金刚石钻探施工中，钻具与孔壁间隙较小，下钻时冲洗液顺钻杆内向上喷出，造成孔口污染：遇到涌水严重地层提钻时也有发生类似情况，不仅损耗泥浆或润滑剂冲洗液，而且污染设备和场地，妨碍操作，影响安全生产。为此设计了一种防喷接头，经全队使用，效果良好。 Diamond drilling construction, drilling and hole wall clearance smaller, flushing fluid down the drill pipe when the next jet, causing the orifice pollution: serious gushing water formation encountered a similar situation when drilling, not only loss of mud or lubrication Agent rinse solution, and pollution of equipment and venues, hinder the operation, affecting safety in production. For this reason designed a spray-proof connector, the team used to good effect.
