Problems solved by technology
However, the current gas-electric dual-purpose heating furnace has no heat storage function, and it may be switched to the electric heating mode at any time of the day. Peak filling and valley filling will contribute to the balance of the power grid, and will also increase the transportation cost of heavy oil wells and increase production costs

The invention discloses a crude oil conveying pipeline regenerative heater. Heat water in a heater body is heated during the trough period of electricity consumption by setting the turn-on time of anelectric heater to be between 22:00-8:00, and the temperature of the heat water in the heater body is enabled to reach a setting temperature for heat storage. The electric heater is in a stop period during the electricity consumption peak during the period of 8:00-22:00, and the heated heat water releases heat to heat crude oil flowing through a coil pipe during the period. During the high temperature period of the heat water, a part of unheated crude oil is diverted by adjusting the opening degree of a diversion regulating valve to enable the temperature of mixed liquid after the heated crudeoil and the unheated crude oil meet at the communication point of a regulating pipe and an oil discharging pipe to reach the temperature of viscosity reduction for smooth delivery. Therefore, the electric heater in the crude oil conveying pipeline regenerative heater can achieve the purpose of heating and viscosity-reducing transportation of heavy oil in an oil field by only working in the off-peak period of electricity consumption during 22:00-8:00, and can contribute to the peak load shifting and power grid balancing, the transportation cost of heavy oil wells can be reduced, the productioncost is saved, and significant economic and social benefits are achieved.
Description
technical field [0001] The invention relates to a device for heating and reducing the viscosity of heavy oil in an oil field, which is a heating furnace for heating and reducing the viscosity of the heavy oil well in the oil field, in particular to a heat storage heating furnace for a crude oil transportation pipeline. Background technique [0002] When the heavy oil extracted from the oil field is to be transported, it is necessary to heat the heavy oil in the pipeline to reduce the viscosity and increase the oil mobility to achieve smooth transportation. At present, the way to heat the heavy oil in the pipeline at the wellhead is to install a heating furnace at the wellhead, and use the natural gas separated from the casing in the well as the heat source. Since the natural gas in most wells is insufficient, some wellhead heating furnaces use Gas-electric dual-purpose heating furnace, if the amount of natural gas is insufficient, switch to electric heating, so as to ensure ...
