Oil pipe and casing are indispensable tools in oil exploitation.

Tubing is the pipe that runs into the oil casing of an oil well during normal production. From the gusher well, the oil flows to the surface using tubing and into the gathering process. In mechanical production Wells, oil pipes, sucker rods, and deep well pumps (known as "three pumping" machines) pump oil out of the surface and into the gathering process.

The oil casing is the pipe put into the well after the completion of drilling. The oil casing and the wall of the well are sealed with concrete, and then the perforating gun is used to aim at the target layer to perforate, so that the oil flow through the rock layer, concrete ring, oil casing into the bottom of the well, and then into the pipe to the surface. The specific functions are: 1, fixed shaft wall, avoid formation collapse; 2. Separate different oil layers and water layers to realize layer-by-layer mining; 3. It is conducive to the completion of fracturing, acidification and other measures and maintenance operations. 5, the establishment of oil flow channel, with tubing to achieve the goal of oil recovery.

The sequence is: after the well is done, the oil casing is put into the oil casing, the oil casing and the well wall are sealed with concrete, and the oil pipe is put into the oil casing. The oil pipe is equipped with downhole tools such as oil packer and pump. The sucker rod is put into the oil pipe, and the sucker rod pulls the piston rod of the pump to move up and down repeatedly. This brings the oil to the surface.
