The invention relates to a continental facies matrix type shale oil reservoir strata layer and layered shale structure fine evaluation method. The method mainly solves the problem that an existing method cannot achieve fine evaluation of a lamina layer and a layered shale structure of a large freshwater lake basin continental facies matrix type shale oil reservoir and the basic problem of shale oil exploration. The evaluation method comprises the steps that shale oil exploration drilling coring, lithology and lithofacies accurate description and stratified shale and stratified shale matched geological experiment analysis methods are used for conducting millimeter-scale, micron-scale and nanometer-scale three-scale fine evaluation on stratified shale and stratified shale structures; four combinations of a ternary structure and four combinations of a binary structure of the matrix type stratified shale are determined for the first time; according to the method, the lithology and reservoir performance of shale o
