井筒钻进井筒钻进shaft drilling {Ingtong zuonj旧井筒钻进(shaft drilling)用竖井钻井法掘进时，利用钻井设备钻凿竖井井筒的作业。井筒钻进、洗井和支护是竖井钻井法掘进的三大工序，其中井筒钻进是主体工序。它包括钻井准备工作、钻凿、防偏和测斜、故障处理等，所用时间占总工期的80%一85%。 准备工作在此期间应完成的工作有:平整井场，保证水、电管线及道路和通讯的畅通，钻凿井筒的检查孔，建立工业和生活福利设施，检查并安装钻井设备，制备洗井泥浆，进行综合试运转等。准备工作所需时间取决于钻井工程的规模、设备大小、施工组织的合理程度。 钻凿主要工作有:下钻、起钻、接长钻杆和钻进。下钻包括下钻头、钻头就位、接钻杆、下放钻杆钻头、接风管和混合器、接主动钻杆等工作。起钻按下钻相反的顺序进行。当主动钻杆钻到最低位置时，需接一根钻杆(又称加尺)，这时要停止钻进和停止泥浆循环，把主动钻杆提出转盘，并提出风管，接长一根钻杆，重新安上风管和主动钻杆，继续钻进，依此循环不已，直至钻完整个井筒。钻进时要根据地质条件正确选择合理钻进参数，注意观察转盘、钻具运转和排碴等情况。 防偏和测斜采用钻井法掘进井筒时，对井筒偏斜率有严格要求:当钻井深度小于30om时，允许偏斜率不得超过0.1%;钻深为300~4O0m时不得超过32omm，401一SOom时不得超过400mm，501~6oom时不得超过48Omm。因此在钻进过程中必须注意防止偏斜过大。井筒偏斜的原因很多，主要有钻井设备安装不当、钻压过大、冲击层中有卵石、工作面岩层软硬不均等。针对上述原因要采取相应的有效防偏措施，及时测量井筒偏斜率。当偏斜率超过允许值时，要及时纠偏。中国矿山常用的钻井测井仪有CJ一501型，CSX-731型和超声波式等。这类测井仪的测量范围是，井筒直径小于10m，井筒深度小于50om，测量精度为l%。测井仪所适应的泥浆，其粘度要小于25Pa·s，密度小于1·39/em3，温度在10一35℃。 故障处理钻井时常见的故障有泥包钻头，跳钻，卡钻，掉钻头、刀具和风管等，井筒片帮或坍塌。一旦出现这些故障，要采取相应的措施予以处理。 (何修仁)
