摘要: An investigation of the areal distribution and time course changes in activity deposit microflora after injection nutrients (distillery mollasses) into was carried out three oil-bearing areas. The number sulphate-reducing bacteria were determined water. infiltration from well to production bores assessed increase water injection; speed calculated on basis “mean proliferation time” for individual wells. results showed that microbiological method can be used ascertain connections between well. In assessing it is also possible direction most rapid slowest estimate permeability collector various directions.
