The method of directional well on sales space position and shape of wellbore is to measure the wellbore. Each measurement point has three data, namely sounding, well inclination, and well inclination azimuth. We call these three measurement data as well. basic elements of the body.
1. Sounding: The length of the wellbore from any point on the axis of the wellbore to the wellhead is called the sounding at this point, and is also called the measured inclination depth at this point. Usually represented by the letter L, and its unit of measurement is meters or feet.
2. Well inclination angle: the angle between the wellbore direction line (tangent line) at the well logging point of directional well on sales and the gravity line passing through this point is called the well inclination angle at this point. Both the borehole direction line and the gravity line are directed straight lines.
3. Well inclination azimuth: take the true north line as the starting edge, and rotate clockwise to the angle that the well inclination azimuth turns. It can also be expressed by quadratic value, which refers to the angle between it and the positive bearing line or the due south bit line. The quadrant value varies between 0-90°, and the quadrant should be marked.
