The invention belongs to the technical field of physical method oil extraction simulation experiments, and relates to an experimental device and method for the attenuation testing of ultrasonic wavesin an oil reservoir. The device comprises an ultrasonic generator, a transducer bracket, an ultrasonic transducer, a connecting shaft, a rock core holder, a sand separation plate, a fluid medium tank,a gold hoop and an ultrasonic sound intensity tester; the ultrasonic transducer receives an electric signal transmitted by the ultrasonic generator to generate ultrasonic waves; the ultrasonic transducer is fixed on the transducer bracket through the gold hoop; and the height of the ultrasonic transducer can be freely adjusted; the ultrasonic transducer is fixed on the fluid medium tank through the connecting shaft with threads at two ends; the sand separation plate is inserted into the fluid medium tank; the rock core holder is located in the fluid medium tank and used for fixing a natural rock core; and the ultrason
