摘要： Embodiments of the hybrid tool string include coiled tubing and jointed tubing, as well as a means typically located at the connection of the coiled and jointed tubing for sealing the fluid flowpath through the bore of the hybrid tool string. Embodiments of the hybrid tool string may use a pressure-activated valve tool attached in series between the coiled tubing and the jointed tubing, which allows for sealing of the bore by application of pressure. Embodiments of the pressure-activated valve tool may use a flapper in conjunction with a sleeve to seal the bore. The novel hybrid tool string may be used to service a well.

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： 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.
