Description

Technical Field

[0002] Dogleg refers to the angle at which the direction of the wellbore changes from one point to another in the wellbore. Dogleg: The angle at which the direction of the wellbore changes from one point to another in the wellbore. This angle reflects both the change in the well inclination angle and the change in the azimuth angle, and is usually called the full-angle change rate or the wellbore curvature. A large full-angle change rate of the well will increase the difficulty of drilling and oil production operations and easily lead to downhole accidents. The bending of the pipe rod caused by the full-angle change rate of the wellbore reduces the degree of freedom of the pipe rod, which will cause concentrated release of stress, causing the fixed valve to open during the downstroke, resulting in leakage and reducing pump efficiency.
