The invention provides a calculation method of the oil content height of oil deposits of sandy conglomerate structures. The method includes the steps of counting up the thickness of the sandy conglomerate at a target layer, and drawing a sandy conglomerate thickness contour map; drawing an oil deposit profile map including trap peak points and spill points of the oil deposits, and counting up geological parameters of all oil deposits; conducting correlation analysis on each geological parameter and the oil content height separately, and creating a single-factor calculation formula of the oil content height and each geological parameter separately; conducting data sorting, preferentially selecting the geological parameters which are high in correlation degree with the oil content height, and creating a main controlling factor statistical table of the oil deposits of the sandy conglomerate structures; adopting a multiple linear regression method, and creating a linear mathematic relationformula between the oil content height and each main controlling geological factor. According to the calculation method of the oil content height of the oil deposits of the sandy conglomerate structures, the oil content height of the oil deposits of the sandy conglomerate structures at shallow layers can be determined, and therefore a better guidance can be provided for oil-gas exploration and reserve declaration.
