In this paper, GC-MC is used to determine the organic acids with low molecular weight produced by the microbial degradation of crude oil zymotic fluid. 本文使用气-质联用仪对微生物降解原油发酵液中低分子量有机酸进行测定。
All these compounds produced by bacteria can be emulsified crude oil. These results demonstrate that the specific purpose project strain can also be screened from not only in oil source. 在非油源区一样可以筛选得到特定目的工程菌,可以极大扩大工程菌种来源。
In the phase of high water-cut development, injection of some chemicals can alternate the stratum wettability, adjust oil-water relative permeability and slow down the increase in water-cut of produced fluid, thus raising crude oil productivity. 在油田高含水采出阶段,通过注入化学剂改变地层润湿性来改变油水相对渗透率的方法,能够有效减缓含水率的上升,提高原油产量。
In the later period of oilfield development, high water cut in produced fluid and unstable produced fluid volume may cause big and frequent disturbance in the electric dehydration system of crude oil. 油田开采后期,采出液中含水率很高且采出液量极不稳定,这就导致原油电脱水系统频繁受到大的干扰。
