Shale oil horizontal well fracturing layering method and device

The invention discloses a shale oil horizontal well fracturing layering method and device, and relates to the technical field of shale oil reservoir fracturing geological design, and the method comprises the following steps: determining a test oil well section according to a dogleg degree in front of a specified position point, an artificial well bottom position and a logging evaluation result; determining a fractured well section in the test oil well section according to the oiliness of the reservoir and the type of the reservoir; according to reservoir condition parameters and rock mechanical parameters, a fractured well section with similar reservoir conditions and rock mechanical properties is divided into fractured sections, and the number of the fractured sections and the length of each fractured section are determined; according to the fracture pressure difference, the casing coupling position, the reservoir category, the fault displacement, the well leakage, the dogleg degree and the distance to the b
