摘要： A method of cutting a control line mounted on an outer surface of a downhole tubular that includes providing a cutting tool having a main body, and a cutting head on a lower end of the body that rotates with respect to the body. A cutting blade is on a lower end of the cutting head, which is rotatable by a motor, where the blade is selectively pivoted radially- outward from an axis of the cutting head. As the cutting head rotates, the cutting blade orbits within the tubular axially offset from the axis. When the tool is inserted into the tubular, the radial offset of the blade is controlled so it pivots radially outward into contact with the tubular when the blade approaches an azimuthal area proximate the control line. The cutting blade is retracted when its orbit moves it past the azimuthal area proximate the control line.
摘要翻译：一种切割安装在井下管的外表面上的控制线的方法，该控制线包括提供具有主体的切削工具，以及在主体的相对于主体旋转的下端上的切割头。切割刀片位于切割头的下端，其可由电动机旋转，其中刀片选择性地从切割头的轴线向外径向地枢转。当切割头旋转时，切割刀片在与轴线轴向偏移的管状物内轨道运动。当工具插入到管状件中时，叶片的径向偏移被控制，使得当叶片接近控制线附近的方位区域时，其径向向外枢转地与管状物接触。当其轨道将其移动通过靠近控制线的方位角区域时，切割刀片缩回。

摘要： An anchoring system for use with a downhole tool includes a body with anchor members mounted on the body that pivot radially outward from the body and into engagement with an inner surface of a tubular. Curved slots are provided along a portion of the members and a sliding block has a protrusion that projects into the slots. The slots are curved so that when the block is urged axially within the body, the interaction between the slots and protrusions pivots the members radially outward. A piston is urged through the body to drive the block. Optionally, an elongate helical gear may cooperate with grooves formed in an edge of the members so that rotating the gear pivots the members radially outward.

摘要： A method for controlling the electrical power delivered to a downhole system. The downhole system may include a power supply, a downhole tool, and a wire or cable connecting the downhole tool to the power supply. A resistive load, such as a motor, is included with the downhole tool. The power supplied to the downhole tool is dynamically adjustable to match the resistive load voltage and power rating. Dynamically adjusting power is accomplished by varying voltage from the power supply, varying the resistive load requirements, or a combination of both.
