Method of tertiary oil recovery |
| abstract |
The invention relates to the field of the oil industry and makes it possible to increase the efficiency of the method of tretining oil production using a stimulating agent. . , ether sulfonates. As a stimulating agent, aqueous solutions are used that contain 0.1–3.0 wt.% Of triisobutylphenol sulfonate (TIBPS) of the general formula (OCH2CH2V-S03n 9 where X 4-12; M is Na or K, or N11.. TIBPS is surface active substance (surfactant) that is stable over a wide range of temperatures and pH values.Aqueous TIBPS solutions increase the surface tension at the surfactant phase boundary / air by a value of POIR of about 25-30 mNm and the surface tension of an oil / surfactant solution by 1 -10 (by Di Nony). Based on the activity and stability of TIBFS suitable for alkaline and acid deleterious metal cleaning process. In various salt-prefecture Content |
