摘要： A downhole tool for removing debris from a wellbore comprises a body having a bore, a collection member, and a means for creating a hydraulic barrier within a wellbore annulus. The hydraulic barrier within the wellbore annulus restricts upward movement of a debris laden fluid within the wellbore annulus causing the debris laden fluid to be directed toward the collection member. Thus, the hydraulic barrier facilitates removal of debris from the wellbore.

摘要： A downhole tool for removing debris from fluid flowing through the downhole tool comprises a screen member and wiper member, the wiper member having at least one window disposed through the inner and outer wall surfaces of the wiper member. Either the screen member or the wiper member is rotatable such that rotation of the screen member or the wiper member causes debris disposed on the outer wall surface of the screen member to fall-off the screen member. At least one directional port disposed at either the upper end of the screen member or the upper end of the wiper member causes rotation of the screen member or wiper member when fluid flows through the downhole tool.

摘要： Seats for receiving a plug member comprise a tubular member having a seat disposed therein and a fluid flow reduction member that reduces the velocity of the fluid flowing through the tubular member as it approaches the seat so as to reduce the impact of the plug member landing on the seat. The fluid flow reduction member may be disposed on a fluid flow reduction device, such as on an inner wall surface of a sleeved insert, or formed in the inner wall surface of the tubular member. The fluid reduction member can comprise one or more longitudinal channels, one or more apertures, or one or more curved-shaped grooves disposed either on the inner wall surface of the tubular member or on a fluid flow reduction device, such as on an inner wall surface of a sleeved insert disposed within the tubular member.

摘要： A downhole tool for moving fluid through the tool comprises a rotatable sleeve disposed within a bore of the tool. The sleeve includes an opened upper end and a closed lower end to define a cavity. A fluid movement profile is disposed along the lower end. A directional port is disposed in the side of the sleeve in fluid communication with the cavity and an upper port disposed in the tool. The upper port can be isolated from a lower port in the tool, the lower port being in fluid communication with the fluid movement profile. A first fluid flowing downward enters the cavity, exits the directional port causing rotation of the sleeve, and flows out the tool through the upper port. Sleeve rotation causes a second fluid to be drawn upward into contact with the fluid movement profile which directs the second fluid out of the lower port.

摘要： Downhole tools for pumping an acid into a wellbore prior to pumping a fracturing fluid comprise a housing and an actuator member disposed therein. The housing comprises a port that is initially placed in fluid communication with an acid so the acid can be pumped into the wellbore and is then placed in fluid communication with a fracturing fluid so the fracturing fluid can be pumped into the same location within the wellbore. The downhole tool may comprise a chamber having the acid disposed therein. Alternatively, the acid can be part of an acid slug disposed at a leading edge of a fracturing fluid being pumped through the downhole tool.

摘要： Apparatuses for restricting fluid flow through a well conduit comprise a tubular member having an inner wall surface defining a bore and a seat in sliding engagement with the inner wall surface. Operatively associated with the seat is a plug element support member having an expanded position when the apparatus is in a run-in position and a contracted position when the apparatus is in a set position. A plug element adapted to be disposed into the bore and landed on the seat to restrict fluid flow through the bore and the well conduit is used to move the seat which in turn moves the plug element support member from the expanded position to the contracted position, thereby providing support to the plug member landed on the seat.

摘要： Downhole cutting tools comprise a mandrel, a housing, a sleeve and a cutting blade. The mandrel comprises an inner wall surface defining a bore, and an outer wall surface. The housing is secured to the outer wall surface of the mandrel and comprises an opening. The sleeve is engaged with the outer wall surface of the mandrel. The sleeve comprises a profile that is operatively associated with a profile of the cutting blade such that movement of the sleeve causes the profile of the piston to slide along the profile of the cutting blade. In so doing, the cutting blade is radially extended outward through the opening in the housing to abrade an object located outside the housing. Movement of the sleeve can be achieved by pumping fluid down a bore in the mandrel to slide the sleeve long the outer wall surface of the mandrel.
