Abstract: During production of complicated and craven faulted oilfields, the directional drilling technology with bibuild and bihold profile is used to prevent the hits of cluster wells. This paper presents design and its features, wellbore control and safety measures of the directional well with bibuild and bihold profile in the C3 faulted block. The technology will have certain value for reference to the production of other complicated and craven faulted oilfields.
