【摘要】 连续管侧钻定向井技术在中国刚刚起步,在工艺、装备与工具等相关技术方面缺乏足够认识。为此,介绍了国外连续管侧钻定向井技术现状与最新的进展,以及国内开展的连续管侧钻定向井现状与存在的难点,通过结合相关井次的理论分析与现场数据回归统计,得出了国内开展连续管定向钻井需要考虑的几个难点,研究分析了地面装备配套、水力学、岩屑床、钻压等方面参数,并进行了量化,为下步开展连续管定向钻井具有借鉴与指导作用。更多还原

【Abstract】 CT directional drilling has just started in China, and there is a lack of sufficient understanding in CT drilling process, equipments, tools and other related technologies. In this paper, the current situation and the latest progress of this technology abroad were introduced as well as the current situation and the difficulties of CT directional drilling in China. By combining the theoretical analysis of relevant wells and the statistics of field data regression, several difficult problems were put forward. The parameters of ground equipment matching, hydraulics, cuttings bed and bit weight were analyzed and quantified. The result can be used as reference and guidance in the next CT drilling.更多还原
