▎ 摘　　要

NOVELTY - Application of high-nitrogen heterographene nanosheet in oil-based drilling fluid, is claimed. The high nitrogen heterographene nanosheet is added to the oil-based drilling fluid. The content of nitrogen atoms on the surface of the whole material of the high nitrogen heterographene nanosheet is 3.5-8%. USE - Application of high-nitrogen heterographene nanosheet in oil-based drilling fluid e.g. white oil-based drilling fluid (claimed) for oil and gas field.
