The invention discloses an oil string thread and sealing face damage acoustic detection method, which is applied in the technical field of thread sealing detection. The method comprises the following steps of: arranging a moving fixture in a way of pressing driving wheels and driven wheels of the moving fixture onto the outer surface of a tubing coupling; arranging a transmitter/receiver and a receiver/transmitter; arranging a correction assistor onto an axial moving transducer fixture; making the moving fixture perform circumferential movement on the outer surface of the tubing coupling; detecting the damage condition of a thread sealing surface in the coupling; performing primary detection by using the transmitter/receiver and the receiver/transmitter respectively, and then performing correction detection on primary detection results by using the correction assistor; and judging the damage condition of the thread sealing surface of an oil string according to correction detection results. The method has the advantages of detecting whether the thread sealing surface of a joint is damaged or not after an oil tube is buckled, avoiding the damaged joints being lowered into a well, ensuring the security of the oil string, further ensuring the production security of the whole well and improving the production efficiency.
