Research on wellbore stability technology for coalbed methane development in the Ordos Basin
This article delves into the key technical issue in the development of coalbed methane in the Ordos Basin-wellbore stability.By analyzing the special geological conditions of the basin,the complexity of stress distribution,and the changes in coal seam structure and physical properties,this article emphasizes the core role of drilling fluid in wellbore stability,especially the reasonable density selection,sealing and inhibition evaluation and optimization of drilling fluid are key factors to ensure wellbore stability and improve development efficiency.
