  1. INVESTIGATION of the TEMPERATURE EFFECTS on INTERPHACIAL TENSION in WATER SOLUTIONS of NEFTENOLS GF & K A.P. Losev Scientific superviser I.D. Bolotova

  2. Surfactants Neftenol К Neftenol GF

  3. Objects of research The Products ofJSC «Himeco-GANG» Neftenol GF – cation surfactant, drilling fluid component in primary tailing-in process, for blocking colmatage and removing bound water from the bedrock Neftenol K – surfactant for hydrochlorid-acid treatment of bottomhole formation zone

  4. Equipment Stalagmometer • Drops count method • Temperatures to 550C • The model of crude oil – rectified petroleum

  5. Equipment RefractometerIRF-454 B2М • Measurements of refractive index from 1,2 to 1,7 • Temreratures from 10 to 60 0C

  6. Concentration dependence of interphacial tension Neftenol GF solutions 300С Critical Micellium Concentration 500С Concentration, %

  7. Temperature dependence of interphacial tension Neftenol GF solutions Krafftpoint 0,25% 0,1% Temperature, 0С

  8. Temperature dependence of refractive index Neftenol GF solutions 0,1% 1% Temperature, 0С

  9. The Theory of solutions Refraction of ideal solution Increment of refraction

  10. Water r2=0.999 r2=1 Refractive indices of pure substances Neftenol GF

  11. Temperature dependence of refraction of 0.1% Neftenol GF solution Experimental curve Theoretical curve Temperature, 0С

  12. Increment of refraction of Neftenol GF solutions 0,25% 0,1% Temperature, 0С

  13. Phase diagram CMC Solution + micelles Solution Temperature, 0С Krafft point Solution + crystals Solubility Concentration, %

  14. Conclusions The new technique has been developed for investigation of temperature effects in solutions

  15. Conclusions The best values for practice application are ٧concentrations above 0,5% ٧temperatures only above 350С
