Novel oil-field fishing tap device

The utility model relates to an oil-field fishing device, particularly a novel oil-field fishing tap device. The technical scheme is as follows: the novel oil-field fishing tap device comprises an upper adapter, a fishing body, and threaded-joint threads formed in the inner cavity of the fishing body; the lower end of the fishing body is in threaded connection with the body of a centralizer; a plurality of centering teeth are formed in the inner cavity of the body of the centralizer; and a guide shoe is connected at the bottom of the body of the centralizer. The novel oil-field fishing tap device has the benefits that the body of the centralizer is connected at the lower end of the fishing body and the centering teeth are arranged in the inner cavity of the body of the centralizer, thereby taking the centering function; and besides, the thread making operation is easier and the fishing success rate is higher.
