Security Division/Dresser Industries公司研制出一种用于PDC钻头的自稳式切削结构,这种结构能促使钻头的旋转中心始终保持在钻头的结构中心位置上。 众所周知,钻头切削结构即使只承受2％的不平衡力也能引起钻头回旋。因此, Security Division / Dresser Industries has developed a self-acting cutting structure for PDC bits that enables the center of rotation of the bit to remain centered on the structure of the bit. It is well-known that bit cutting structures can cause bit rotation even with only 2% unbalanced forces. therefore,
