摘要： A reaming tool includes a housing having a connection at one end for coupling to a pipe string. The housing defines at least one of a rotor and a stator of a turbine. A rotor shaft is rotatably supported on the housing. The rotor shaft has an interior passage and defines the other of a stator and a rotor of the turbine. The rotor shaft has a coupling at one end to attach a well intervention tool. A flow diverter is disposed within the housing. The flow diverter comprises ports to selectively direct flow of fluid from an interior of the housing to either (i) an annular space between the housing and the rotor shaft, or (ii) the interior passage of the rotor shaft. The flow diverter is operable to change direction of the flow of fluid by changing a flow rate of the flow of fluid.

摘要： A multifunctional drilling enhancement tool includes a shaft having a bore extending along a longitudinal direction (X); a main cutting device rotatably and slidably attached to the shaft; a first housing fixedly attached to a first end of the shaft; a second housing fixedly attached to a second end of the shaft; first and second proximal engagement elements attached to opposite ends of the main cutting device; and first and second distal engagement elements attached to corresponding ends of the first and second housings, so that the first distal engagement element is directly facing the first proximal engagement element, and the second distal engagement element is directly facing the second proximal engagement element. The first distal engagement element has removable first distal inserts, the first proximal engagement element has removable first proximal inserts, and the first distal inserts are configured to directly contact the first proximal inserts to transmit a rotation from the first housing to the main cutting device.

摘要： A drill assembly comprises a drill shoe body has a substantially triangular cross-sectional configuration, an upper surface portion of the drill shoe body comprises forward and rearward sections which are disposed at a predetermined angle with respect to each other, oppositely disposed lateral sides of the drill shoe body taper laterally outwardly from the front end of the drill shoe body toward an intermediate transverse plane, while oppositely disposed lateral sides of the drill shoe body taper laterally inwardly from the transverse plane toward the rear end portion of the drill shoe body. Multiple, spaced apart drill bits are disposed upon a front end of said drill shoe body, oppositely disposed lateral sides of the drill shoe body, and oppositely disposed flank portions of the drill shoe body so as to assist the drill shoe body in acting as both a pilot bore drilling tool and as a reaming tool in connection with a drilled bore.

摘要： An auger-suction type metro jet system (MJS) device for aerated and lightweight cement soil includes a multi-pipe device, an outer sleeve, an integrated device, a spiral conveyor, a reamer head, a pressure monitoring system, a mass measuring device, and a control console. The multi-pipe device integrates a backup pipe, a negative-pressure gas pipe, a hydraulic pipe, a negative-pressure water pipe, a pressure sensor wire pipe, a pressure water pipe, a backup gas pipe, a power wire pipe, and at least one grouting tremie unit. The spiral conveyor includes a shaft-type spiral conveying belt and a negative-pressure device. A construction method for foundation reinforcement construction includes: cutting soil by the reamer head; crushing gravel by a gravel crusher; transporting, by the shaft-type spiral conveying belt, a soil-water mixture to a waste liquid tank; monitoring, by the mass measuring device, a mass of the soil-water mixture discharged; and injecting equal-mass cement.

摘要： A reaming tool forms a hole in the ground with a sidewall and a floor, and a deepened channel around the perimeter of the floor adjacent to sidewall. Fluid is provided during excavation to form a slurry to hold the sidewall and prevent cave-in of material into the hole. After the hole reaches a desired depth, the reaming tool is removed, and a shoring wall is inserted into the hole through the slurry and seated in the perimeter edge channel. The shoring wall includes vertical tubes for connection to a dewatering machine. Then, the slurry can be vacuumed from the hole, while the dewatering machine keeps the empty hole as dry as possible. Extending the shoring wall into the channel beyond the floor of the hole helps seal flow of water from entering the hole.

摘要： A downhole tool, for removing a restriction in a well tubular metal structure having a wall and an inner diameter, has a tool axis and a tool body having a first part and a second part, an electrical motor arranged in the first part for rotating a rotatable shaft, and a core bit arranged in the second part and having a first end connected with the rotatable shaft and a second end having a cutting edge. The second part of the downhole tool further includes a locator for locating the rim section, the locator being rotable with the core bit until the locator locates the rim section and a threshold value is reached.

摘要： A downhole tool, for selectively reaming a wellbore or stabilizing drill string components within a wellbore, includes an elongate tool body adapted to receive reamer cartridges or stabilizer cartridges depending on the function desired. The reamer cartridges are radially insertable into corresponding pockets in the tool body, with each reamer cartridge having a reamer insert with an array of cutting elements. The reamer insert is disposed within a bushing and is rotatable relative thereto, about a rotational axis transverse to the longitudinal axis of the tool. However, the rotational axis is offset from the tool body axis, resulting in eccentric contact of the cutting elements with the wall of the wellbore, which in turn imparts rotation to the reamer insert when the tool is being moved axially through a wellbore without rotation. When the tool is to be used for stabilization, the reamer cartridges can be removed and replaced with stabilizer cartridges having stabilizer inserts with hard-faced stabilizer cones.
