SEALING EQUIPMENT BETWEEN TWO TUBULAR MEMBERS, APPARATUS FOR FORMATION OF A SEALING BETWEEN INTERNAL AND EXTERNAL TUBULAR MEMBERS AND SEALING EQUIPMENT BETWEEN INTERNAL AND EXTERNAL TUBULAR MEMBERS

摘要

apparatus for sealing between two tubular members, apparatus for forming a seal between inner and outer tubular members and apparatus for sealing between inner and outer tubular members the present invention generally relates to a method and apparatus for sealing between the tubular members and in particular to a metal seal used between two members of an adjustable wellbore lining (116). the apparatus for sealing between two tubular members comprises upper and lower sealing rings (138, 142) joined as an assembly, each having a sealing surface (152, 154, 163) about an inner diameter and an outer diameter ; an energizing ring (146, 260) which extends into the sealing surfaces of the inner diameter (152) of the lower sealing ring (138, 142) and the outer diameter (154) of the lower sealing ring (138, 142) to part forming a sealing engagement with the two tubular members in response to downward movement; and wherein the sealing surfaces (152, 154, 163) of the upper sealing ring (138, 142) are radially deformed in engagement with the tubular members.
