The Research on Drilling Technology Used for Strong Hole Shrinkage Borehole Condition in Borehole WFSD-4 of Wenchuan Earthquake Fault Scientific Drilling Project
Abstract:This article introduced technical problems encountered in drilling operation in strong hole shrinkage formation of WFSD-4 of Wenchuan earthquake fault scientific drilling project. On the basis of analyzing mechanisms of hole shrinkage and influence factors, drilling technical measures for resolving problems of strong hole shrinkage formation drilling were put forward. Good results were achieved in application of drilling technical measures for strong hole shrinkage formation in WFSD-4.
