中文摘要:为了提高干热岩钻井效率和减少井内事故,在青海共和盆地干热岩GR1井进行了螺杆钻进工艺的应用。根据现场高温井况下螺杆钻具的工作特性,改进优选了螺杆钻具的耐高温橡胶和转子定子的配合间隙,并在深孔高温(孔深3705 m,孔底温度236 ℃)中首次成功尝试,为进一步改进螺杆钻具在高温井况下的应用提供了经验。

Application of PDM drilling technology in Well-GR1 drilling in hot dry rock
Abstract:This paper introduces the application of composite drilling technology of rotary (top drive) drilling and PDM drilling in hot dry rock Well-GR1 in Gonghe Basin, Qinghai so as to improve hot dry rock drilling efficiency and reduce downhole incidents. According to the working characteristics of the PDM drill under high downhole temperature, optimization was conducted of the high temperature resistance rubber, as well as the clearance between the stator and rotor of the PDM drill. It was tested for drilling of the high temperature hot dry rock well (hole depth of 3705m, hole bottom temperature 236℃) for the first time and was successful. It can provide experience for hot dry rock drilling and deep geothermal resource exploration.
