注入水中微生物对特低渗透储层伤害评价及推荐指标
EVALUATION AND RECOMMENDED INDEXES FOR THE ULTRA-LOW PERMEABILITY RESERVOIR DAMAGE BY THE MICROBILE IN THE INJECTED WATER
摘要
Abstract
Researches on the damage laws and recommended indicators to the ultra-low permeability reservoir caused by the microbiles in the injected water have important guiding roles for the fine and effective water injection development of this kind of the oilfield.Based on the analyses of the microbial properties in the injected water and the pore throat characteristics of the ultra-low permeability reservoir,three kinds of the microbile (Sulfate reducing bacteria-SRB,iron bacteria-IB and total growth bacteria-TGB) were considered with three different microbial concentrations for twenty-seven core flow experiments with three levels of the ultra-low permeability.The results show that the injection concentration,injection rate and compatibility (The matched degree between the self-configuration and reservoir pore throat) of the microbile are three leading factors that influence the permeability loss value of the ultra-low permeability reservoir;with the rise of the injection concentration,injection rate and compatibility of the microbile,the ultimate permeability loss value will be increased;for the three microbiles stated above,the rule of the damage degree to the reservoir is presented as SRB>TGB＞IB,SRB should be used as the key control index.For the ultra-low permeability reservoir,the microbial controlling indicators in the injected water were recommended.关键词
