Zusammenfassung:The invention discloses a shale oil horizontal well development geological reserve control degree prediction method. The method specifically comprises the steps that a shale oil horizontal well full life cycle recovery ratio prediction model is established; the recovery ratio of the full life cycle of depletion type development of the unsaturated shale oil reservoir is calculated through a recovery ratio prediction model by utilizing basic high-pressure physical property parameters of crude oil and gas and compression coefficients of rocks under different pressures; calculating recoverable reserves of all horizontal wells in the target block according to the production dynamic data of the target block; calculating the control geological reserves of the horizontal wells according to the recoverable reserves and the recovery efficiency of all the horizontal wells in the target block; according to the horizontal well control geological reserves and the actual geological reserves, the geological reserve control d
