摘要： A drilling system includes a drillstring and a power section further including a stator having a stator axis and a rotor within the stator. The rotor rotates eccentrically within the stator in response to fluid flowing therebetween. Additionally, the system includes a coupling section including first, second, and third rotation members having a first, second, and third axes, respectively. The third rotation member is coupled to the first and second rotation members. The third rotation member is configured to move radially relative to the first and second rotation members as the first, second, and third rotation members rotate about the first, second, and third axes, respectively. Further, the system includes an input shaft coupled to the rotor and first rotation member. The input shaft and first rotation member rotate with the rotor eccentrically to the stator axis and the second rotation member rotates concentrically about the stator axis.

摘要： A method and system for detecting material loss in a tubular. A method includes identifying a radial cross-sectional area of a tubular as having a loss of material in a wall of the tubular. Responsive to the identifying, an amount of voltage offset present in each of a plurality of measurement signals is determined. Each of the measurement signals provides measurement information for an arc section of the wall. For each of the measurement signals, a zero adjusted signal is produced by adjusting the measurement signal to remove the amount of voltage offset over a length of the tubular for which the identifying recognizes the loss of material. An assessment of wall material loss is produced for each arc section of the wall of the tubular based on the zero adjusted signals. An image of the wall of the tubular showing the wall material loss for each arc section is generated.

摘要： A choke with reduced cavitation and/or flashing due to a high pressure fluids passing through the choke includes a housing having a high pressure inlet port and a low pressure outlet port, and a cage positioned within the housing and having a passage for passing fluid therethrough. A plurality of beads are each positioned in the cage, such that fluid flows between the cage and the beads and between the beads when passing through the cage. Fluid pressure is reduced by the fluid passing through the cage, thereby reducing cavitation.

摘要： A tool (100) for working the internal bore of a tube comprises a motor (10), having a housing with a rotary output; a housing sleeve (14a) and shaft (22); a first bearing housing (16), having a rotatably journalled first spindle (102), mounted on the housing sleeve; and an end sleeve and shaft connected to a tool head. The motor output drives, along a common axis (1), the housing shaft, first bearing spindle, end shaft and tool head. A change mechanism (56,58) is in the tool head to change direction of said drive to transverse said common axis. An output (60) is adapted to receive a tool bit. Gauge means (18,18′) is disposed on said tool head and is adapted, in use, to bear against the bore of the tube and maintain the tool head located radially with respect to the tube axis; and support means (24,24′) is disposed on one or more of said housing shaft, first bearing housing and end sleeve adapted, in use, to bear against the bore of the tube and support the tool. A long length of tool can work the inside of long tubes.

摘要： The invention pertains to methods and apparatus for monitoring loads on an arched tubing guide of a coiled tubing injector caused by tension on coiled tubing. The load is sensed by a load sensor, for example, a load cell placed in a strut that supports the arched tubing guide, or in a load pin or load cell placed within the structure arched tubing guide or the connection of the arched tubing guide to a frame for the coiled tubing injector, at a location where the load is representative of the load placed on an arched tubing guide by tension in the coiled tubing. The load sensor generates a feedback signal. The load is monitored, either by an operator or a controller, and torque applied to a reel around which the tubing is wound is adjusted to avoid, or in response to, excessive loads on the arched tubing guide.

摘要： A collapsible drilling rig substructure is transported to a drilling site while in a collapsed transportation configuration wherein a raisable floor of the substructure is in a lowered transportation position relative to a fixed drill floor such that an upper surface of the raisable floor is positioned at a first height level above a base of the substructure while an upper surface of the fixed drill floor is positioned at a second height level above the base that is greater than the first height level. The substructure is positioned adjacent to a wellbore location at the drilling site and reconfigured from the lowered transportation configuration to a raised operating configuration by raising the raisable floor to an operating position laterally adjacent to the fixed drill floor while maintaining a height level of the upper surface of the fixed drill floor at the second height level.
