Beschreibung
Zusammenfassung:	The invention discloses a shale oil reservoir full life cycle recovery ratio prediction method and system, and belongs to the technical field of recovery ratio prediction in oil and gas field development. Based on shale oil reservoir failure type development formation pressure changes, the shale oil development full life cycle is divided into two stages of elastic drive and solution gas drive, and a shale oil reservoir failure type development full life cycle recovery ratio prediction model is built by combining the material balance principle. Relevant basic parameters of the new model are obtained through fluid phase state simulation and rock core physical simulation, and the recovery ratio is accurately calculated. Compared with a numerical simulation method, the shale oil reservoir full life cycle recovery ratio prediction method and system have the advantages that the shale oil development process drive type changes and the material balance principle are combined, geological modeling and numerical simulat
