| Float collar and float shoe |
|
Description:
Float collar and float shoe are conventional necessary accessories of casing string substructure, usually connected in the bottom of casing string, used to guide the casing string smoothly into the well, to prevent cement backflow and create pressure then cement solidification after Realizing pressure in the cementing well, decrease derrick load, control height of cement plug. This components of the device processed drillable aluminum alloy , Finally can directly drill.
