发明名称 SELF-INSERTING SEAL ASSEMBLY
摘要 A self-inserting seal assembly that sets a seal at a well component to allow for pressure testing of the well component. The seal assembly can be landed on a well component with an ROV. A seal is located on the lower portion of a lower body in the assembly. A set of outer dogs lock with a grooved mating profile formed on the well component to lock the outer housing to provide a reaction point for setting the seal, which may require several thousand pounds of force. A set of inner dogs lock with a grooved mating profile formed on the inner diameter of the outer housing. This locks the lower body to the outer housing to ensure the seal remains set in place. After the well component is pressure tested, the seal assembly can be unlocked and retrieved from the well via an ROV.
