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 re-quired ,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 easi-ly have a bit balling ,expansible and shrinkage ,poor stability of the drilling mud ,large quantity of drill-ing mud abandoned problem and others.According to these problems ,countermeasures to solve drill-ing 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 ,ration-al selection of the drilling mud parameters ,introduction of the drilling mud additive from the petrole-um 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.
