摘要： A sliding valve has a valve body, a sliding sleeve received in a longitudinal bore of the valve body, and a collet receivable in a longitudinal bore of the sliding sleeve. The valve body has one or more fluid ports on an uphole portion of the sidewall thereof. The sliding sleeve is movable between an uphole closed position closing the one or more fluid ports and a downhole open position opening the one or more fluid ports.The sliding sleeve has a sleeve-profile formed at least by one or more sleeve-grooves and one or more sleeve-ridges longitudinally distributed on an inner surface thereof. The collet has a flexible collet-profile formed by at least one or more collet-grooves and one or more collet-ridges respectively corresponding to the sleeve-grooves and sleeve-ridges. The length of each sleeve-ridge or collet-ridge is smaller than that of corresponding sleeve-groove or collet-groove.

摘要： A sliding valve has a valve body, a sliding sleeve received in a longitudinal bore of the valve body, and a collet receivable in a longitudinal bore of the sliding sleeve. The valve body has one or more fluid ports on an uphole portion of the sidewall thereof. The sliding sleeve is movable between an uphole closed position closing the one or more fluid ports and a downhole open position opening the one or more fluid ports. The collet comprises a metal portion about an uphole end of the collet, and a ball seat having a ball-seat surface radially inwardly sloped from uphole to downhole at an acute slope angle with respect to a longitudinal axis of the collet. The metal portion is radially outwardly expandable under a radially outward pressure to form a metal-to-metal seal at the interface between the collet and the sliding sleeve when the collet is received in the sliding sleeve.

摘要： A sliding valve for opening one or more fluid ports in a piping string, having a valve body and a sliding sleeve in a longitudinal bore thereof. The valve body has one or more fluid ports in an uphole portion thereof. The sliding sleeve is movable in the valve body between an uphole closed position closing the one or more fluid ports and a downhole open position opening the ports. The sliding sleeve has a longitudinal bore for receiving a collet, and/or a stop ring and/or a protective sleeve. The stop ring forms a stop shoulder for preventing downhole movement of the collet relative to the sliding sleeve.

摘要： A system and method for successively fracking a wellbore at spaced intervals along tubing having therein frac ports each openably closed by a sliding sleeve. The system has at least one actuation member and at least one cylindrical sand screen sub insertable into the tubing. Each actuation member has a collet sleeve with a radially-outwardly biased protuberance of a first profile configured to matingly engage an interior groove profile on at least one of the sliding sleeves and slide the sliding sleeve downhole to open the corresponding port. Each cylindrical sand screen sub has a dissolvable plug member or burst plate disposed on one end thereof allowing for the sand screen to be forced into the well by pressure acting against the plug or plate, and has a resiliently-outwardly biased protuberance configured for engaging a mating profile on the tubing and retaining the sand screen sub in a desired position.
