汶川地震断裂带科学钻探项目WFSD-4孔套管护壁技术
Wall Casing Protection Technology In WFSD-4 of Wenchuan Earthquake Fault Scientific Drilling Project
摘要
Abstract
Borehole wall protection is one of the key technologies for resolving drilling problems in Complex Strata.This pa-per introduces some special casing adopted in the drilling operation of the borehole WFSD-4, including large diameter cas-ing technology in small clearance condition, retrievable casing technology for small diameter core drilling in existing large borehole and two phase casing and cementing technology used in strong borehole shrinkage section.关键词
