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 interlayer in the reservoir is one of the factors that affect the water injection effect of the oilfield and also the main factor that affects the research distribution of the remaining oil. Based on the information of drilling core and well logging, the author studied the type, genesis and development distribution of the interlayer, and pointed out that the change of A / S ratio and the change of sediment supply flux are closely related to the changes of various types of interlayer and datum, Different types of basal-level cycles and different sedimentary microfacies within the strata of the type and distribution of the development of different distribution. The paper deeply analyzes the relationship between the type of interlayer and the cycle of datum.
