water-based drilling fluid is usually the preferred drilling fluid. However
when it is used to shale
the problems of borehole instability
lost circulation
differential pipe sticking
and formation damage always may be caused. In order to solve these problems
nanoparticles are introduced into the water-based drilling fluid to obtain novel drilling fluid with improved properties. The present paper reviewed the water- based drilling fluid modified by nanoparticles. In terms of the type of the nanoparticles
the modified drilling fluid is divided into three types
organic nanoparticles
inorganic nanoparticles
and organic/inorganic nanoparticles modified drilling fluid. The three kinds of drilling fluid are discussed in detail. And the future developments of nanoparticles modified water-base drilling fluid are prospected.
