摘要
The quaternary and tertiary strata of Pingshanhu mining area are water encounter unstable with serious clay invasion and high borehole expansion rate while drilling;and all these result in frequent drilling accidents and low drilling efficiency.The application test was made on non-dispersed low solid-phase drilling fluid system with polymer as main additives,clay invasion and shale hydration swelling were effectively inhibited.
