专利汇可以提供Aromaticity influencing the thermostability of micellar dispersions专利检索,专利查询,专利分析的服务。并且An improved process of recovering hydrocarbon from a hydrocarbon-bearing subterranean formation wherein a micellar dispersion comprised a hydrocarbon, surfactant and aqueous medium is injected into and displaced through the formation to recover hydrocarbon through a production means, the improvement comprising determining the temperature of the formation, mixing with the surfactant and aqueous medium a hydrocarbon having sufficient aromaticity to obtain a stable micellar dispersion at the temperature of the formation. The micellar dispersion can optionally contain cosurfactant and/or electrolyte. Such a process is especially useful to recover crude oil in a secondary or tertiary oil recovery process wherein the formation is at a temperature in excess of ambient temperature.,下面是Aromaticity influencing the thermostability of micellar dispersions专利的具体信息内容。

  • 2. The process of claim 1 wherein the temperature of the formation is in excess of about 80* F.
  • 3. The process of claim 1 wherein the temperature of the formation is in excess of about 150* F.
  • 4. The process of claim 1 wherein the temperature of the formation is in excess of about 200* F.
  • 5. The process of claim 1 wherein the micellar dispersion contains cosurfactant
  • 6. The process of claim 1 wherein the micellar dispersion contains electrolyte.
  • 7. The process of claim 1 wherein the surfactant is a petroleum sulfonate.
  • 8. A method of increasing the thermostability range of a micellar dispersion comprised of hydrocarbon, aqueous medium, and surfactant to higher temperature ranges, the method comprising mixing with the aqueous medium and surfactant a hydrocarbon having an aromaticity sufficient to obtain a stable micellar dispersion at a higher temperature.
  • 9. The method of claim 8 wherein the micellar dispersion contains cosurfactant.
  • 10. The method of claim 9 wherein the cosurfactant is alcohol containing from one to about 20 carbon atoms.
  • 11. The method of claim 8 wherein the surfactant is a petroleum sulfonate having an average equivalent weight within the range of from about 360 to about 520.
  • 12. The method of claim 8 wherein the micellar dispersion is stable at temperatures in excess of about 80* F.
  • 13. The method of claim 8 wherein the micellar dispersion is stable at temperatures in excess of about 50* F.
  • 14. The process of claim 8 wherein the micellar dispersion is stable at temperatures in excess of about 200* F.
  • 15. The method of claim 8 wherein the micellar dispersion contains electrolyte.
