HTHP float collar/shoe is mainly applied in deep well or complex formation, where the formation stress is not stable, the differential pressure between bore annulus and casing is increasing, plus high temperature, leading to the failure of back-pressure valve. This kind of problem can be solved by using HTHP float collar/shoe with valves adopted with temperature -resistant rubber or metal-to-metal for sealing. |
