| 本文介绍了河北省唐山乐亭马头营干热岩勘探孔M-1井钻探施工概况以及采用的关键技术。通过对海水钻井液、耐高温淡水钻井液、螺杆复合钻进技术、螺杆钻具取心技术、高温困难等难点的研究，解决了海水钻井液护壁困难，高温钻井液的稳定性差、干热岩全面钻进和取心钻进效率低等难题，保证井内安全，提高钻进效率。采用抗高温双凝双密度水泥浆体系和相关针对性技术措施，保证高温环境下的固井质量。通过该地区地层的认识分析，对以后在同类地层实施干热岩钻井提供宝贵经验。马头营M-1井终孔深度为4502.11m,在3965m处发现温度为150℃的干热岩，是目前京津冀地区第一口温度大于150℃的干热岩井。 |

| This paper presents the general situation and key techniques of the drilling well M-1 in Matouying dry hot rock exploration hole, Leting, Tangshan, Hebei Province. A series of problems have been studied on the sea water drilling fluid, high temperature resistant fresh water drilling fluid, screw composite drilling technique, screw hole coring technology, and high temperature, thus solving the difficulty of sea water drilling fluid well protection, poor stability of drilling fluid under high temperature, and low efficiency in hot dry rock drilling and coring drilling to ensure the safety of the borehole and improve drilling efficiency. The high temperature resistant double condensation and double density cement slurry system and relevant technical measures are adopted to ensure the quality of cementing in the high temperature environment. Through the understanding and analysis of the strata in this area, this work provides valuable experiences for drilling in the same strata in the future. The final hole depth of the M-1 well in Matouying is 4502.11m, and hot dry rock with a temperature of 150℃ is found at 3965m, which is the first hot dry rock well with a temperature of more than 150℃ in the Beijing-Tianjin-Hebei region so far. |
