Conventional experience reveals that it is often impossible to employ usual fluid additives for some special functions because of suitable physical, mechanical, chemical,thermal and environmental characteristic. Therefore, the science and research centers are searching for a physically small, chemically and thermally stable, biologicallydegradable, or natural product to improve water base drilling fluid properties to apply in most parts of oil and gas exploration.Thank to nano technology, carbon nano tubes were proved enhanced physio-chemical, electrical, thermal, hydrodynamic properties and interaction potential in compare with other materials. This paper investigates the effect of different amount of multiwall carbon nano tubes in water base drilling fluid onrheological properties and hole cleaning capacity. Laboratory tests showed that carbon nanotubes play an important role in improving rheological properties and increasing cleaning efficiency of the mud.
