantage of the theory and method of reservoir sedimentology, this paper reports the results of bounding surfaces and analyzing architectural elements in fluvial deposists of the modern Nen River at Damagang area, classifies the first\|order to the fifth\|order bounding surface hierarchy and distinguishes eight kinds of architectural elements: channel, gravel bar, sandy bedform, single lateral accretion sandy layer, lateral accretion complex, single lateral mud layer, laminated sand sheets, overbank deposits. It provides sound geological model for detailed description of subsurface fluvial reservoirs.更多还原
