矿渣对钻井液流变性能的影响研究

Multifunctional drilling fluid is used in the site because of its suitable drilling performance and can realize the fine cementation of second interfaces.Slag shows chemically inert in non-alkaline environment,whether slag will affect on rheology,which is one of the most important drilling fluid properties. So the study examined the slag under different temperatures and densities in order to research the rheology changes.It is shown by the research results that more slag and higher density increasing the drilling fluid solid content ,it makes plastic viscosity and yield point increasing.Increasing temperature also makes plastic viscosity and yield point higher because it increases the number of active solid particles.
