摘要: 在沉积微相研究的基础上,依据岩心岩性、层理层面构造、粒度及其韵律特征等信息综合观察,分析古水流环境及水动力变化,确定出沉积结构单元界面。同时,通过岩性变化界面及其电性曲线微旋回特征的相关性分析,建立剖面沉积结构单元划分电性韵律标准(如自然电位回返、自然伽马升高、电阻曲线降低或台阶状变化等),进而实现研究区沉积结构单元划分。研究方法对陆相沉积体系及结构单元精细描述具有一定的指导意义。

Abstract: Based on the study of microfacies, in view of the lithology, bedding structure, grain size and rhythm feature, etc., the interface of sedimentary architectural element in Sangonghe reservoir of Cainan oilfield is determined. Throuth analysis of the correlation of lithological interface and electrical curves, the electrical rhythm standard for profile of sedimentary elements such as SP reversion, GR raise, R fall or step-rate curve, etc. are set up, which can be used for detailed description of continental sedimentary system and its architectural elements.

Key words: sedimentary system, microfacies, architectural element, section division, spatial combination
