    Distinction between tubing and casing？

    Tubing is the pipe that passes into the casing of an oil well during normal production. In a nozzle well, oil flows through tubing to the surface and into the collection and transport process. In a mechanical production well, the tubing, rod, and deep well pump (the "triple pump" unit) are combined to bring the oil pump to the surface for collection and transport.
