【摘要】：由于黏度大、流動(dòng)性差等,稠油開(kāi)發(fā)和集輸面臨較大的困難,而利用微生物改善稠油的性能比業(yè)界的傳統(tǒng)做法更為經(jīng)濟(jì)、環(huán)保。從遼河油田活性污泥中篩選出一株嗜蠟菌(ZL-7),優(yōu)化出其最佳培養(yǎng)溫度為45℃,培養(yǎng)周期為7d;含菌體的富集培養(yǎng)液(菌懸液)處理稠油7d后,對(duì)稠油有較明顯的降黏、除蠟的作用;利用聚焦光束反射測(cè)量?jī)x(FBRM)監(jiān)測(cè)稠油的粒徑長(zhǎng)度分布(CLD)與粒徑分布(DDD),發(fā)現(xiàn)稠油小粒徑所占比率上升,大粒徑所占比率下降,粒徑平均值較之前有所下降,有利于稠油乳狀液的制備及分離。
[Abstract]:Because of its high viscosity and poor fluidity, heavy oil development and gathering and transportation are facing great difficulties, and it is more economical to use microbes to improve the performance of heavy oil than traditional methods in the industry. Environmental protection. A waxophilic bacterium ZL-7 was selected from activated sludge of Liaohe Oilfield. The optimum culture temperature was 45 鈩，
