Problems solved by technology

[0003] Thermal oil recovery equipment includes a steam generator for generating high-temperature steam. The existing steam generators heat water by burning coal, oil or natural gas to obtain the required high-temperature steam, but the high-temperature steam is obtained through the heat energy of combustion. Water vapor, in addition to consuming a large amount of non-renewable resources, will also cause environmental pollution, which is contrary to the energy conservation and emission reduction advocated by the state

Abstract

The invention provides an oil recovery system utilizing light thermal energy. The oil recovery system comprises a light thermal steam generation system and a thermal oil recovery device, wherein the light thermal steam generation system is used for generating steam by making use of thermal energy of sunlight and injecting the steam into an oil reservoir, and the thermal oil recovery device is used for collecting oil, heated by steam and diluted, in the oil reservoir. By the oil recover system utilizing the light thermal energy, energy conservation and emission reduction can be realized, utilization rate of solar energy is increased, and cost of oil exploitation is lowered.

Description

technical field [0001] The invention relates to the field of thermal oil recovery, in particular to an oil recovery system utilizing light and heat energy. Background technique [0002] Heavy oil is crude oil with high asphaltene and colloid content and high viscosity. Due to its special characteristics, heavy oil is a kind of crude oil that is difficult to extract and has high extraction cost. At present, the commonly used heavy oil recovery technology in the world is thermal oil recovery technology. This technology is to inject high temperature water vapor into the oil reservoir. Water vapor will greatly reduce the viscosity of heavy oil, improve the fluidity of heavy oil, and increase the production efficiency. The high heat of high-temperature water vapor will also expand the heavy oil, increasing the power of heavy oil discharge from the reservoir. [0003] Thermal oil recovery equipment includes a steam generator for generating high-temperature steam. The existing ...
