Publish Date: 10 October 2014

摘要: 夏日哈木矿区地层复杂,在青海祁漫塔格重点成矿带具有一定的代表性。该矿区地层呈脆性,坚硬并且破碎,部分钻孔钻进过程中存在钻头寿命低、钻进效率低、孔内事故多等问题。针对该矿区地层特点及钻进难点,在总结以往工作经验基础上,对钻头选型及参数选取、钻机选择及时效分析、钻具振动及处理、钻井护壁及堵漏、钻孔结构设计及施工等方面进行分析并提出综合应对技术措施。

Abstract: The strata are brittle, hard and fragile in Xiarihamu mining area, which has certain representativeness in Qiman-tage key metallogenic belt of Qinghai.Many problems such as short bit life, low drilling efficiency and hole accidents often occur in the drilling process.According to the strata characteristics and drilling difficulties and based on the summary of drilling experience, analysis is made on bit and parameter selection, drilling rig selection and efficiency analysis, drilling tool vibration and dispose, hole wall protection and plugging and hole structure design and construction, comprehensive technical measures are also put forward.
