| description | The invention relates to the technical field of oil-gas field development, in particular to a classification evaluation method for residual oil in an extra-high water cut period. The method comprises the following steps that target oil reservoir development geological data are collected, and a geological model of a target oil reservoir is constructed; carrying out target oil reservoir development numerical simulation, dividing each grid unit by adopting a geologic model space, and obtaining an extra-high water cut period remaining oil space distribution result; grid unit characteristic parameters and remaining oil data are extracted, and a remaining oil classification evaluation index system is constructed; and performing unsupervised clustering analysis on the remaining oil, and determining a remaining oil classification evaluation limit. According to the method, classification evaluation of the remaining oil in the extra-high water cut period is achieved, and the blank in the prior art is filled.
