Anti-leakage Cementing Technology with Low Density Slurry in WFSD-2 of Wenchuan Earthquake Fault Scien-tific Drilling Project
摘要
Abstract
Due to the broken stratum, wall collapsing, landslide accidents and lost circulation happened frequently in the drilling of the second hole of Wenchuan earthquake fault scientific drilling project (WFSD-2).For preventing lost circu-lation during cementing, anti-leakage cementing technology with low density slurry was selected.Through multiple perform-ance experiment of slurry, the formulation of low density slurry for anti-leak was optimized.This formulation was successful-ly adopted to cement theø168.3 casing in WFSD-2.关键词
