非旋转降扭稳定器(石油设备)
非旋转降扭稳定器是由两个部件组成,一是芯轴,另一个是套筒,套筒与芯轴之间可做相对转动。为提高使用寿命,在套筒内壁与芯轴的外径表面采用特殊的防磨处理。该稳定器除具有常规稳定器的功能外,由于套筒与芯轴之间的相对旋转作用,可起到降低扭矩的作用,使钻柱组合在作业中减少钻井扭矩。msn:xiaoyouloveyouhotmail.comnon-rotary stabilizers is composed of two parts, one is mandrel, another is sleeve. between the sleeve and manderl ca be relative rotation. to improve useful time, the innera wall of sleeve and the surfce fo mandrel OD were treated to use specila anti-wear. in addition to this stabilizers jave the function of general stabilzers, asthe sleeve and mandrel can bi relative rotaion, can play a role in reducing the torque, to make dril assemblye reduce torque resistance during work.
