在处理孔内事故时常会碰到孔内钻具丝扣特别紧的情况,本人对此摸索出一些办法,比传统处理法可节省时间几倍,十几倍。主要使用反丝震击器。只要没被泥沙埋坚固,经震击没有反不动的,如能送水进去,埋得又不太坚固,则可全部震上来。一、震击器的构造及作用反丝震击器主要由外管、轴、齿盘及牙嵌等组成(如图),上下齿盘和外管以丝扣连接,上下牙嵌和半轴亦丝扣相连接。下齿盘和下牙嵌结合起来矢锥吃扣作用,上齿盘与上牙嵌结合起震击作用,外管
When dealing with accidents in the hole, I often encounter a situation where the drilling thread in the hole is particularly tight. I have developed some methods for this, which can save several times, more than ten times, compared with the traditional treatment. The main use of anti-wire jars. As long as it is not buried solid by the sand, the shock is not moving, if you can send water into it, and buried it is not very strong, you can all shock up. First, the structure and function of the jar The anti-wire jar is mainly composed of the outer tube, shaft, tooth plate and tooth insert (pictured). The upper and lower tooth plates and the outer tube are connected by threaded buckles. The upper and lower teeth are embedded and the half shaft Also connected deduction. The lower teeth plate and the lower teeth are combined to act as a cone cone, and the upper teeth plate and the upper teeth combine to act as a shock. The outer tube
