Optimum Ratio Experiment Research on Autogenous Nitrogen Acid Catalyzed Fracturing Fluid

  • 摘要: 针对我国煤储层“渗透率低、储层压力低和含气饱和度低”对煤层气开发的不利条件,提出自生氮酸催化压裂液体系,以实现煤储层的增透,增能和增温效果。通过实验分析了生氮剂和催化剂配比对反应速率、产气量的影响;确定了适用于煤储层压裂的最佳生氮剂摩尔比2.5︰1,最佳生氮剂质量浓度8%~12%和反应液pH(4~5);探讨了不同温度对反应速率和产气量的影响;同时分析了不同酸的催化效果。
    Abstract: According to the negative factors that "low permeability, low reservoir pressure and low gas saturation " of China's coal reservoir, the system of authigenic nitrogen acid catalytic fracturing fluid is developed to increase the reservoir permeability, enhance the reservoir energy and raise the temperature. The experiment analyzes the impact of autogenous nitrogen and catalyst ratio in the fracturing fluid on the reaction rates, gas production, and determines that the best autogenous nitrogen molar ratio is 2.5∶1, which is applicable to fracturing coal reservoir, the best quality concentration of autogenous nitrogen dosage is 8%~12% and the pH of reaction fluid is 4~5. This paper explores the impact of different temperatures on the reaction rate and gas production and analyzes the catalytic effect of different types of acid.
