Float collar and float shoe is one of the conventional and necessary accessories of lower casing string structure, usually connecting at the bottom of the tubing string, used to guide the casing string smoothly into the hole, playing a suspended casing, preventing the cement slurry reverse flow and realization of condensation after cementing bump pressure discharge pressure, reducing derrick load, controlling the height of cement plug. The internal components of the device is processed by the aluminum alloy with good drillability, using 9 5/8 "float collar and float shoe after cementation, being able to directly drill down three.
Float collar and float shoe are improved product developed by ourselves based on the modern technique inland and overseas. The inner component of the equipment is made up of drillable aluminum alloy, has the advantage of special configuration high tensity ,light, strong pressure bearing, and good air proof capability, can be applied widely.
