Abstract

Provided is a solid heat storage electric-boiler two-stage heat-exchange oil-field steam-injection boiler heating system, comprising a heat-source heating system, a steam injection system, and a discharge pipe, said heat-source heating system comprising said solid heat storage electric-boiler and two-stage heat exchange system. Using the solid heat storage electric-boiler two-stage heat exchange system, it is possible to generate subcritical and supercritical steam; said steam is injected into underground heating crude oil by means of a steam injection process system, thus heating a heavy-oil oil well by steam injection. The heating system may also use low-price nighttime electricity from the grid at low troughs so as to convert nighttime electrical energy to heat energy and perform high-temperature heat storage by means of the solid heat storage electric boiler. The high-parameter steam produced by the heating system heats the heavy-oil oil well by steam injection; not only does the invention solve the problem of oil-field steam injection boiler combustion and emissions pollution, but an electric boiler and energy storage technology can be combined to perform peak-trough difference adjustment on an electrical grid.

Description

technical field [0001] The invention relates to the field of steam injection production in heavy oil oilfields, in particular to equipment for generating heating steam in oil production plants and oil wells and improvement of steam injection systems. Background technique [0002] As oil resources gradually enter the fields of human life and social interaction, global oil consumption is increasing rapidly, thin oil resources are decreasing day by day, and oil prices are rising. People are turning their attention to the development of abundant heavy oil resources. Thermal recovery steam injection boiler, as the key core equipment of heavy oil recovery technology, is widely used in major oil fields at home and abroad. The exploitation of heavy oil wells requires a special steam injection boiler, that is, to use the high-pressure and high-temperature steam generated by the steam boiler to inject the high-temperature and high-pressure steam into the underground of the oil well to...
