n: A kind of computational method of directional well. It is used widely because it is simple and precise.

n: A new development of designing for section of directional well. This section can improve well status of directional well obviously.

n: A kind of deflecting tool for drilling directional well.

n: A style of well profile of directional well. Its kick off point is far away from well head and its deflecting angle is bigger.

n: Directional well drilling at the section above 4000m. It is harder than other kinds of directional drilling due to small hole diameter, high pressurem high temperature and bigger friction between drill string and borehole face.

n: A kind of cone bit with no offset, opened outer teeth guidance. Used for drilling vertical well and directional well.

n: Abbreviation of basic element of directional well ,including diviation angle,drift azimuth and well depth.

n: Technical specialist who is good at directional well drilling and takes charge in the techologic works of directional well drilling.

n: Refer to directional hole,please!

n: The dimensional position which the wellbore of directional well passes from the well head to bottom.
