The invention belongs to the technical field of tertiary oil recovery, and particularly relates to an indigenous microorganism oil recovery method of a medium to high permeable oil reservoir. The indigenous microorganism oil recovery method specifically comprises the following steps that an oil reservoir is screened; indigenous microorganisms are analyzed; an activating agent is screened; a fieldinjection technology is optimized; and a field test is conducted and the effect is evaluated. The indigenous microorganism oil recovery method has the advantages that the technology is simple, the pertinence and the maneuverability are high, the mining cost is low, and subsequent treatment is not needed, and field application and promotion are facilitated; meanwhile, different injection technologies are adopted aiming at the difference of the oil layer penetration rates, the using amount of the injection agents can be effectively saved, meanwhile the use ratio of injected water is increased, the water driving wave and the volume are expanded, so that the development effect of water driving is improved, the field test enhanced oil recovery is larger than 15%, and the input-output ratio is larger than 1:5. Thus, the indigenous microorganism oil recovery method can be widely applied to the technical field of microorganism oil recovery.
