摘　　要：煤矿立井钻井法凿井,井筒深、直径大,地质条件复杂,需多次扩孔,所需的泥浆量大,洗井循环时间长,泥浆参数调整困难,使得钻井效率低;采用分散泥浆体系进行临时支护,容易出现泥包钻头、膨胀缩径、泥浆稳定性差及泥浆废弃量大等问题。针对这些问题,提出了解决煤矿立井钻井泥浆技术问题的对策。即采用抑制性泥浆体系,发展低固相或无固相泥浆,选择合理的泥浆参数,引进石油处理剂和泥浆固化技术及综合利用等。石油钻井泥浆技术可为煤矿立井钻井泥浆提供技术支持,引进是非常必要的。In a mine shaft sinking with a mine shaft drilling,a deep mine shaft,large diameter of the shaft,complicated geological conditions,multi reaming required,large quantity of the drilling mud required,long flushing circulation time and difficult adjustment of the drilling mud parameters would cause a low drilling rate.A separated drilling mud system applied to the temporary support would easily have a bit balling,expansible and shrinkage,poor stability of the drilling mud,large quantity of drilling mud abandoned problem and others.According to these problems,countermeasures to solve drilling mud technical problems of the mine shaft drilling were provided.The countermeasure would be a restrained mud system applied,development of a low solid phase or no solid phase drilling mud,rational selection of the drilling mud parameters,introduction of the drilling mud additive from the petroleum industry and mud consolidation technology as well as the comprehensive utilization and others.The drilling mud technology from the petroleum industry could be a technical support of the mine shaft drilling mud and the introduction would be very necessary.
