摘要： A connector which joins two opposing sections of coil tubing or coil tubing to coil tubing tools so as to enable torque applied from one section to be transmitted to the other section is provided. The connector employs varying width and depth grooves into which portions of the sections of coil tubing are deformed so as to create the torque transmitting connection between the connector and sections of coil tubing. Each of the grooves have a narrow width portion and a wide width portion and corresponding shallow depth and deep depth portion. The narrow width portion of one of the grooves is approximately 180° out of phase from the narrow width portion of the other varying width groove.

The spoolable connector has opposing non-circular grooves into which portions of the sections of coil tubing are deformed so as to create the torque transmitting connection between the spoolable connector and sections of coil tubing. The spoolable connector also includes a plurality of parallel radial slots on each opposing end to enhance bending of the connector at the ends as well as a plurality of longitudinal slots at each end to accommodate the weld seam line in the coil tubing. Seals are also provided as well as a sleeve which in use fits over the mid-section of the connector.

摘要： Apparatuses and methods for generating fluid pressure pulses are disclosed. An example apparatus may include a chamber that can collect fluid and an upstream ported disc coupled to a downstream end of the chamber. The upstream ported disc may rotate about a central axis. The upstream ported disc includes an upstream eccentric port that rotates about the central axis as the upstream ported disc rotates. The example apparatus may include a downstream ported disc coupled to a downstream end of the upstream ported disc such that the downstream ported disc remains substantially rotationally fixed relative to the upstream ported disc. The downstream ported disc includes a downstream eccentric port that may align with the upstream eccentric port to form a passageway for fluid to exit from the chamber to outside of the apparatus, at some time in a rotation cycle of the upstream ported disc.

摘要： A well tool can comprise a fluid input, a fluid output and a fluidic oscillator which produces oscillations in a fluid which flows from the input to the output. The fluidic oscillator can include a vortex chamber with inlets, whereby fluid enters the vortex chamber alternately via the inlets, the inlets being configured so that the fluid enters the vortex chamber in different directions via the respective inlets, and a fluid switch which directs the fluid alternately toward different flow paths in response to pressure differentials between feedback fluid paths. The feedback fluid paths may be connected to the vortex chamber. The flow paths may cross each other between the fluid switch and the outlet.
