Groove type solar high-temperature heat collecting device and method for thickened oil steam injection production through groove type solar high-temperature heat collecting device

Abstract

The invention discloses a groove type solar high-temperature heat collecting device. The groove type solar high-temperature heat collecting device comprises a paraboloid groove type heat collecting system, a heat storage system, a high-temperature and high-pressure steam generation system, an oil field sewage water treatment system and an automatic control system. The paraboloid groove type heat collecting system is used for storing collected solar energy in the heat storage system. The heat storage system supplies heat energy to the high-temperature and high-pressure steam generation system so that overheat steam can be generated. The oil field sewage water treatment system is used for generating overheat steam after heat exchange and conveying overheat steam to a producing well for cyclic utilization. The automatic control system is used for system tracking, data collecting and alarm monitoring. An alternate circulation technology improvement method is adopted, the groove type solar heat collecting device is combined with heat oil recovery methods such as steam huff and puff and steam flooding, an overall plan is made, continuous steam supply of the groove type solar device is achieved, and more crude oil is produced.

Description

technical field [0001] The invention relates to the technical field of heavy oil exploitation technology and trough solar thermal utilization, in particular to a trough solar high-temperature heat collection device used in heavy oil steam flooding, steam huff and puff and other steam injection oil production and its method for heavy oil steam injection production . Background technique [0002] Trough solar heat collection technology is a new clean energy technology that has developed rapidly in recent years and has a good development prospect. In addition to generating electricity, the trough solar thermal collection system can also provide steam required for industrial production. In the petroleum industry, for some heavy oils with high viscosity, high freezing point and poor fluidity, the steam required for heavy oil production is usually produced by burning coal, residual oil or natural gas, but this steam production method consumes a lot of energy. The pollution is hi...
