The invention provides a method for recycling crude oil from storage and transportation oil sludge. The method includes the following steps: fully stirring evenly the storage and transportation oil sludge to make a solidification state changed into a semi-flow state, adding low-viscosity oil or recycled light oil, fully stirring, mixing the mixed low-viscosity oil sludge with water, then adding an emulsifier, carrying out ultrasonic emulsification concussion, making a crude oil composition separated with slag particles, allowing to stand, making the slag particles in the obtained mixture settled, allowing the mixed liquid divided into two layers, separating the oil phase and the water phase by a centrifugal method, recycling the oil phase, to obtain the light oil, purifying the water phase for cycle use, and allowing a part of the obtained light oil to be re-mixed with the initial oil sludge. With re-mixing of the recycled oil, viscosity reduction of the initial oil sludge is carried out, so as to be beneficial for cost saving and resource high-efficiency use; the water phase is recycled after purification, so as to reduce water resource consumption; all parameters in the process are systematically and normatively treated, and especially, the oil sludge viscosity is accurately calculated, so that the expected capacity is precise and the applicability is wide.
