摘要： A cutting tool (22) includes a plurality of pivoted blades (36) for swinging outwardly to an expanded radial position for first cutting the walls of multiple casing strings (10, 11), and then removing a predetermined length of the casing strings (10, 11) simultaneously in a cutting action. Pivoted blades (36) have cutting elements (66) of a similar size and shape positioned about upper, lower sides (62) of the blades (36) engage the upper annular cut ends of the casing strings (10, 11) in a cutting action without tripping or removal from the bore hole.

摘要： A tool for cutting or milling casing in a well is disclosed. It includes a plurality of blades extending outwardly to a substantially radial position for cutting the walls of casing strings and removing a predetermined length of the casing strings in a cutting action. The blades have cutting elements positioned on leading faces of the blades to engage the casing strings in a cutting action without tripping or removal from the bore hole. The cutting elements can be arranged in rows and columns. The cutting elements can be shaped to continually present a sharp cutting edge to the object being milled. The cutting elements can be inclined at a negative axial rake angle to cause the metal chips cut from the object being milled to break off at short lengths. The cutting element can also have surface irregularities to cause the metal chips cut from the casings to break off at short lengths. The cutting element can also have stress relieving grooves to prevent the propagation of a crack across the face of the element.
摘要翻译：公开了一种用于在井中切割或铣削套管的工具。它包括多个叶片，其向外延伸到基本上径向的位置，用于切割套管柱的壁并在切割动作中移除预定长度的套管柱。叶片具有定位在叶片的前表面上的切割元件，以切割动作使套管柱接合，而不会从钻孔中脱落或移除。切割元件可以排列成行和列。切割元件可以被成形为连续地向被研磨的物体呈现锋利的切割边缘。切割元件可以以负轴向前角倾斜以使得从被研磨的物体切割的金属屑以短的长度断裂。切割元件还可以具有表面不规则性，以使得从壳体切割的金属屑以短长度断开。切割元件还可以具有减轻应力的凹槽，以防止裂纹在元件的表面上传播。
