Center Contents: Causes of drilling bending; Anti-inclined; Governance oblique; Directional drilling; The future direction of this subject. During the drilling process, the change of the top and the azimuth of the drilling hole causes the change of the position of the drilling space, which is called the bending of the drilling hole. During the drilling, various methods and measures are taken to control the variation of the top and the azimuth of the borehole so as to make the borehole bend in conformity with the geological contents of the center. The reasons for the bending of the borehole; Anti-tilting; Governing slant; Directional drilling The future direction of the subject. During the drilling process, the change of the top and the azimuth of the drilling hole causes the change of the position of the drilling space, which is called the bending of the drilling hole. During drilling, various methods and measures are taken to control the variation of the top and the azimuth angles of the borehole, so that the borehole bend conforms to the geological setting
