Methods of treating a subterranean formation including a biocidal treatment |
摘要 |
A method of treating a subterranean formation including with a bactericidal fluid is provided. The method comprises the steps of: (a) continuously mixing to obtain a stream of a treatment fluid: (i) a base fluid comprising water; (ii) an aqueous solution comprising a hypochlorite having a pH equal to or greater than 7; and (iii) a pH-adjusting agent selected to be capable of lowering the pH of water to less than 7; and (b) injecting the treatment fluid into a wellbore. The step of continuously mixing the base fluid, the aqueous solution of hypochlorite, and the pH-adjusting agent is preferably under conditions and in proportions sufficient to obtain a stream of a treatment fluid having a free chlorine concentration of at least 1 ppm by weight of the water in the treatment fluid and having a pH in the range of 4-7.
