    摘要:

    干热岩作为一种清洁和可再生能源,较传统能源有很多优点,但钻探难度大一直是制约其推广应用的主要问题。本文首先分析了干热岩高温钻探的特点和难点,随后系统地梳理了包括先进钻井技术、钻井工具及钻井液的国内外研究进展。详细评述了气体钻井、液氮射流钻井及热—机械联合钻井(CTMD)三种钻井技术的运行机理和适用范围,钻井工具的研究现状和发展方向,以及不同高温钻井液体系的选取依据和整体性能优化思路。最后,结合目前的研究水平进一步对钻进过程中钻井设备的高效优选、新型钻井液的整体性功能评价以及设备参数的动态调控进行了展望,以期为我国高温干热岩采热系统钻探研究及工程实践提供参考。

    Abstract:

    HDR(hot dry rock) is a kind of clean and renewable energy, which has many advantages over traditional energy. However, the difficulty of drilling has always been the main problem limiting its application and promotion. In this paper, the characteristics and difficulties of high-temperature drilling in the HDR are analyzed firstly , and then the domestic and foreign research trend, including advanced drilling technology, drilling tools, and drilling fluid, is systematically reviewed. The operation mechanism and application scope of gas drilling, liquid nitrogen jet drilling and combined thermal mechanical drilling (CTMD), the research status and development direction of drilling tools, the selection basis and the overall performance optimization idea of different high-temperature drilling fluid systems are commented in detail. Finally, combined with the current research level, the prospects of the high-efficiency optimization of drilling equipment, the overall function evaluation of new drilling fluid, and the dynamic control of equipment parameters in the drilling process are further discussed. It is expected to provide a reference for the drilling research and engineering practice of high-temperature hot dry rock heating system in China.
