SALT OF MONOCHLOROACETIC ACID WITH CHELATING AGENT FOR DELAYED ACIDIFICATION IN THE OIL FIELD INDUSTRY

机译:单氯乙酸盐与螯合剂,用于油田工业中延迟酸化

摘要

The disclosure is directed to a process for treating a subterranean earth formation by introducing a monovalent salt of monochloroacetic acid into said subterranean earth formation in the presence of a chelating agent which comprises at least one carboxylate group having a monovalent counterion and furthermore comprises a carbon chain carrying at least five hydroxyl groups. Preferably the cation of the monovalent salt of monochloroacetic acid is sodium.
