Structure Optimization and Application of Hydraulic Internal Cutter for Well Abandonment Operation in Offshore Oilfield
Large size hydraulic cutter is widely used in offshore well abandonment operation.At present,the hydraulic cutter with large cutting torque,strong vibration and large blade loss can not directly judge the casing pipe cutting condition in the cutting process,resulting in the situation that one side of the casing is cut and the other side is not cut.Therefore,this paper proposes to improve this size cutter and establish the hydraulic parameters calculation of the hydraulic internal cutter and the improvement system calculation of blade material,structure and shape,which can cut the casing pipe completely under the condition of casing pipe eccentricity,is of great significance for offshore well abandonment operation.
