摘要： Expandable reamers for enlarging boreholes in subterranean formations include a tubular body at least one member positioned in openings in the tubular body. The at least one member is configured to move between retracted and extended positions. A push sleeve is disposed at least partially within the tubular body and coupled to the at least one member. The push sleeve moves axially upward to move the member to the extended position in response to a pressure of drilling fluid passing through a drilling fluid flow path in the tubular body. The push sleeve moves axially downward to move the member to the retracted position in response to a pressure of drilling fluid upon a restrictive element disposed within the fluid passageway. The restrictive element disposed within the fluid passageway may be discarded from the fluid passageway by increasing the flow rate through the drilling fluid flow path.

摘要： An expandable reamer apparatus and methods for reaming a borehole are disclosed, including at least one laterally movable blade carried by a tubular body selectively positioned at an inward position and an expanded position. The at least one laterally movable blade, held inwardly by at least one blade-biasing element, may be forced outwardly by drilling fluid selectively allowed to communicate therewith or by at least one intermediate piston element. For example, an actuation sleeve may allow communication of drilling fluid with the at least one laterally movable blade in response to an actuation device being deployed within the drilling fluid. Alternatively, a chamber in communication with an intermediate piston element in structural communication with the at least one laterally movable blade may be pressurized by way of a movable sleeve, a downhole turbine, or a pump.

摘要： A method for protecting integrity of a core sample during transport from a subterranean formation to the surface comprising: cutting a core sample from the subterranean formation using a drilling fluid; encapsulating the core sample with an encapsulating material that is separate from the drilling fluid and comprises a property which renders the encapsulating material capable of protecting the chemical integrity of the core sample during transport from the subterranean formation to the surface, wherein the property is other than a property selected from the group consisting of a viscosity which increases in response to a decrease in temperature and an ability to solidify in response to a decrease in temperature; and, transporting the encapsulated core sample from the subterranean formation to the surface.

摘要： A stabilizer bearing assembly is described for maintaining separation between a substantially nonrotating inner tube assembly and a rotating core barrel within which the inner tube assembly is disposed. The bearing assembly comprises a cylindrical tube having a cylindrical sleeve segment concentrically slidably mounted on the tube over an external bearing portion thereof. The tube includes an upper and a lower segment, with the hardened bearing portion over which the sleeve sits being located near the lower end of the upper segment. A flange demarcs the upper edge of the bearing portion. The upper end of the lower tube segment is threadedly attached over the lower end of the upper segment. The sleeve segment is trapped between the flange and the edge of the upper end of the lower tube segment. The inner surface of the sleeve has a plurality of spaced longitudinal furrows and the outer surface of the sleeve has raised ridges corresponding to the furrows. The furrows provide a passage for drilling fluid and debris. The ridges have at their tops flattened bearing surfaces which define an outer circumference whose radius is greater than the radius of the outer circumference of the sleeve segment and the tube. The stabilizer assembly can be detachably inserted between adjacent upper and lower elements of an inner tube assembly. For use, one or more of such stabilizer assemblies would be inserted at spaced intervals in an inner tube assembly.
