Packing element with full mechanical circumferential support

摘要

A packer device for forming a fluid seal between an inner tubular member and an outer tubular member. The packer device includes a swage assembly that is expandable from a reduced diameter condition to an expanded diameter condition and a substantially deformable packer element for contacting and forming a fluid seal against a surrounding tubular. The packer element radially surrounds the swage assembly and being moved outwardly into a sealing configuration when the swage assembly is moved to its expanded diameter condition.

1. A packer device for forming a fluid seal between an inner tubular member and an outer tubular member, the packer device comprising:
a swage assembly that is expandable from a reduced diameter condition to an expanded diameter condition; a substantially deformable packer element for contacting and forming a fluid seal against a surrounding tubular, the packer element radially surrounding the swage assembly and being moved outwardly into a sealing configuration when the swage assembly is moved to its expanded diameter condition; and the swage assembly and packer element being secured to a running string that is used to dispose the swage assembly and packer element into a wellbore, the running string having a central fluid flowbore through which fluid is pumped to the packer device.
