Method for treating a zone of a subterranean formation penetrated by a borehole carbonate well

摘要

Summary "method to treat a zone of a subterranean formation penetrated by a borehole ash pit," a method of treating a zone of a subterranean formation penetrated by a carbonateRifu00edcio wellhead is provided.The method includes the steps of: (a) forming a treatment fluid comprising: (I) water, (II) a polymer soluble in water and having at least one functional group that can be connected across the alumu00ednIO (III); and (III) a carboxylate of aluminium soluble in water; the pH of the fluid treatment is less than 1; (b) introducing the treatment fluid through the orifice of the well to the area; and (c) a multitude of arrays.IRR time for strong acid in the fluid treatment spend in training so that the pH of the fluid increases sufficiently to aluminium of aluminium carboxylate to connect crossed the polymer. 1 / 1
