titleOfInvention | A nitrogen electric heating method and system for in-situ pyrolysis of oil-rich coal |
abstract | The invention discloses a nitrogen electric heating method and system for in-situ pyrolysis of oil-rich coal. One end of a second gas transmission pipeline is connected to a high-temperature and high-pressure nitrogen storage tank, and the other end extends into a heat injection well, and passes through a heating cable heating structure and a heating structure in turn. The electromagnetic induction heating structure is connected to the variable frequency power supply device and the cooling system, and the heating cable heating structure, the variable frequency power supply device and the cooling system are respectively connected to the power supply and the control system; high temperature and high pressure nitrogen enters the heat injection well through the second gas pipeline, The heating structure is used to heat the second gas pipeline; the heat injection well is connected to the production well through the fracture, and high-temperature and high-pressure nitrogen enters the fracture; the mixed gas generated by the thermal decomposition of the oil-rich coal seam enters the production well; it is transmitted to the comprehensive separation of oil and gas through the oil and gas collection pipeline The device obtains the decomposed product of the oil-rich coal seam. The invention improves the efficiency of the heating system, enhances the environmental adaptability of the underground heating device and the controllability of the heating temperature of the oil-rich coal seam. |
