从中原油田现场取样的污水中培养出的硫酸盐还原菌（简称ＳＲＢ），可在聚合物驱油中生长繁殖并使水解聚丙烯酰胺（ＨＰＡＭ）发生降解；当接种的菌量为３．６×１０４个／ｍＬ时，经恒温３０℃７天的培养，１０００ｍｇ／Ｌ的ＨＰＡＭ溶液的粘度损失率可达１９．６％。研究表明，菌体接种量的大小、溶液的ｐＨ值及ＳＲＢ在ＨＰＡＭ溶液中的连续活化次数对ＨＰＡＭ的降解都有影响。
Sulfate-reducing bacteria (referred to as SRB) cultivated in the sewage sampled from the Zhongyuan oil field can grow and breed in the polymer flooding and degrade the hydrolyzed polyacrylamide (HPAM). When the amount of inoculum is 3.6 × 104 / mL, the temperature of 30 ℃ 7 days of culture, 1000mg / L HPAM solution viscosity loss rate of up to 19.6%. The results showed that the inoculation amount of bacteria, the pH value of the solution and the number of SRB continuous activation in HPAM solution all affected the degradation of HPAM.
