Abstract

Summary

It’s clearly obvious that a technology alone cannot act as a panacea, but thermochemical treatment method can act as a multifunctional technique. This method is based on the decomposition reaction of ammonium nitrate. This work is planned to find study the thermobaric effect of thermochemical fluid, determine its effect on petrophysical parameters of formation and rheological aspects of oil. To measure the released pressure and temperature, 5 ml of the thermochemical fluid was injected into the reaction cell and these parameters were registered in real time regime. It was found that pressure and temperature in reaction zone increase up to 80 atm and 230 ? respectively. Experiments on core plugs show that after thermochemical fluid a network of fractures occurs. Rheological tests show that because of reaction products oil viscosity reduces from from 630 to 55 m.Pa.s.
