摘要： A drill assembly has a stinger with downward oriented cups including an upper cup and a lower cup. The cups create a loss zone therebetween in a downhole environment. The downhole environment can be a shaft of a well. The loss zone can be filled with cement to plug the shaft. The downward oriented cups isolate the loss zone from the shaft and minimize the hydrostatic pressure above the upper cup.

摘要： A crusher includes a housing having an inlet and an outlet at opposite axial sides, an impeller positioned proximate the inlet of the housing, and a shaft connected to the impeller and extending axially through the housing between the inlet and the outlet. At least two spaced apart support structures hold the shaft in the housing, where a plurality of dynamic blades extending outwardly from the shaft are alternatingly positioned between a plurality of fixed blades extending radially inward from an inner wall of the housing.

摘要： A system includes a first tubular string within a wellbore and a collar coupled to a top of the first tubular string. The collar may include a body extending from a first end to a second end. The body includes an internal ring extending radially inward from an inner surface of the body. The internal ring includes at least two holes extending through a top surface of the internal ring to a bottom surface internal. Additionally, a second tubular string within the wellbore extends through the first tubular string. An outer ring of the second tubular string lands on the internal ring.

摘要： Methods for operating drill strings in a wellbore include providing a drilling apparatus that includes a Kelly drive system for rotating the drill string that includes a bottom hole assembly (BHA) and a Kelly engaged with the Kelly drive system. The BHA includes a hydraulically driven rotating string reamer coupled to the drill string uphole from a drill bit and a near-bit reamer. The hydraulically driven rotating string reamer includes a hydraulic drive operatively coupled to a string reamer. The methods include translating the BHA axially through the wellbore and, while translating the BHA, circulating drilling fluid through the drill string, which causes the hydraulic drive to rotate the string reamer relative to the drill string, drill bit, and near-bit reamer. Rotation of the string reamer by the hydraulic drive reams away imperfections extending radially inward from a wellbore wall of the wellbore.

摘要： A casing string includes an uphole section, a downhole section, and a sealed chamber that is fluidically isolated from the uphole and downhole sections. The sealed chamber extends between the uphole and downhole sections. The casing string further includes a tube that is disposed within the sealed chamber and that fluidically connects the uphole and downhole sections to provide a fluid flow path that extends past the sealed chamber and through the casing string.

摘要： A system displacing cement in an annulus of a well is disclosed. The system includes a casing string with a casing outer circumferential surface, wherein the casing outer circumferential surface delineates a boundary of the annulus and a wiper plug, wherein the wiper plug is placed to follow the displacement of the cement in the annulus. Further, the system includes a float collar, having an outer circumferential surface delineated by the inner circumferential surface of the casing string, configured to allow the cement to pass downward with respect to a surface, and a displacement efficiency calibration collar, having an outer circumferential surface delineated by the inner circumferential surface of the casing string, configured to control volume of the cement displaced in the annulus, wherein the displacement efficiency calibration collar includes a calibration shearing disc.
