摘　　要：水力压裂开采干热岩是目前干热岩资源开发普遍优选的方法,本文在阐述其应用现状及特点的基础上,分析了水力压裂技术应用于干热岩资源开发存在的技术问题及诸多不确定因素。提出了注入井水平对接与压裂组合开采方案以及注采井水平对接开采方案,分析了两种方案涉及的技术可行性。Hydraulic fracturing to exploit hot dry rock resources is the preferred method at present,based on its application status and characteristics,this paper analyzes the technical problems and many uncertain factors in the application of hydraulic fracturing technology to development of hot dry rock resources.The combined development scheme of horizontal docking for injection well with fracturing and horizontal docking scheme of injection‑production wells are put forward,the technical feasibility of the two schemes is analyzed.
