Quality assurance, price concessions. Oil Casing is a large-diameter pipe, played the role of fixed oil and gas wells, or wellbore wall. Cannula is inserted into the wellbore, the fixed with cement to prevent the borehole spaced formation and borehole collapse and to ensure drilling mud circulation to facilitate drilling mining. Sleeves are used to support oil and gas pipe wall, in order to ensure the drilling process and after completion of normal operation of the wells. Each well depending on the depth of drilling and geological conditions, to use several layers of casing. After cementing casing go down to use it and tubing, drill pipe is different, can not be reused, are disposable consumable materials. Therefore, the casing consumption of more than 70% of all the oil well pipe. Casing according to usage can be divided into: a catheter, surface casing, casing and production casing.
