摘要： A method and apparatus for milling and/or broaching within a wellbore. A flexible broach runs into the wellbore and is located adjacent a portion of the wellbore to be broached. The broach reciprocates axially within the wellbore and removes at least part of the portion to be broached. Weight may be coupled to the broach, thereby applying a resultant side load for broaching an offset portion of the wellbore. The broach comprises a flexible member that may be a bare cable. When an abrasive material is disposed on an outer surface of the flexible member, the flexible member may be a cable, a continuous rod, or pressurized coiled tubing. Alternatively, sleeves positioned on the flexible member may have an abrasive material on their outer surface. A rotational mill that is either coupled to the broach or run in separately from the broach can further mill the wellbore.
摘要翻译：用于在井筒内研磨和/或拉削的方法和装置。灵活的拉刀进入井眼，并且位于待拉削的井眼的一部分附近。拉床在井眼内轴向往复运动，并移除待拉削部分的至少一部分。重量可以联接到拉刀，由此施加所得的侧向载荷以拉削井筒的偏移部分。拉刀包括可以是裸缆的柔性构件。当研磨材料设置在柔性构件的外表面上时，柔性构件可以是电缆，连续杆或加压的盘管。或者，位于柔性构件上的套筒可以在其外表面上具有研磨材料。与拉刀连接或与拉刀分开运行的旋转磨机可以进一步研磨井眼。
