Development and application effect analysis of solid particle scale inhibitors
In view of the oilfield production wellbore scale and conventional liquid scale in-hibitor additives are not uniform,effective components loss speed,scale inhibition efficiency is low,and so on,a slow-release solid particle scale inhibitor was developed in laboratory.Solid particle scale inhibitors are prepared by using maleic anhydride,2-acrylamide-2-methylpropanesulfonic acid,phosphonic acid and acryloxyethyl trimethylammonium chloride as monomers,the copolymer was polymerized by adding water-soluble persulfate initiator.The carrier was polyvinyl alcohol 1788,which was prepared by kneading,extruding and granula-tion technology.Indoor evaluation shows that the product has the advantages of regular shape,slow dissolution and release rate,and good scale inhibition performance.The field application shows that the solid particle scale inhibitor has the advantages of long adding period,good scale inhibition effect,obvious economic benefit and good industrial application value.
