摘要： A method for milling an opening, slot, hole, or window in a tubular of a tubular string in a wellbore, has been invented which includes installing a mill system in the tubular at a desired milling location, and milling an opening in the tubular. In one aspect the method includes using a mill which has a weight member below the mill, above the mill, or both. In one aspect additional weight is added to the weight member once it has been introduced into the tubular string.

摘要： A method is provided that allows the operator to re-enter a primary wellbore from a lateral wellbore after the lateral wellbore has been completed. The method generally comprises the steps of locating a cutting device such as a milling bit adjacent a tubular such as a liner within a wellbore, rotating the milling bit while maintaining an axial position of the milling bit relative to the liner to initiate an opening, and rotating and axially advancing the milling bit to complete the opening. In addition, a bottom hole assembly that facilitates re-entry into the primary wellbore from a lateral wellbore is provided. The bottom hole assembly generally includes a drill collar or other heavy pipe structure, and a mill. The mill has a body and cutting structures. The cutting structures apply lateral force against a surrounding pipe to form an initial lip through the wall of the pipe.
摘要翻译：提供了一种方法，其允许操作者在侧面井眼完成之后从侧井眼再次进入主井眼。该方法通常包括以下步骤：将诸如铣头之类的切削装置定位在井筒内的诸如衬管之类的管状物上，使研磨钻头旋转，同时保持铣头相对于衬套的轴向位置以启动开口;以及旋转并轴向推进研磨钻头以完成开口。另外，提供了一种便于从侧井眼再次进入主井眼的底孔组件。底孔组件通常包括钻铤或其他重的管道结构以及碾磨机。磨机有一个身体和切割结构。切割结构对周围的管施加横向力，以通过管的壁形成初始的唇。
