【摘要】：油田回注污水常用殺菌劑為陽離子型季銨鹽類殺菌劑,在聚合物驅(qū)油注水系統(tǒng)中,季銨鹽類殺菌劑常與采出水中殘留的聚合物發(fā)生反應(yīng)而喪失殺菌效果,當(dāng)投加量為60 mg/L時殺菌率僅為80%。殺菌效果不好,不僅引起管道設(shè)備的細菌腐蝕,而且細菌還會降低聚合物黏度,因此,需要研發(fā)不易與聚合物反應(yīng)的殺菌劑。以氯化芐和二乙烯三胺為原料,合成了低分子質(zhì)量有機胺類殺菌劑,通過單因素實驗以及正交設(shè)計實驗確定了合成殺菌劑的最佳工藝方案,當(dāng)溶質(zhì)質(zhì)量分數(shù)為60%、反應(yīng)介質(zhì)為1,4-二氧六環(huán)、反應(yīng)溫度為50℃、反應(yīng)時間為2.5 h、攪拌速度為120 r/min時,反應(yīng)物轉(zhuǎn)化率可達到96%以上。在含聚污水中加入該殺菌劑進行評價,當(dāng)投加量為60 mg/L時殺菌率可達到98.1%。
[Abstract]:The commonly used fungicides in oilfield wastewater are cationic quaternary ammonium salts. In the polymer flooding system, quaternary ammonium salts often react with the residual polymers in the produced water and lose their bactericidal effect. When the dosage is 60 mg / L, the germicidal rate is only 80%. The bactericidal effect is not good, not only causes the bacteria corrosion of the pipeline equipment, but also the bacteria will reduce the polymer viscosity, therefore, it is necessary to develop the bactericide which is not easy to react with the polymer. Low molecular weight organic amines were synthesized from benzyl chloride and diethylenetriamine as raw materials. The optimum process of synthesizing fungicides was determined by single factor experiment and orthogonal design experiment. When the mass fraction of solute is 60, the reaction medium is 1: 4- dioxane, the reaction temperature is 50 鈩，
