基于生物基表面活性剂的油田解堵增注体系开发
Development of oilfield decongestion and injection system based on bio-based surfactants
摘要
Abstract
By the study of the performance characteristics of bio-based surfactant 8901A,a composite decongestion and injection system with bio-based surfactant 8901A as the main agent was developed for different low-permeability oil reservoirs and thick oil reservoirs under different temperature conditions.The results showed that the composite decongestion and injection system can reduce the oil-water interfacial tension and reach the state of ultra-low oil-water interfacial tension,and the static oil washing efficiency of the oil sands can reach more than 85%,and the pressure reduction rate can be reduced by an average of 21.55%.This can increase the oil recovery rate by 13.54%,enhance the dissolution ability of the system on the oil plug,and then play a role in decreasing the injection pressure brought by organic plugging,thus increasing the injection volume of injected wells to achieve the effect of improving the oil recovery rate.关键词
