There are large formation dip, high building rate, slow drilling speed and long drilling cycle in Fangzheng area. The high-risk areas and formations of deviation were drawn to confirm easy deviation formation of BaoⅠsection and Xinwu group; by optimizing anti-deviation BHA and drilling parameters and combining with compound drilling and vertical drilling system, a set of anti-deviation and fast drilling technology in easily inclined formation of Fangzheng area was formed, which can improve drilling speed and shorten drilling time significantly.
