我队在小口径金刚石钻进中,烧钻事故很多。其原因有: 1.缺乏严细作风。主要表现在钻进中不注意观察仪表、回水,不注意听柴油机运转声,不检查钻具通水情况,不重视钻杆接头密封。 2.冲洗液循环不正常。因活塞螺帽松开造成水泵单缸来水,使水量水压不稳定;钻杆接头通水孔、双管通水孔被杂物堵塞;三通不灵、高压管路严重漏失使孔底水量
My team drilling in small caliber diamond burned a lot of accidents. The reasons are: 1. Lack of strict style. Mainly in the drilling did not pay attention to the observation instrument, back to the water, do not listen to listen to the sound of diesel engine, drill does not check the water situation, do not attach importance to drill pipe joints sealed. 2 rinse liquid circulation is not normal. Due to the loosening of the piston nut, the single pump of the water pump causes the water pressure to be unstable. The drill pipe joint passes the water hole and the double pipe water hole is blocked by debris. Water volume
