中文摘要:
      超临界CO2强化深层卤水开采可显著地提高卤水的开采效率,同时增强CO2的封存安全也是一种实现卤水高效开发和减缓温室效应的双赢选择.本文通过数值模拟的方法对比研究了不同井群布设方法下超临界CO2强化深层卤水开采的效果,得到的结论如下:无论是矩形井网法还是三角形井网法,超临界CO2强化深层卤水开采的效果都是非常显著的.基于提出的4种布井方法,从卤水开采总量、卤水越流风险、CO2注入总量、CO2泄漏比和区域压力调控这几个方面对比分析:7B6C与9B4C相当、6B7C次之、4B9C效果略差,整体上集中式的三角形井网法略优于矩形井网法,但这两种布井方法没有明显的优势差别.因此,在实际的超临界CO2强化卤水开采项目中,可根据现场地形和工程条件选择比较合适的布井方法.
英文摘要:
      Deep brine recovery enhanced by supercritical CO2 is a win-win choice for the efficient development of brine and the mitigation of greenhouse effect since it can not only significantly improve brine production efficiency but also enhance the safety of CO2 sequestration.In the present work,numerical simulation was carried out to investigate the effect of well pattern arrangement for the deep brine recovery enhanced by supercritical CO2.Numerical simulation results show that whether in the rectangle well pattern or in the triangle well pattern,both of the efficiencies for the deep brine recovery enhanced by supercritical CO2 are significant.For the four well pattern arrangements proposed in this paper,the schemes of 7B6C and 9B4C act best in brine production yield,brine recharge risk,CO2 injection amount,CO2 leakage ratio and the regional pressure control,followed by 6B7C,with 4B9C last,there is no obvious advantage of the both well pattern arrangements.Therefore,it is flexible to choose the well pattern according to the site shape and the project condition for the actual project of deep brine recovery enhanced by supercritical CO2.
