A float shoe is used in the drilling of oil and gas wells. It is a single cylindrical piece that performs the functions of both a float collar and a guide shoe. Its main purpose is to guide drilling equipment to the bottom of the well without snagging, like a guide shoe. It also contains a check valve to allow fluids to pass in only one direction, like a float collar.
As operators drill a well, they line the hole with casing. The casing is a steel pipe of the same diameter as the hole. It prevents the walls of the hole from caving in during the drilling process. It also prevents fluid from seeping into the hole. In the event that petroleum is found at the drill site, the casing is used as a conduit to pump petroleum out of the well.
As each section of casing, or joint, is only 30 feet (9 meters) long, many are needed to reach the bottom of most wells. A series of casings screwed together is called a casing string. The floatshoe is screwed onto the bottom of the casing string to guide the casing to the bottom of the well. It prevents mud from entering the casing. It also helps the casing to float during the descent, which decreases the load acting on the oil derrick and other topside drilling equipment.
Float collar is installed on the casing and up the float shoe. Like float shoe, it also provide buoyancy to the casing string when it's lowered, reducing the load on the drilling rig. A build-in check valve provides buoyancy to the casing string also prevents cement from re-entering the casing after it's displaced. It's a receptacle to cement plug.
Float shoe features:
1. All inner parts are made of easily drillable aluminum alloy.
2. The device can be connected directly to the casing of the same type.
3. Reliable back-pressure leak proof structure, enable grout or slurry flow with less resistance.
4. Valve seat and valve disk can effectively prevent grout from flowing back.
5. Non-rotating landing plate is available on request.
6. Either PDC or rock bit drillable.
