摘要

摘要:
利用枯竭油气藏储存热能并封存CO₂, 既可解决太阳能跨季节储热难题, 又可扩大可再生能源供暖占比, 同时还可提高CO₂地质封存的经济性。提出了枯竭油气藏储热供暖耦合CO₂封存的新方案, 以CO₂作为循环工质, 夏季吸收太阳热量储存于油气藏背斜构造中, 而冬季取出供暖, 建立了储释能过程的数学模型, 重点分析了枯竭油气藏储能系统热工性能和CO₂封存性能。结果表明: (1)新方案储能系统热工性能优异。单井平均采热功率4 808.95 kW, 每个采暖季可有效利用的平均储热量49 859.21 GJ, 平均能量储存密度28 984.23 kJ/m³。(2)CO₂密度对温度敏感的特性降低了热损失, 提高了系统效率。枯竭油气藏储能系统平均能量回收效率95.84%, 平均热回收效率83.66%。(3)储能加速了CO₂溶解。储释能过程中周期性的注入和采出工作气导致气液界面反复膨胀收缩, 增加了气水接触面积, 提高了传质动力, 加速了CO₂在水中的溶解。对比储能模式和仅CO₂封存模式, CO₂溶解比例增量由0.26%上升至2.22%。枯竭油气藏储热供暖耦合CO₂封存新方案既有优异的热工性能, 又加速了CO₂的地质封存, 是一种高值化的枯竭油气藏利用和可再生能源供暖方案, 具有大规模推广应用的潜力。

Abstract: Objective
Thermal energy storage and CO₂ sequestration in depleted oil and gas reservoirs can not only solve the problem of seasonal solar thermal energy storage but also increase the share of renewable energy space heating and enhance the economy of CO₂ geological sequestration.
Methods
A novel scheme of thermal energy storage for space heating and CO₂ sequestration in depleted oil and gas reservoirs is proposed by storing solar thermal energy in depleted oil and gas reservoirs in summer and extracting thermal energy for space heating in winter using CO₂ as the working medium. A mathematical model of the energy storage and release process is established, and the thermal performance and CO₂ sequestration performance of energy storage system in depleted oil and gas reservoirs are analysed.
Results
The results show that (1) the novel scheme has excellent thermal performance, with a single-well thermal extraction power of 4 808.95 kW, a thermal energy storage capacity of 49 859.21 GJ per heating season and an energy storage density of 28 984.23 kJ/m³. (2) The novel scheme has an energy recovery efficiency of 95.84% and a thermal recovery efficiency of 83.66% due to the strong sensitivity of the CO₂ density to temperature. (3) The solubility trapping of CO₂ in formation water is accelerated by the energy storage process. The periodic injection and extraction of CO₂ during the process of energy storage and release causes the repeated expansion and contraction of the gas-water interface, which increases the gas-water contact area and improves the driving force of mass transfer, thus leading to an increase in CO₂ dissolution in the formation water. Compared with the CO₂ sequestration model alone, the mass ratio of CO₂ dissolution in formation water for the energy storage model increases from 0.26% to 2.22%.
Conclusion
Overall, the novel scheme has excellent thermal performance. It accelerates CO₂ geological sequestration and is a high-value scheme for depleted reservoir utilization and renewable energy space heating. It has great potential for wide application.
