Бурение грунтовых зондов, установка энергетических колодцев

The geometrical models that are used to represent the trajectory of the wellbore are:

2.3.1 Tangential Model

This model uses only the angles of inclination and direction measured at the lower survey station. The wellbore path is assumed to be tangential to these angles throughout the survey interval (Figure 3). The larger the angle, and the greater
the survey interval, the more inaccurate the results from this model. This model is highly inaccurate and is not recommended.
