【摘要】 地热回灌是一种避免地热废水直接排放引起的热污染和化学污染的措施,并对维持热储压力,保证地热田的开采技术条件具有重要的作用。目前回灌已经成为世界范围内数十个重要的地热田生产运行中的一项日常工作,在美国、新西兰、冰岛、意大利、法国、日本、罗马尼亚、丹麦、菲律宾和萨尔瓦多等十多个国家得到了广泛的应用。在国内,北京、天津的地热回灌也已经有了良好的开端。回灌是地热田管理中最为复杂的一项技术,为了避免因回灌而引起热储冷却,需要进行回灌试验和示踪试验,并在回灌过程进行全面的监测工作。更多还原

【Abstract】 Reinjection is a kind of measurements for the disposal of waste geothermal water that may cause thermal and chemical pollution to the environment, and it is also useful in counteracting the pressure decline of geothermal reservoirs and maintaining the production conditions of geothermal fields. Reinjection has become a routine in the management of tens important geothermal fields in the world, especially in the US, New Zealand, Iceland, Italy, France, Japan, Romania, Denmark, Philippine and El Salvador. Domestically, geothermal reinjection has also started in Beijing and Tianjin. Reinjection is the most complicated technique of geothermal field management. To avoid the risks of cooling of the geothermal reservoirs caused by colder water reinjection, reinjection experiments and tracer tests should be carried out before larger scale reinjection, and a good monitoring program is essential to any reinjection projects.更多还原
