Abstract
Sca ling in W ei 2 fau lt block o ilfield is m ore and m ore obv ious as thew ater cut increases continuously, and beg ins to affect the o ilfie ld deve lopm ent effectiveness. Th is paper stud ies the sca ling m echan ism and discusses its m a jo r influenc ing facto rs by m eans of analyzing sca le characteriste ics , in jec tion wa ter and form ation w ater and simu la ting sca ling experim ents. From this, it presents the m ethod o f optim izing production param eters o f prlduction w e lls fo r decreasing the influence of scaling on the prlduction w e lls, wh ich has been put into field use and has got satisfac tory effects.
