摘要
即使用绳索取心钻具钻深孔,在易跑斜地层中仍会造成孔斜.本文从金刚石钻头选型、钻具组合、冲洗液种类的确定和钻进工艺方法等方面,提出了防斜措施.
When drilling in hard formations, even if the wire-line coring tool is used, hole deflection problem could be Stile occasionally happened. Some preventive measures against hole deflection are suggested in this paper by taking following factors into consideration: (1) diamond bit type selection;(2)the combination of drilling tools; (3) making choice of suitable flush-fluid; (4) reasonable drilling technology.
