PURPOSE: A simulation method using a vertical U-shaped pipe and a horizontal pipe for grasping effects of a bent pipe to a pipeline transport process of carbon dioxide marine geological storage is provided to simulate changes in an external environment condition caused by properties of the heat transmission of soil where the pipe is buried and a seasonal change by using, thereby enabling to grasp a pressure decrease and heat transmission properties when transporting carbon dioxide. CONSTITUTION: A simulation method using a vertical U-shaped pipe and a horizontal pipe for grasping effects of a bent pipe to a pipeline transport process of carbon dioxide marine geological storage(1) is as follows. A first evaporator(2) heat exchanges liquid carbon dioxide supplied from the liquid carbon dioxide storage with air, thereby converting into gaseous carbon dioxide. A first reciprocating high-pressure(3) compresses the gaseous carbon dioxide at high pressures. A first accumulator(4) reduces the pressure pulsation of the gaseous carbon dioxide of high pressures. A high pressure heat exchanger(6) converts the decompressed carbon dioxide into liquid carbon dioxide. A liquid receiver(7) receives the liquid carbon dioxide of high pressures and prevents the liquid carbon dioxide from evaporated. A first flow rate control valve(10) regulates a flowing area of the liquid carbon dioxide, applies flow resistance, and regulates a flow rate of the carbon dioxide supplied to an experimental unit(23). A reactor receives the liquid carbon dioxide and receives extra water from a water supply unit, thereby performing a hydrate reaction experiment.
