Seamless Steel Pipe

    Various impurities can be reduced into the production layer: after acidifying the conventional oil casing pipe, the wax, rust residue and adherent instruments in the pipe will be brought to the formation. If we acidify the thickened tubing to the outside, magazines such as scaling, waxing, and rust residue in the tubing can be removed to reduce the pollution of the tubing to the formation during construction.     To avoid secondary pollution to the oil layer when performing well killing operations: One of the effective methods to improve oil production fluids is to quickly clean the formation. The reason is that after the formation is treated with acid solution, precipitation and liquid leakage will occur. The outer thickened tubing can be used to easily replace the formation with nitrogen, and the outer thickened tubing can be lifted out of the wellhead without well killing. Because the outer thickened oil pipe is a relatively closed loop system, the staff can...
