通常处理卡钻的事故是用扩孔、强力起拔或者重新钻孔的方法。几年来顿涅茨工业大学地质勘探技术和工艺教研室和《伏罗希洛夫格勒地质》托拉斯一起研制了液压推动器的标准系列。插图是振动器原理图,当振动器联接好打捞工具后,下放到孔内与钻具或套管被卡部分的上端对头接合。在开始的状态时,锤头在自重的作用下进入下部位置:进水阀闭着,而排水阀开着。液体经过异径接头和通道a进入液压缸下腔。在冲洗液的压力作用下,活塞与锤头向上升起。随着活塞—锤头的上升,弹簧压紧及依靠活门上液体的压力抑制了活门块。在上部位置时,活塞沿排水阀冲击,因而
The usual handling of stuck pipe accidents is the method of reaming, strong pulling or re-drilling. In recent years, Donetsk Institute of Geological Exploration Technology and Technology and the “Voroshilovgrad Geology” together developed a standard series of hydraulic actuators. The illustration is a schematic diagram of the vibrator. When the vibrator is connected to the salvage tool, it is lowered into the hole and engaged with the upper end of the stuck portion of the drilling tool or casing. In the beginning of the state, the hammer under the weight of the role into the lower position: inlet valve closed, and the drain valve open. Liquid through the reducer and channel a into the lower chamber. Under the pressure of the flushing fluid, the piston and the hammer head rise upwards. As the piston-hammer rises, the spring compresses and rests against the pressure of the liquid on the valve inhibiting the valve block. In the upper position, the piston impacts along the drain valve, thus
