description The invention provides a device for washing a mud cake on the inner wall of a drill rod, and relates to the technical field of geological drilling rope coring drill rod inner wall mud cake removing equipment. The device solves the technical problem that a cleaning device is easy to fail in sealing and complex in structure. The device for washing the mud cake on the inner wall of the drill rod comprises an outer cylinder, wherein the outer cylinder is of a hollow structure, the bottom of the outer cylinder is sealed, and a liquid flow main channel for allowing high-pressure liquid flow to passtherethrough and a liquid flow branch channel communicating with the liquid flow main channel and capable of conducting branch guiding on the high-pressure liquid flow are formed inside the outer cylinder; the device for washing the mud cake on the inner wall of the drill rod further comprises static nozzles and movable nozzles which are detachably arranged on the outer cylinder and communicate with the liquid flow branch
