Process for stimulating petroleum production wells

摘要

Process for stimulating petroleum production wells by injecting, into the production well, a solution of higher aromatics (high-flash aromatics) which contains a mixture comprising 50-90% of an oxyalkylated C12-C22-mono- or -di-alkylamine or alkenylamine and 10 to 50% of a petroleum emulsion-breaker. In addition, the solution can also contain oxyalkylated alkylphenols, fatty acids and glycol ethers. This stimulation method produces an excellent influx of oil, a very high oil table and hence a significantly raised rate of production.
