    Abstract:

    In the complicated formation, 2 drill strings were broken in the hole WFSD-1 and 2 fishers were lost in it. Directional drilling was conducted to pass by the accident drilling tools. LZ-89 continuous whipstock was used for sidetracking at the bottom of the cement hole with the depth of 580.07m. A new hole was generated after 3m directional drilling in more than 3 hours. The paper introduced technical points of the directional drilling (sidetracking).
