稠油降解菌的筛选于降解效果评价

Screening of Thick Oil-degrading Bacteria and Its Degradation Effect

微生物驱油技术的主要机理之一就是利用微生物降解原油中含有大组分,降低原油粘度,进而改变原油的物性。利用原油以及含油污水中筛选出能降解稠油的菌组进行实验,结果表明,微生物作用使原油物性发生明显变化,原油中的胶质、沥青质含量降低,组分也发生了明显变化,原油物性变化明显。

One of the main mechanisms of microbial oil recovery technology is to reduce the viscosity and freezing point of crude oil by using microbial degradation of the main components such as gum and asphaltene in crude oil, so as to improve the physical and chemical properties of crude oil.In this paper,the experiment was carried out to isolate and select the bacteria to effectively degrade the heavy oil.The results show that the properties of heavy oil have been changed obviously with the action of bacteria, and the contents of each component in the heavy oil are decreased, and the composition and structure of the heavy oil are changed obviously.
