摘要

The present invention relates to the drilling operations of underground, and relate more specifically to drilling fluid, the hole that can be used for digging a well in a subsurface formations, can show improved shale inhibition and method, such drilling fluid is used in subterranean formations. An embodiment of the method for the invention provide it is a kind of for dig a well hole in a subsurface formations of method include that provide include a drilling fluid containing water-based fluid and the shale inhibiting component including a nanoparticle sources; Drilling fluid is placed in wellbore in subsurface formations. Another embodiment of the present invention provides a kind of method for flocculation comprising provides the fluid including suspended particles, being added to the fluid including suspended particles includes a shale inhibiting component of a nanoparticle sources to form flocculated particle.
