ABSTRACT
The core task of reservoir description is to gradually implement the characteristics of reservoir distribution and remaining oil. It is necessary to continuously re-understand the geological characteristics according to the needs of oilfield development adjustment in different stages, to promote the gradual improvement of oilfield recovery. In this paper, the North block of block A after infill drilling is taken as the research object, and the reservoir correlation principle of “cycle analysis, classification, genetic control, and tracking anatomy” is used to finely dissect the reservoir of the target layer in the North block of fault C, and implement the sand body distribution characteristics, permeability characteristics, and reservoir water flooding characteristics of the target layer after infill. It provides an important geological basis for fine adjustment of polymer flooding in class II reservoirs in the block.
