An oilfield flooding layer fine interpretation and residual oil comprehensive evaluation method

The invention discloses an oilfield flooding layer fine interpretation and residual oil comprehensive evaluation method. The method comprises the steps of flooding layer logging comprehensive identification and evaluation and residual oil evaluation. The water logging comprehensive identification and evaluation method comprises the following steps of 11) establishing a logging interpretation modelfor researching reservoir parameters; 12) according to single well oil testing, commissioning data and logging data, analyzing the flooding layer through a new and old logging comparison method, a resistivity reconstruction method or a freshening factor method; and the residual oil evaluation specifically comprises the following steps of 21) obtaining current use information of a reservoir; 22) determining the distribution of the residual oil of the reservoir in the longitudinal direction; determining the distribution of the residual oil of the reservoir on a section and a plane; and 23) analyzing the well logging te
