WELLBORE SEALING ASSEMBLY WITH GROOVES FOR ENHANCED SEALING AND LOCKDOWN CAPACITY

摘要

A wellbore system includes a sealing assembly (124) for creating an annular seal between wellbore members (102, 104). The sealing assembly includes a seal body (126) having a u-shaped cross section, with elongate grooves (144, 148) formed on inner and outer walls thereof. A depth of the grooves varies along a length of the grooves to allow wickers (W) to penetrate the groove by differing degrees when the walls are urged toward the wickers. The wickers can thus provide a high degree of both sealing and lockdown performance.
