Effect of Nano Oxide Particles Addition on Lubricating Properties of Water-based Drilling Fluid
摘要
Abstract
This study has tried to improve lubricating properties of water-based drilling fluid with adding nano oxide parti-cles to it.Alumina ( Al2 O3 ) , titania ( TiO2 ) and silica ( SiO2 ) nanoparticles were selected as modified drilling fluid addi-tives, the study was made on the effects of adding different kinds and concentrations of oxide nanoparticles on lubricating properties and friction reducing of water-based drilling fluid by using the extreme pressure lubrication device and the pin-on-disk friction and wear tester.The results show that the three kinds of spherical nanoparticles all have the effect of lubrica-tion and antifriction, but the drilling fluid containing SiO2 particles has the best properties of lubrication, filtration and anti-friction.When the adding amount of SiO2 nanoparticles was 0.4%, the filtration was minimum, the reduction rates of lubri-cating and friction coefficients were 15.6%and 32.0%respectively with smooth wear scar, the friction reducing effects was the most evident.When the concentration of the nanoparticles was higher than 0.5%, the friction reducing effect decreased with obvious delamination and wear.关键词
