【 摘 要 】

In order to meet the needs of fine adjustment of oilfield development in ultra-high water cut period, the heterogeneity characteristics of reservoirs after well pattern infilling are studied, and the reservoir heterogeneity is evaluated qualitatively and quan itatively. The target block is dissected by the method of cyclic correlation,and the type of sedimentary environment and the number of sedimentary units of the target reservoir are determined. At the same time, through the permeability characteristics of each sedimentary unit, the heterogeneity characteristics of sand body in three aspects, i.e. interlayer, plane and intralayer, are analyzed, which provides an important basis for fine water control and tapping potential of target reservoirs in this block.
