Abstract
Deep drilling requires addressing various challenges in complex formations,including borehole wall instabilities such as lost circulation,water influx,formation crushing,collapse,borehole shrinkage,and borehole enlargement.To meet the demands of deep exploration drilling and enhance drilling efficiency and quality,the rational design and application of drilling mud systems are essential.Through field practice,we systematically studied mud system design and application,identified optimal mud formulations,resolved key issues in deep exploration drilling,and achieved stable borehole walls without collapse,enabling rapid and efficient drilling operations.关键词
