| 摘 要： | 陕西榆林地区煤田钻探通常使用单管钻进,钻进效率低、技术落后。针对这一现状,使用金刚石复合片钻头绳索取心技术,配合国产微电脑控制全液压钻机,取得了良好的效果。文章主要从冲洗液配方和钻进参数设计、ZK2508现场施工过程中出现问题及处理、经验分析总结等方面进行阐述,并讨论国产全液压钻机在金刚石小口径钻进的优势与不足,以期为以后的煤田钻探提供借鉴。

| Abstract: | Single-tube drilling is usually used for prospecting coal formation in the Yulin area, Shanxi Province, which is a kind of backward technique with low drilling efficiency. To solve this problem, the PDC bit wire-line core drilling technology has been employed, coupled with the microcomputer controlled all-hydraulic operated drill rig, which obtained good results. Several aspects of this technology are presented in this article, including the design of drilling fluids and drilling parameters, problems and treatments of ZK2508 during the drilling process, the summary of experiences, and the analysis of the strengths and weaknesses of all-hydraulic operated drill rig made in China based on in-site drilling. Some techniques mentioned in this article are worthy to be used for reference in drilling of coal fields. |
