详细介绍
HNG型恒扭矩推进器是一种新型的井下减振增扭工具,通过螺旋传动副连接,将纵向震动传递给阻尼弹簧元件,并通过碟簧和硅油两种阻尼弹簧元件来吸收钻具的纵向震动,由于内置了螺旋副,当钻头跳离井底时,螺旋副推动心轴伸出,从而补偿扭矩,提高机械钻速。该产品具有变刚度特性,在一个工作行程内存在两种刚度,及初始的低刚度和后续的高刚度,可以充分的适应不同地层的需要,给钻柱与钻头更好的保护。
Model HNG Anti Stick Slip Tool is a new type of downhole friction and drag reduction tool, which transmits circumferential and longitudinal vibration to damping spring element through sliding connection of spiral drive assembly. The HNG Anti Stick Slip Tool absorbs circumferential and longitudinal vibrations of the drill through two damping spring elements: the compressed energy storage of the disc spring and the silicon oil. The product has the advantages of good maintainability, high load resistance and high service life.
