摘要
对煤田绳索取芯金刚石钻进中的钻杆结泥皮技术问题、钻孔漏失、绳钻钻头钻速低及寿命不高等技术难题进行了分析研究,并提出了具体的措施,从而使绳索取芯金刚石钻进工艺更上一个新台阶。
The technique puzzles such as drill pipe rolling mud technique problem, drilling leakage, low drill speed and short life of rope drilling bit in coalfield rope coring diamond drilling were analyzed and studied, and the concrete measurements were provided, so as to make the rope coting diamond drilling reach a new level.
