| titleOfInvention | Method for regulating and controlling diversity of endogenous microorganisms in oil reservoir and improving recovery ratio |
| abstract | The invention discloses a method for regulating and controlling the diversity of endogenous microorganisms in an oil reservoir and improving the recovery ratio, which comprises the following steps: sampling an oil reservoir on site; pretreating a sample; analysis of endogenous microbial community structure; calculating the diversity of the endogenous microorganisms; determining a preliminary regulation and control scheme; determining a final regulation and control scheme; and (4) carrying out field implementation. The method has the characteristics of reasonable method, simple process, simple operation, safety, reliability, low investment and low cost, and can be used for specifically regulating and controlling the production dynamics in the field implementation process, effectively prolonging the effective period of the endogenous microorganism oil displacement field test and improving the field test effect. Therefore, the invention can be widely used in field tests for improving the recovery ratio of endogenous microbial oil displacement. |
