Oil casing is a kind of large diameter pipes, have fixed oil and natural gas oil casing or the role of the hole. Casing is inserted into the hole and fixed with cement, in order to avoid borehole separated strata and borehole collapse, and ensure the drilling mud recycling activities, so that the drilling.
In the process of oil production using different types of casing:
Surface oil casing drilling - maintenance, to prevent polluted by shallow layer and shallow gas, - to support the wellhead equipment and stick to the other layer weight of the casing.
Technology of oil casing - dividing different levels of pressure, so that the drilling fluid lines normal circulation and maintain consumer casing. - so in drilling device installed anti burst, prevent leakage and tail pipe.
Reservoir oil casing, oil and natural gas derived from the storage layer under the surface of the earth. - to maintain the drilling, drilling mud layer. Oil casing consumption, usually is 114.3 mm to 508 mm diameter.
