The invention discloses a hot air type combustor. The hot air type combustor comprises a fuel butterfly valve, an air ventilation door, an adjusting mechanism assembly, a cooling air inlet and a combustor shell. The combustor shell comprises an outer shell body, an inner shell body and non-asbestos alumina silicate fiber cotton. An ignition needle device comprises an ignition needle and a ceramic bar installed outside the ignition needle. The bottom of the air ventilation door is connected with a ventilation door assembly. The ventilation door assembly comprises a ventilation door frame, a ventilation door shaft, a temperature sensor and a servo adjusting motor. The combustor shell is further provided with a fire detection thermal insulation sleeve. The fire detection thermal insulation sleeve comprises a flame monitor and a thermal insulation glass cover. A combustion head adjusting barrel assembly is arranged behind the fuel butterfly valve and comprises an air pressure adjusting barrel, an adjusting pull rod and a fuel gas mixing head. The hot air type combustor achieves the aim of temperature resisting of the ignition needle and the flame monitor, the temperature of the outer surface of the combustor is reduced, and pressure adjustment on the ventilation door and the fuel combustion head of the combustor can be automatically carried out along with the temperature change.

The present invention is a heavy oil recovery method integrating heat injection recovery and mechanical oil recovery. The specific steps are: S1, preparatory work; S2, running a combined heat injection string in the wellbore; S3, after running the heat injection string, Install the christmas tree, and after the christmas tree is installed, implement the heat injection process; S4, self-spray production, measure the temperature of the output fluid, and provide a basis for the subsequent selection of the temperature resistance level of the mechanical mining tool; S5, lower the mechanical mining tool; S6, Machine mining. In the present invention, the large-diameter wellbore and the heat injection string are lowered first, and then heat injection is performed; after the heat injection and self-spraying production are completed, no dynamic heat injection string is required, and the oil tree is not required to be dismantled, only the coiled tubing is needed to connect The mechanical mining tools are sent to the predetermined position in the heat injection pipe string for sealing, and then the mechanical mining can be realized, which solves the contradiction between the resistance of the mechanical mining tools and the high temperature of the thermal injection oil production under the existing technical conditions. Oil development provides an important technical means.

The invention discloses a high-temperature-resistant displacement sensor probe manufacturing device and method based on a planar coil, which includes a displacement control unit, a wire feeding unit and a winding drive unit arranged on the displacement control unit, and a detachable installation with the winding drive unit. Planar coil fixed unit. The metal wire is sent into the middle of the fixed clip through the wire feeding unit and fixed on the winding shaft. The winding motor drives the winding shaft to rotate and is wound into a planar coil between the two fixed clips. The planar coil and the ceramic sheet are bonded with ceramic glue. for encapsulation. The invention has controllable cost, high reliability, and is convenient for batch production. The coil material, wire diameter, and coil size can be independently selected to manufacture suitable planar inductance coils, and the problems of making and forming non-self-adhesive planar coils are solved. The planar inductance sensor probe made of high temperature resistant materials can be used for non-contact measurement in harsh environments above 1000°C, which solves the problem of sealing processing and temperature resistance of sensor probes in extremely high temperature environments.
