内源微生物驱油过程中营养激活体系的优化
Optimization of nutrient activation system in endogenous microbial oil displacement
摘要
Abstract
In order to improve the endigenous microbial enhance endogenous microbial nutrient system evaluation experiments were carried out in 1 injection well and 4 wells of the dip 3 blocks in Shaojia Oilfield.According to the bacterial concentration,the biogas production and the emulsifying effect of crude oil, the existing nutrition system was screened and optimized. The optimum nutrition system was as follows:3 g/L plant polysaccharide,1 g/L corn syrup dry powder,2 g/L NaNO3 and 0. 2 g/L(NH4)2HPO4.Under the optimum nutrition condition,the maximum cell density was 4×108 cell/mL,the biogas production could reach 0. 108 MPa,the crude oil recovery rate was 2. 8%higher than that of the original system.Also,acetic acid content reached 600 mg/L,and the surface tension of injected water reduced to 34. 1 mN/m.关键词
