A method for calculating oil leakage quantity of a cylindrical valve hydraulic system comprises the following steps: by utilizing real-time data of oil level of an oil pressing tank and oil level of an oil return tank of the cylindrical valve hydraulic system collected by a monitoring system and combining a working state of a cylindrical valve, taking an average value of the oil level of the oil pressing tank and the oil level of the oil return tank within an effective time interval as an effective value for calculation; intelligent and automatic real-time analysis of the oil leakage amount of the hydraulic system is achieved through a calculation method, and oil leakage of the hydraulic system is found in time and early warning is conducted. According to the method, the volume difference of the piston rod of the cylindrical valve under different states (full opening and full closing) of the cylindrical valve is calculated into a calculation formula, so that the result is more accurate; and a cylindrical valv
