本文从泥浆流变性和钻井水力学角度出发,讨论了重泥浆影响机械钻速的因素,指出使用高比重的加重材料和加强机械净化是使用重泥浆井段提高机械钻速的可循途径。
In this paper, we discuss the factors that affect the penetration rate of heavy mud from the perspective of mud rheology and drilling hydraulics, and point out that the use of heavier materials with higher specific gravity and enhanced mechanical purification are the ways to improve ROP with heavy mud wells.
