反井钻机及石油钻机稳定器防偏机理与加工工艺研究

Research on Preventing Teflection Mechanism and a Machining Technique in Stabilizer of Raising Drill and Oil-drill

介绍了反井钻机及石油钻机的钻具稳定器(装置)在钻机施工中的作用和防偏机理,以及稳定器的常规加工工艺,并推荐了一种新加工工艺方法。着重探讨了在钻具稳定装置上堆焊碳化钨或其它耐磨合金后外表面的加工工艺性。

The function in construction and preventing deflection mechanism of the drilling tools stabilizer of raising drill or oil-drill are introduced.A sort of new maching technique is recommended.The machining manufacturability of the outside surface is especially dis cussed,the surface is welded with tungsten carbide alloy or other abrasion-resistant alloy uhen the steadying equipments of drilling tools is repaired.
