Disclosed is a thermal well-flushing fluid director which is provided with a lower fluid direction cylinder. The thermal well-flushing fluid director is characterized in that the upper end of the lower fluid direction cylinder is connected with a fluid direction bushing through jackscrew support sleeves circumferentially and uniformly distributed and fixed, the upper portion of the fluid direction bushing is fixedly connected with a rubber cone cylinder by means of vulcanization, the maximum outer edge of the rubber cone cylinder is in contact with the inner wall of a bushing, a micro clearance is formed from the inner end of each jackscrew support sleeve to the outer wall of an oil tube, an inner thread is arranged on each jackscrew support sleeve, an upper jackscrew is connected in each jackscrew support sleeve in a threaded manner, and the inner end of each upper jackscrew is in contact with the outer wall of the oil tube; the lower end of the lower fluid direction cylinder is in threaded connection with lower jackscrews in a circumferential even distribution manner, and the inner end of each lower jackscrew is in contact with the outer wall of the oil tube. By the thermal well-flushing fluid director, paraffin removal effect of the oil tube is improved remarkably, and energy and water are saved.
