在深井钻进中,蹩跳钻现象是经常发生的,严重时使操作者无法加压而得不到进尺。为钻达目的层,就得不惜工本,经常起钻换钻头。钻具减震器是征服蹩跳钻的有效工具。70年代从美国引进,但成本较高。近年来,在引进的基础上,自己制造了成本较低的复合蝶簧钻具减震器(见图)。 In deep well drilling, the phenomenon of bored and jumped frequently occurs, so serious that the operator can not pressurize without gaining footage. To drill up to the target layer, you have to spare no effort, often starting to drill bit. Drill Shock Absorber is an effective tool to conquer a broken jumper. Introduced from the United States in the 1970s, but at a higher cost. In recent years, on the basis of its introduction, it has made its own low-cost composite butterfly spring drill shock absorber (see photo).
