MODIFIED CARBON BLACK FOR OILFIELD FLUIDS |
摘要 |
Surface treated modified carbon black particles and oil-based drilling fluids are described. The carbon blacks are incorporated into the oil-based drilling fluids to reduce the electrical resistivity of the oil-based drilling fluids. The surface treated carbon blacks can include a hydrophobic organic group and are readily dispersible in oil-based drilling fluids. |
