Abstract:The WFSD-3 hole is one of the series of boreholes of Wenchuan earthquake fault scientific drilling project. During 2 years’ construction, many technical challenges, such as drilling in complex strata, large diameter undisturbed core sampling and borehole wall protecting under high geo-stress were overcome. This article especially focused on the construction technology and experience of the WFSD-3 hole and discussed some technical problems. |
