CY-1钻孔盐水泥浆护壁技术

Wall Protection Technology with Saltwater Mud in Borehole CY-1

摘要:

CY-1钻孔是河北沧县盐矿深部勘探的第一钻，在钻探施工中，泥浆护壁是遇到的技术难题之一。针对工区施工条件采用了分段泥浆转换方案，确保了施工安全及质量。实践表明，该钻孔泥浆护壁方法技术路线可行，实现了顺利取心，为沧州地区深部盐矿勘探积累了经验。详细介绍了该孔盐水泥浆护壁技术。

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.
