Recently, the region of Winsor II has been used to treat produced water to decrease heavy metals amount and oils and greases contents (OGC). However, it usually demands high temperature, and the interaction effect of the process factors have not yet been investigated. This study has the objective of treating synthetic and real produced water using the region of Winsor IV (microemulsions) to reduce the oil and grease content and also the salinity. Besides, we also statistically investigated the effect of temperature, time, and microemulsion amount. Synthetic produced water (SPW) treatment was studied through the experimental design with combinations for three variables: time (30–90 min), temperature (25–45 °C), and microemulsion percentage (10–50%). The conditions established for the treatment of real produced water (RPW) were: 30 min, 35 °C, and 50 % of the microemulsion. It was observed that on the treatment of SPW, the OGC reduction ranged from 69.98 % to 97.98 % and the salinity from 18.74 % to 34.66 %. Regarding the treatment of RPW, the OGC reduction was 86.23 %, from 146.56 mg.L⁻¹ to 20.18 mg.L⁻¹, and the reduction of salinity was 11.86 %, from 35,090.20 mg.L⁻¹ to 30,928.50 mg.L⁻¹. We concluded that the treatments of SPW and RPW using microemulsion to reduce OGC and salinity were efficient.

最近，Winsor II地区已用于处理采出水以减少重金属含量和油脂含量（OGC）。但是，它通常需要高温，并且尚未研究工艺因素的相互作用。这项研究的目的是使用Winsor IV（微乳液）区域处理合成水和实际采出水，以减少油脂含量以及盐度。此外，我们还对温度，时间和微乳液量的影响进行了统计研究。通过实验设计研究了合成采出水（SPW）处理，并结合了三个变量：时间（30–90分钟），温度（25–45°C）和微乳液百分比（10–50％）。建立的用于处理实际采出水（RPW）的条件为：30分钟，35°C，和50％的微乳液。观察到，在处理SPW时，OGC的降低范围为69.98％至97.98％，盐度为18.74％至34.66％。关于RPW的治疗，OGC的减少量为146.56 mg.L，为86.23％^-1至20.18 mg.L ^-1，盐度降低从35,090.20 mg.L ^-1降至30,928.50 mg.L ^-1为11.86％。我们得出的结论是，使用微乳剂减少SPC和RPW可以降低OGC和盐度。
