Abstract
Изобретение относится к нефтегазодобывающей промышленности, в частности к кислотным обработкам терригенных коллекторов и разглинизациии пластов. Кислотный состав не образует осадков при смешении с пластовыми минерализованными водами, обладает низкой коррозионной активностью.The invention relates to the oil and gas industry, in particular to acid treatments of terrigenous reservoirs and clay formation. Acid composition does not form precipitation when mixed with brine saline waters; it has low corrosivity.
