Rotary Shoe

Rotary Shoe

Rotary Shoes, manufactured from specially heat-treated alloy, provide the ultimate in toughness and durability. This tool is used to cut a clearance between the fish and the wall of the wellbore. Each shoe is designed to fit a particular downhole need and is run on the bottom of the washover string. Shoe design is dictated by where it will cut: on the bottom, on the outside diameter or on the inside diameter. When hole size permits, additional clearances can be cut by using side ribs to enable greater circulation. [Note: Because the inner milling tooth diameter of rotary shoe is large, the reverse torque is large, so low pressure and slow rotation mode should be adopted in the use of rotary shoe. In general, the drilling pressure should not exceed 10 KN and the rotational speed should not exceed 50 r/min.]
