摘要 以储层构形理论为指导,针对三角洲前缘河口坝沉积特点,在常规储层层次分析对比法的基础上,运用"标准层分级分类定成因,基于成因分区精细对比"的方法,利用稳定隔夹层为标志层的划分对比手段,达到了对永3-1断块沙二下5砂组河口坝砂体小层、单砂体、增生体三个级别构形界面的精细划分。得出了单砂体、增生体级别构形界面对剩余油分布具有控制作用这一结论,划分成果应用到永3-1断块面向单砂层的立体开发中,为剩余油的挖潜指明了方向。 With the instruction of configuration theory,the delta front debouch bar of the Sand Unit 5 of Es2 low in the Yong 3-1 fault block of the Shengli oilfield has been finely divided into three configuration interfaces of subunit,single sand and accretion body by using the principle of 'genesis is determined by classification and gradation of marker beds,sublayers are finely correlated based on genesis partitions',with stable intercalations as marker bed based on the conventional method of hierarchy analysis.It is believed that the configuration interfaces of single sand and accretion body have a control action on residual oil distribution.This achievement on division is applied to tridimensional development of single sand bodies in the Yong 3-1 fault block and is helpful to producing residual oil.
