地热资源储量丰富,分布广泛,开发前景广阔.但是在现有地热钻井技术条件下进行地热开发的周期长、成本高,所以亟待钻井技术的突破使巨大的地热资源得到经济有效地开发.碎裂钻井技术是一种采用了新的钻井原理的钻井技术,其能够有效地解决常规钻井过程中经常遇到的诸如在坚硬地层中进尺慢等棘手问题,一旦得到商业化应用,将会对地热资源经济有效地开发产生革命性的影响.在分析常规钻井技术存在的问题的基础上,介绍了碎裂钻井技术的工作原理及碎岩机理,阐明了其优缺点,为该技术在地热钻井中的应用研究提供参考.

There are plenty of geothermal resources widely distributing with broad prospects for development.A new princi-ple of drilling has been introduced in spallation drilling;it can resolve the knotty problems such as slow penetration rate of-ten encountered while drilling in hard rocks.As soon as the technology is put in commercial application, it will have revolu-tionary consequences for the exploitation of geothermal resources.Based on the analysis on the problems in the traditional drilling technology, the working mechanism of spallation drilling is introduced; the advantages and disadvantages are de-scribed.It will provide references to the application of spallation drilling in geothermal development.
