The invention relates to a method for confirming oxygen consuming content and oxygen consumption rate of oil pool microorganisms, comprising the following steps: (1) injecting oil well produced water or oil well injected water containing 0.5-5 percent of nutrient components into a culture vessel by a displacement pump; (2) supplementing the culture vessel with oxygen or air, wherein the volume of the air flow is 1-5 times of that of the water sample; (3) culturing the water sample by simulating the oil pool temperature of 45-80 DEG C and the pressure of 10-20MPa for 5-30 days; (4) taking the water sample for analyzing density counting and community structure of flora; and (5) taking air sample for gas chromatography and calculating the consuming content of the oxygen by combing with the flora counting and analyzing result. The method can confirm the amount of oxygen needed by oil pool microorganisms for effective growth and propagation in different conditions to further calculate the total ...

The invention relates to a composite microorganism oil-displacing agent for improving the oil recovery rate. The composite microorganism oil-displacing agent is prepared by adding mixed liquid containing 1-8 percent of byproducts of triticeae crops, 1-8 percent of byproducts of maize, 0.5-6 percent of byproducts of wood and the balanced of water by weight into 5-10mg/L trace element and 300-500mg/L polyacrylamide, wherein the particle diameters of the byproducts of crops and wood are smaller than 0.5 mm. The composite microorganism oil-displacing agent is filled with the aid of oxygen-containing air, has dual functions of providing nutrition for microorganism and plugging a high permeability zone, can enlarge the swept volume of nutrient fluid and the fermentation range of the microorganism, prolong the acting time between the microorganism and rock and fluid in an oil layer, satisfy the requirement for fermentation time, provide conditions for biological action and biochemical action and ...
