发明名称 WELL SUSPENSION ASSEMBLY
摘要 An assembly for connecting an inner and an outer tubular member to and from each other in a well. A resiliently expandable and contractible locking support element is carried by and is axially slidable on the inner member. Two or more radially outwardly extending and downwardly facing load bearing support shoulders and peripheral locking surfaces are positioned on the inner member and coact with inwardly facing load bearing shoulders and locking surfaces on the locking support element. Two or more radially outwardly facing load bearing support shoulders on the locking support element coact with mating load bearing support shoulders on the inside of the outer tubular member. A release initially prevents axial movement of the locking support element on the inner member and may be positioned above, below or intermediate the ends of the locking support element. The locking support element may be an integral unit or a plurality of multiple separate units. The locking support element may be biased outwardly by various types of spring devices.
