Abstract
The invention relates to a sand and gravel heat storage type high-efficiency heating furnace for an oil recovery well and a use method. According to a technical scheme, a chimney is arranged on the top of the shell, an inner chamber is arranged inside the shell, the inner chamber is a cylindrical body with the bottom connected with a bottom plate, and the connecting bottom plate of the inner chamber is welded at the middle and lower part of the inner wall of the outer shell, and a coil pipe coils in an annulus between the shell and the inner chamber in a dual rectangular shape, and the annulus is further filled with heat-storage and heat-conducting sand and gravel . The high-efficiency burner is placed at a lower chamber mouth of the inner chamber. The high-efficiency heating furnace has the beneficial effects as follows: the annulus is filled with the heat-storage and heat-conducting sand and gravel, the coil pipe is heated indirectly and can be uniformly heated, and the coil coking phenomenon caused by the high temperature is avoided, and when the heating furnace fire is out, the residual temperature of the heat-storage and heat-conductive sand and gravel can be kept for a long time, so that the phenomenon of pipeline freezing-blocking of the oil recovery well is effectively avoided. The top of the coil is 'water' type structure and is exposed to a heating space inside the inner chamber, so that the heating efficiency is increased. Because of the distance from the flame, it will not cause the coil over-heated and coking phenomenon.
