Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of high-efficiency microbial oil displacement injection equipment, belong to the technical field of microbial oil displacement. BACKGROUND

[0002] Microbial oil displacement is a kind of enhanced oil recovery technology with higher technical content, which involves biochemical processes such as growth, reproduction and metabolism of microorganisms in the oil layer, as well as migration of microbial bodies, microbial nutrient solution and microbial metabolites in the oil layer. These processes and the interaction of rock, oil, gas and water can cause changes in their physical properties, thereby improving oilfield production and recovery. The principle of microbial oil displacement is mainly to use the metabolic activity of microorganisms to reduce the viscosity of crude oil and increase the oil production rate. Microorganisms can decompose high molecular organic matter in crude oil to produce some active metabolites, such as adsorbents, surfactants and biopolymers. These substances can change the physical and chemical properties of crude oil, reduce the viscosity of crude oil and increase the interfacial tension of oil and water, thereby improving the recoverability of crude oil. Specifically, the surfactant in the microbial metabolite can reduce the interfacial tension of oil and water, making it easier for crude oil to be driven out by water; while the biopolymer can increase the viscosity of water and improve the sweep efficiency.

[0003] Microbial oil displacement refers to the use of microbial reproduction to reduce the viscosity of crude oil to increase the oil production rate. By injecting microbial activators (including bacterial solution and nutrient solution) into the formation, the problem of blockage may occur after injection due to the presence of more impurities in the extracted microbial activators. Long-term injection can cause blockage due to the collection of impurities, resulting in a slow injection speed and affecting the injection efficiency. In addition, during the injection process, the mixing effect of the microbial activators is poor, which can cause uneven distribution after subsequent injection due to the aggregation of microorganisms, resulting in poor oil displacement effect after microbial injection.
