| 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 con- struction technology and experience of the WFSD -3 hole and discussed some technical problems. |
