摘要
介绍了汶川地震断裂带科学钻探WFSD-1孔在破碎和严重缩径的断层泥地层采用的小间隙固井工艺,以及利用试下套管测定的泥浆循环压力降,结合泥浆泵最高承受压力确定固井工艺参数的方法。
This article discussed the small annulus cementing technology, which was used for the hole of WFSD - 1 of Wenchuan earthquake fault scientific drilling project in broken formation and fault gouge tight hole and introduced how to determine cementing parameters by combining the mud circulation pressure drop during test casing with the maximum bearing pressure of mud pump.
