随着廉价化石燃料和其他已知燃料的可用性逐渐减少，热干岩（HDR）技术开始于帮助满足未来能源需求的想法。人类发展报告的概念本身非常简单，但相关技术的开发所花的时间比预期的要长得多。任何一个对岩石等自然材料有经验的人都知道，总有一些无法估量的东西没有被真正理解，而且目前确实不能以一种完全令人满意的方式来处理。此外，地质学总是有一种向我们提出新问题的习惯。在这些支持下，并考虑到所提供的资金有限，令人鼓舞的是，在漫长的不确定性隧道的尽头终于看到了光明。1997年在苏茨苏福雷（法国）进行的循环试验的结果显然表明，我们可能已经提出了一种类型的概念和一组适当的背景场地条件来推进技术。HDR储层的概念已经从石油工业中借用的单个便士形裂缝发展到现在的地堑或HWR（热湿岩）概念。到目前为止，国际合作一直是一个关键问题，而这项研究的昂贵性质要求这种类型的合作在未来继续开辟新天地。必要的支持技术也在发展，利用这一令人兴奋的新发展的时机似乎已经成熟。不是所有的答案都是已知的，但至少我们现在知道该问哪些问题。值得记住的是，目前还没有商业化的HDR工厂，可以为规划一个新的单位提供有关建筑、运营和维护成本的真实的数据。这不应被视为一个无法克服的问题。如果是这样的话，那么我们就不会有飞机、钢铁、航运、电信或核工业了。许多人认为，HDR技术迟早会被需要，现在的重要问题是，当需要出现时，它能多快地付诸实践！最近在Soultz现场组建财团的举动非常令人鼓舞，并显示了商业和工业利益对其未来的承诺和信心。(C)1999 CNR。由Elsevier Science Ltd.出版，版权所有。
Hot Dry Rock (HDR) technology started from an idea to help fulfill future energy needs as the availability of cheap fossil and other known fuels slowly reduces. The HDR concept itself is very simple but the development of the associated technology has taken significantly longer than anticipated. Anyone with experience of natural materials such as rocks knows that there are always imponderables that have not been really understood and indeed cannot at present be dealt with in a fully satisfactory manner. Furthermore, geology always has a habit of presenting us with new problems. Under these auspices and considering the limited funds that have been made available, it is encouraging to note that at long last light is visible at the end of the long tunnel of uncertainty. The results of the 1997 circulation test at Soultz-sous-Forets (France) certainly seem to show that we may have come up with a type of concept and an appropriate set of background site conditions to advance the technology.The concept of an HDR reservoir has evolved from that of a single penny-shaped fracture borrowed from the oil industry to the present graben or HWR (Hot Wet Rock) concept. International co-operation has been a key issue so far, and the expensive nature of this research demands that co-operation of this type continues to break new ground in the future. The necessary supporting technology has also evolved and the time appears to be ripe for taking advantage of this new and exciting development. Not all the answers are known, but at least we know now which questions to ask. It is worth remembering that there is still no commercial HDR plant in existence to provide real data on building, operating and maintenance costs for planning a new unit. This should not be regarded as an insuperable problem. If such were the case, then we would not have any aircraft, steel, shipping, telecommunication or nuclear industries.Many people fed that HDR technology will be needed sooner or later and the important question now is how quickly it can be put into practice when the need does arise! Recent moves to form a consortium for this next step at the Soultz site are very encouraging and show the promise and confidence that commercial and industrial interests have in its future.
