摘要： An assembly for formation and completion of deviated wellbores is disclosed which includes a toolguide and a casing section which can be used together or separately. The toolguide includes a lower orienting section and a whipstock having a sloping face, commonly known as the directional portion of a whipstock. The toolguide is coated with a material such as epoxy or polyurethane to provide a repairable surface and one which can be removed to facilitate removal of the toolguide from the well bore. The lower orienting section has a latch which extends radially outwardly from the section and can be locked in the outwardly biased position. The casing section of the present invention includes a sleeve which can be moved between a first position in which access to the window opening of casing section is not affected and a second position in which the main casing is sealed from the liner section of a deviated wellbore to provide a hydraulic seal against passage of fluids from outside the casing of the wellbore into the main casing.

摘要： A tool for running and retrieving a whipstock in a subterranean wellbore includes a tool body that has one end that is adapted to be connected to a pipe. The tool body includes a rail defined thereon that is adapted to selectively engage a slot defined on the whipstock. The pipe is in fluid communication with a bore defined in the tool body. The tool body includes a latch assembly for releasably connecting to the whipstock. The latch assembly is adapted to be moved when pressure is applied to the tool bore through the pipe thereby enabling the connection and disconnection of the latch assembly from the whipstock.

摘要： A downhole system includes a deflector with a reaction surface that is engageable to a mill. The deflector is coupled to a motion mechanism that is activable to move the deflector generally along a longitudinal direction. During operation, the mill is engaged to a surrounding downhole structure, and the mill is rotated. As the mill cuts an opening in the downhole structure, the motion mechanism moves the deflector, which allows the mill to move with the deflector. A smooth motion is provided by the motion mechanism to enable a more accurate cutting of the downhole structure (e.g., casing or liner).
