Special Field Eor Polyacrylamide

Special field eor polyacrylamideBoyuan water purifying has been with several well-known domestic oil field in-depth cooperation for 15 years.Such as:Shengli Oil field/Daqing Oil field/Zhongyuan Oil field ect.Polyacrylamide for Special-purpose EOR in oil field,in constant cooperation also,product getting maturity.Technology Department of Boyuan water purifying tens of thousands of studies for EOR in oil field.And maked out efficient high molecular weight,high viscosity polyacrylamide. Boyuan in the experiment and production,use pre adding alkali hydrolysis process,two stage polymerization,acrylamide as main monomer,the molecular weight of the polymer is more than 25 million in aqueous solution,viscosity than 40cp,degree of hydrolysis at 23%-27% of novel super high molecular weight anionic polyacrylamide.The optimum technological conditions are obtained through a large number of experiments:dosage 200ppm of initiator Y1,potassium potassium sulfate 10ppm,Sodium Bisulfite 150ppm,PH of polymerization process is 8.5-9.5,polymerization concentration 23%,polymerization temperature 10℃,additive agent:urea 5%,Sodium formate 50ppm.Using this method to produce the products sold to Shengli Oil field,Daqing Oil field,Zhongyuan Oil field ect,both greatly improve the original recovery ratio,greatly reduce the cost of oil production.Boyuan EOR in oil field for polyacrylamide after 10 years of market test,has established the leading products in the industry status.Please rest assured that cooperation,buy product of Boyuan,your first choice.
