GLYCERIN AND SAPONIFIED COCONUT OIL (ION TENSIONANT) AS A MOVING FLUID FOR INCREASED OIL RECOVERY

摘要

Glycerine and saponified coconut oil (ionic tensoate) as displaced fluid for increased oil recovery. The present invention refers to the development and development of an oil displacement fluid composed of glycerin and coac oil saponified OCS (coationic tenive),Referred to here as glycerin -based displaced fluid (fdg),With application in the processes of injection of fluids for recovery of oil. With the displacement fluid developed from the present invention employed with the objectives of reducing the interfacial tensions in the pores of the reservoir rock and achieving a miscible displacement with good displacement sweep efficiencies, optimizing the advanced recovery of Petr o Leo. The fluid displacement of the present invention showed satisfactory behaviour as to its reology, in which its viscosity was similar to that of the petroleum tested, by the presence of glycerin, at the mean well temperature (55 OC),This results in good mobility reasons and good recovery factors, between 30% and 60%. The displaced fluid of the present invention also presented stability before: temperature variation, in the range of up to 100C, with few degradation losses, in the case less than 4% in mass of FDG; saline conditions, supporting up to a maximum of 3%in salt mass, without losing The chemical and physical properties.
