MMH钻井液在南方海相碳酸盐岩地层中的应用

Applications of MMH Drilling Fluid in Carbonate Formation of South Marine Faces

针对南方海相碳酸盐地层岩石可钻性差 ,泥岩、砂岩、白云岩、碳酸盐岩交互 ,岩性变化大等特点 ,在室内试验的基础上 ,优选了 MMH钻井液体系。在秧 1井中的应用表明 ,该钻井液体系能满足海相碳酸盐岩地层钻井要求 ,且能提高机械钻速 ,减少井下事故的发生。

Based on lab tests, the MMH mud is optimized for drilling in carbonate formation of south marine faces, which has a series of behaviors, such as poor drillability, lithological, inhomogeneity and great lithologic variation. Applications in Yang 1 well shows this mud can be applied in drilling in carbonate formation of marine faces with improved penetration rate and reduced downhole emergency.
