Research of Retarded Acid Formula System of Qijiabei Oil Field

Abstract:

In order to overcome the disadvantages of rapid acid-rock reaction rate, short penetration distance, and poor acidification results exist in the process of traditional acidification in Qijiabei oil field, this paper has developed research on retarded acidification technique and optimized its formula and injection parameters. With the operations of complex formulation, screening and optimization among main agent, scale-froming ion inhibitor, permeability-increasing agent、clay stabilizer、corrosion inhibitor、retardant, a kind of retarded unplugging formula with good combination property suits for environment of high temperature has been developed. According to research, this developed formula system has permeability improving rate of 20.5% on natural core, suggest good characteristics of corrosion inhibition, retardation and permeability increasing.
