Study on Profile Control by Microbe in Fracture Reservoirs
摘要
Abstract
The study on profile control by MEOR is systematically carried out in Fuyu Oilfield in view of the growing fractures,serious heterogeneity of the reservoirs,high water cut and ineffective circulation of injected water. Field pilot test of profile control by MEOR was implemented in two typically selected water injection well groups on the bases of the experimental study of JFT — 001 strain behavior of physiology and biochemistry,profile control capacity and drainage efficiency,resulting in cumulative increase in oil production of 4 157 t and decrease in yearly average water cut of 13. 2%. The field test in 33 well groups in Block 12 -3 of the east of Fuyu Oilfield results in cumulative increase in oil production of 27 896 t,decrease in water cut of over 10% in the peak of good response,even 30% for some wells and averagely 3% to 6% in the whole effective period. The deep profile control by JFT -001 strain has the advantages of simple operation,long effectiveness,no contamination to environment,effective increase in production and obvious economic efficiency and will become a largely potential EOR technology for the development in high water cut period of Fuyu Oilfield.关键词
