  • Shale drilling is always faced with these problems such as borehole wall instability, high friction and drag and borehole cleaning etc. resulted from shales with developed beddings and fractures, and shale hydration. A hydrophobic nano SiO2 was selected as a plugging agent used to reduce water invasion into the fractures in shales, and hence to inhibit the shales from hydrating and swelling. The effects of different nano SiO2 on brine drilling fluids have been studied through laboratory experiments on regular mud property and SEM analyses. It was found that ① the hydrophobic SiO2 has strong hydrophobicity and adsorbability; the SiO2 powder can form a barrier to water invasion by adsorbing onto mud cakes, thereby effectively reduces the filtration rate. ② the solid hydrophobic SiO2 at 1%- 3%reduces the filter loss by 48.7%, while a hydrophobic SiO2 suspensions reduces the filter loss by 41.67%, but the solid hydrophobic SiO2 tends to agglomerate, thus losing the nano features.③ at 180℃, drilling fluid treated with 25%NaCl and 3%hydrophobic SiO2 suspensions has filter loss of 8.2 mL. At room temperature to 180℃, the water activity of drilling fluids treated with the hydrophobic SiO2 is 0.815 - 0.849, and the percent swelling of shale cores is about 4%, meaning that the SiO2 has strong inhibitive capacity. The coefficient of friction of drilling fluids treated with the hydrophobic SiO2 is 0.11 - 0.12, meaning the SiO2 treated drilling fluids have good lubricity. With all factors such as filter loss, stability and cost efficiency considered, a drilling fluid containing 3%hydrophobic SiO2 suspension and 25%NaCl is the optimum formulation.
