Abstract
A method is disclosed for evaluating and predicting a shale oil enrichment area of a fault lacustrine basin, comprising: obtaining materials and key data; determining a source-reservoir configuration relationship according to a longitudinal superposition relationship of different types of rock in a lithology profile and establishing a single-well lithofacies model; in the single-well lithofacies model, using a dolomite-to-formation ratio and a TOC average value to form a dolomite-to-formation ratio contour map and a TOC contour map, and superposing the dolomite-to-formation ratio contour map, the TOC contour map and a source-reservoir configuration relationship plane distribution map to form a lithofacies plane distribution map; on the basis of the lithofacies plane distribution map, superposing a vitrinite reflectance contour map and a dolomite thickness contour map to obtain a corresponding evaluation and prediction map of the shale oil enrichment area of the fault lacustrine basin.
