摘　　要：介绍了美国芬顿山和法国苏茨深部干热岩的典型钻井技术方案,并根据我国干热岩钻井基础和地质成藏条件,从钻井深度、井身结构、钻进工艺和钻机设备等方面制定了3种不同的干热岩钻井技术方案,给出了具体技术指标数值。通过计算,对每种方案进行了技术经济评价,结果认为:大直径钻井方案是技术可靠、经济可行的5 000 m干热岩钻探施工方案。This paper mainly introduces the deep hot dry rock drilling projects in Fenton Hill of the USA and Soultz of France,which provides some reference for the design of the deep hot dry rock drilling project.According to Chinese dry rock drilling foundation and geological reservoir formation conditions,the author established three kinds of hot dry rock drilling projects on the basis of drilling depth,well structure,drilling technology and drilling equipment,and gave the explicit value of the drilling technical indexes.The technical and economic evaluation of each project was acquired through calculation.The result shows that the large diameter drilling project is technically reliable and economically viable for the 5 000 meters hot dry rock drilling project.
