摘要： Injection of gas into a managed pressure drilling system to provide for operation of the drilling system in a pressure window defined by the pore pressure of a formation being drilled and a fracture pressure of the formation. The gas is injected through gas injection ports and drilling fluids are allowed to flow between the drilling annulus and the gas injection system though a plurality of flow ports that are disposed vertically below the gas injection ports in the borehole being drilled. The gas injection ports and the flow ports are configured so that when gas is flowing through the gas injection ports, the flow ports are sealed.

摘要： An expandable reamer for a borehole has a plurality of support elements (202) distributed around a central axis of the tool with cutters (234, 236) and stabilising pads (250) on the support elements, arranged such that at least one of the support elements comprises at least one region comprising cutters and at least one support element comprises a stabilising pad having a front surface positioned to face the wall of the borehole. The reamer includes drive mechanism for expanding the support elements (202) radially outwardly from the central axis. The support elements differ in the presence or axial positions of stabilising pads (250) thereon such that at least one support element differs from at least one other support element in the presence or axial position of at least one stabilising pad. This arrangement allows the stabilising pads to be positioned at or close to full gauge, thereby reducing vibration.
