摘要： Retrieving a down hole tool at a lower end of a string of casing can be performed with drill pipe during a casing-while-drilling operation. The operator suspends the casing in the well from a drilling rig floor opening. A string drill pipe is lowered into the casing while the casing is suspended for engaging and retrieving the down hole tool. When circulation is desired, the operator secures a circulation tool to an upper end of the drill pipe, then lowers the drill pipe and the circulation tool to close off an upper end of an inner annulus between the drill pipe and the casing. The operator circulates fluid down the circulation tool and the drill pipe and back up an outer annulus surrounding the casing. The connection between the circulation tool and the casing allows the operator to reciprocate the casing.

摘要： A liner drilling system employs a bottom hole assembly that may be retrieved before reaching the total liner depth. The system includes an outer string made up of a liner and a profile nipple. An inner string including a running tool, drill pipe, and a drill lock tool are lowered into the outer string and rotationally and axially locked to the outer string. Drilling may be performed by rotating the inner string, which also rotates the outer string. The operator may retrieve the inner string by pulling the inner string and the liner upward until the upper end of the liner is located at the drilling rig floor. While supporting the liner at the drilling rig floor, the operator retrieves the inner string, then re-runs it back into the outer string.

摘要： A method of drilling a well and installing a liner includes assembling concentric inner and outer strings of tubulars, A drill bit is located at the lower end of the inner string and a liner with a liner hanger makes up part of the outer string. The inner and outer strings may be rotated in unison to drill the well. At a selected depth, the operator sets the liner hanger and retrieves the inner string. The operator lowers a packer and a cement retainer on a string of conduit. The packer engages the liner hanger and the cement retainer is conveyed to the lower end of the liner. The cement retainer prevents cement in the outer annulus from flowing back up the string of conduit. The operator manipulates the conduit to set the packer.
摘要翻译：钻孔和安装衬套的方法包括组装同心的内管和管柱，钻头位于内柱的下端，具有衬套的衬套构成外柱的一部分。可以一致地旋转内弦和外弦以钻井。在选定的深度，操作员设置衬管悬挂器并检索内部字符串。操作员将一个封隔器和一个水泥固定器放在一排导管上。封隔器接合衬套，水泥保持架被输送到衬套的下端。水泥保持架可以防止外环中的水泥从管道中流回。操作者操作导管以设置封隔器。

摘要： An installation system for installing a liner in a well includes drilling while simultaneously running the liner. A string of drill pipe with a bottom hole assembly including a drill bit on a lower end is lowered into the liner while the liner is suspended at the rig floor. The bottom hole assembly engages a lower sub of the liner for torque transmission. A running tool secured to the drill pipe engages the upper sub such that the running tool supports the weight of the liner and transmits torque. The drill pipe and liner are rotated to drill deeper into the wellbore. The liner hanger can be set to engage the casing, then released and reset at a different point.
