摘要
油层内的夹层是影响油田注水效果的因素之一 ,也是影响剩余油研究分布的主要因素。笔者以钻井岩心、测井等资料为基础 ,研究夹层的类型、成因及发育分布特征 ,指出各种类型的夹层与基准面变化过程中A/S比值变化和沉积物补给通量变化关系密切 ,不同级次的基准面旋回和不同沉积微相内夹层的层次类型及发育分布规律不同。文中深入分析了夹层类型与基准面旋回的关系。
The interbeds within the hydrocarbon reservoirs may have exerted an influence on oil field development and residual oil distribution. The types, genesis and distribution of the interbeds are described in detail in the present paper on the basis of well logs, and vary in different base level cycles and sedimentary microfacies. The results of research also show that a close correlation exists between individual interbeds described herein and A/S ratios and sediment flux.
