Complex alkaline decomposer “HimBreak” is composed of a mixture of organic and non-organic matters having high activity towards many compounds of various chemical origin. “HimBreak” has some properties of corrosion inhibitor, preventing failure of downhole equipment.
“HimBreak”, within 6 to 8 hours, decomposes crosslinked gels of the brands and systems on the basis of polyacrulamide to the state of complete decomposition, which makes it possible to use it for restoration of native permeability of reservoirs. “HimBreak”, when it penetrates into the pores and fractures of a reservoir, dissolves contaminants of the reservoir, making it possible to avoid formation contamination with iron hydroxide, plaster stone, decomposing formed filter cake. To decompose the gels, treatments are carried out on the basis of 1 part of “HimBreak” per 5 parts of the gel, which needs to be decomposed. Cyclic pumping of the product is used to remove saline deposits from the downhole equipment.
