摘要
克拉玛依油田从优化原料组成结构、优化磺化工艺入手,研究出适合二元驱油用的石油磺酸盐原料;利用高效喷雾分散方式,大幅度提高磺化气液接触面积,解决了生产技术瓶颈,实现连续清洁化工业生产;创新表活剂复配增效技术,完善了二元驱油体系配方,实现了无碱条件下的超低界面张力,模拟岩心驱油效率达到20%以上。
Karamay Oilfield researched and developed the petroleum sulfonate that is suitable for binary flooding. The application of efficient spray dispersing mode has greatly improved the contact area of sulfonated gas and liquid,resolved the bottleneck of production technology and realized continuous clean industrial production. Meanwhile,the innovative surfactant formulation and synergistic technology perfected the formula of binary flooding fluid and realized ultra- low interfacial tension under alkali-free condition with simulated core flushing efficiency reaching to more than 20%.
