RESUMO:

The use of drilling fluids ensures greater efficiency of oil drilling, as they perform a number of functions and are capable of profoundly influencing this process. The different types of drilling fluids and their applicability cause constant studies on their formulation. Thus, microemulsion systems (SME's) have been evaluated as a good proposal among the additives used in the formulation of these fluids. This work aimed to develop drilling fluids using microemulsions (ME's) oil in water, as well as to analyze their properties compared to the literature. For this, several SMEs were initially tested in order to find the one that presented a good ME region oil in water to prepare the fluid. The system found was composed of tap water and glycerin in the aqueous phase, Alkonat 70 nonionic surfactant and paraffin or olefin as the organic phase. From these systems, an experimental design was elaborated to evaluate the influence of the percentage of glycerin in the aqueous phase and the NaCl concentration in the properties of the drilling fluid, finding. an optimized fluid whose characterization was made later. The results showed that microemulsion fluids presented as an excellent alternative for drilling fluids, considering that their rheological properties were considered satisfactory even after the aging of the fluids, in addition to presenting very low filtration volumes.
