Abstract: In a plug an abandon environment with casing and a tubular string running through the casing a tool is placed at a desired location for a severing of the inner tubular. A first set of blades is extended from a housing to cut radially until the inner tubular is severed. A second set of blades are then extended for axial milling with a reach limit of the outside wall of the severed tubular at a location between upsets. As the axial milling reaches an upset, the second set of blades is allowed to retract and a third set with a longer reach is extended to axially mill the upset. Thereafter the third set of blades is allowed to retract and the second set is extended to continue axial milling. The second and third sets of blades can be reversed so that initial axial milling can be at the upset rather than between the upsets followed by milling between the upsets with the shorter reach blades.

Abstract: A clamp device that attaches an umbilical to a drill string incorporates a junk basket. The basket is notched to accept the umbilical and an insert piece is slipped into the notch after the umbilical is properly in position. The insert piece straddles the umbilical and is secured the balance of the basket to complete the basket. The basket can be slipped over the drill pipe and either secured directly to the outer surface of the drill pipe or against a support member that is supported off the drill pipe. One or more of such baskets can be used and they can also function as umbilical clamps. The basket can also be vertically split to allow mounting it over the drill pipe and umbilical without having to slip it over an end of the drill pipe as the drill pipe is tripped into or out of the hole.

Abstract translation: 将脐带连接到钻柱的夹紧装置包括垃圾篮。 在脐带适当就位后，筐被切口接受脐带，插入片滑入槽口。 插入件跨越脐带并固定篮的平衡以完成篮。 篮子可以滑过钻杆，并且直接固定在钻杆的外表面上，或者固定在从钻杆支撑的支撑件上。 可以使用一个或多个这样的篮子，并且它们也可以用作脐带夹。 筐也可以垂直分开，以便当钻杆被跳入或从孔中跳出时，将其安装在钻管和脐带上，而不必将其滑过钻杆的一端。
