Abstract
Disclosed is a method for reducing pressure and increasing injection by continuous operation system of biological acid acidification and nano coating, specifically including composition and preparation method of biological acidizing agent and nano coating agent. The method for reducing pressure and increasing injection by continuous operation system of biological acid acidification and nano coating of the present disclosure is able to effectively dredge the stratum water flow channel, reduce the water flow resistance, and achieve the effect of high-efficiency pressure reduction and injection increase of the water injection well.
