This kind of casing pipe is mainly used for the application of oil reservation layer without much sand or for application of prevents the rock bits dropping off the well bore. This type of casing product can be used for sand rock and carbonate oil reservation. Specially used for horizontal oil well. We can drill standard or customized hole size in any number and pattern.
Perforated casing is designed for creating direct link between the well bore and the producing formation through punched holes in the casing and the cement sheath that surrounds it. It is usually used as a protect casing or supporting pipe of other well screens, such as pipe-based wire wrapped screen The size and distribution of perforated hoses pose a direct impact on well productivity.
