| 中文摘要:干热岩（HDR）是一种可再生绿色清洁能源，其勘探开发具有埋藏深，地层破碎，压力异常，井温梯度高，孔底温度高（通常大于200 ℃）等特点，在钻井过程中易出现钻井液漏失量大，孔壁失稳掉块卡钻等问题。本文通过分析干热岩耐高温钻井液关键技术难点：处理剂及体系抗温问题、起泡问题、漏失、井壁失稳等问题。同时通过对国内外目前干热岩用耐高温钻井液体系进展及应用情况介绍，开展干热岩钻探耐高温钻井液技术发展方向研究，以期对推动我国干热岩资源勘探开发提供有效的技术支撑。 |

| Abstract:Hot dry rock (HDR) is a renewable green clean energy source; however its exploration and development is characterized with great burial depth, broken strata, abnormal pressure, high temperature gradient, high temperature at the bottom of the hole (usually＞200℃), and there are many problems during drilling, such as circulation loss, unstable wellbore, falling stones, pipe sticking. This paper analyzes the key technical difficulties on high temperature drilling fluids: temperature resistance of agents and systems, foaming, circulation loss, wellbore stability etc. At the same time, with introduction of the development and Application of high temperature drilling fluids in domestic and foreign countries, research is conducted on the development trend of the high temperature drilling fluids so as to provide effective technical support to promote the exploration and development of dry hot rock resources in China. |
