摘要： A stage tool used in a wellbore has a housing consisting of two sub-housings that couple together. A first sleeve is movably disposed in the housing bore and is held closed with a temporary connection relative to a side port of the housing. The first sleeve has a first seat of millable material. A second sleeve is also movably disposed in the housing bore and is held opened with a temporary connection relative to the side port. The second sleeve has a second seat of millable material. An opening plug is landed on the first seat so pressure can break the connection and shift the first sleeve open relative to the side port. After pumping cement out of the tool, a closing plug is pumped to the second seat so pressure can break the connection and shift the second sleeve closed relative to the side port. The first sleeve includes a bypass that allows for fluid to pass beyond the seated plug.

摘要： A flow control apparatus includes a housing having a bore extending and a port formed through a wall of the housing; and a port sleeve disposed in the housing and having a port in communication with the port of the housing. The apparatus also includes a first sleeve releasably attached to the housing, wherein the first sleeve is movable from a first position preventing axial movement of the port sleeve relative to the housing to a second position allowing axial movement of the port sleeve relative to the housing. The apparatus further includes a second sleeve releasably attached to the port sleeve, wherein the second sleeve is movable from a first position blocking fluid communication through the port of housing and the port of the port sleeve to a second position allowing fluid communication through the ports.

摘要： The present invention relates methods and apparatus for lining a wellbore. In one aspect, a drilling assembly having an earth removal member and a wellbore lining conduit is manipulated to advance into the earth. The drilling assembly includes a first fluid flow path and a second fluid flow path. Fluid is flowed through the first fluid flow path, and at least a portion of which may return through the second fluid flow path. In one embodiment, the drilling assembly is provided with a third fluid flow path. After drilling has been completed, wellbore lining conduit may be cemented in the wellbore.

摘要： A crossover tool for use in a wellbore includes: a tubular housing having a bypass port; a mandrel having a bore therethrough and a mandrel port in fluid communication with the mandrel bore, the mandrel movable relative to the tubular housing between a first position where the mandrel port is isolated from the bypass port and a second position where the mandrel port is aligned with the bypass port; and an actuator operable to move the mandrel between the first position and the second position. The actuator includes a first piston connected to the mandrel and a second piston operable in response to the first piston.
