Sweet spot evaluation method in shale oil horizontal well drilling process

The invention belongs to the technical field of unconventional oil and gas dessert evaluation, and discloses a quick dessert evaluation method in a shale oil horizontal well drilling process, which comprises the following steps of: firstly arranging drilling and logging data, including drilling time, carbonate content, dolomite, calcite, total hydrocarbon and humidity ratio Wh, and standardizing the data; with explanation data of existing porosity, oil saturation and brittleness as calibration, a shale oil physical property indication parameter A, a shale oil oiliness indication parameter B and a shale oil brittleness indication parameter C are preferably selected according to correlation; by taking the parameters A, B and C as end members, establishing a shale oil dessert type discrimination chart; parameters A, B and C are extracted according to drilling and logging data in the drilling process, real-time discrimination of different types of desserts can be achieved, and reference is provided for rapid opti
