    摘要: A wellhead housing has a telescoping casing hanger with an actuator mechanism to provide for direct transfer of casing and pressure loads to the housing. The transfer of casing and pressure loads occurs even in conditions where the telescoping casing hanger may be set in a high position in the wellhead housing on a load shoulder. The transfer of casing and pressure loads also occurs in conditions where the telescoping casing hanger may be set in an earlier installed casing hanger in the wellhead housing for a larger diameter casing string.
