    Abstract:

    In drilling construction of borehole CY-1 in a salt mine of Hebei, wall protection by mud was a technical difficulty. According to the different construction conditions, sublevel mud scheme was adopted to ensure construction safety and quality. The practice shows that this wall protection technology is feasible. The paper introduces the wall protection technology with saltwater mud in borehole CY-1.
