The advantages of water well drilling rigs
1. Based on the concepts of oblique shear index, anisotropy index and comprehensive cutting preparation anisotropy index of drilling machine bit, the general agricultural formula and simplified form of formation natural deflecting force suitable for the actual bit, volume crushing and surface crushing of drilling machine are derived; The calculation formulas of formation variable merging oblique force and formation variable azimuth force in directional drilling are derived by using the drilling machine WOB cone method, which provides the analysis basis of formation force quota for directional and orbit control of drilling machine. It is verified that the theoretical analysis results are in good agreement with the drilling practice.
2, The formation with small orientation is the flapping force and formation variable positioning force, spoon well inclination angle, WOB, formation dip angle, drilling machine bit anisotropy index, formation anisotropy index, borewell azimuth and formation up dip azimuth force, which may also be the reduced azimuth force. In general, the formation variable deviation force makes the drill bit trajectory of the drilling machine close to the formation normal direction, and the formation variable azimuth force makes the well bore orientation close to the formation inclined direction. When the well bore orientation of the drilling machine is consistent with the formation dip orientation, the formation azimuth changing force is zero.
3, Based on the new concept, the critical formation dip equation is found out, which provides a preliminary quantitative explanation for judging the bit trend of drilling machine.
The formation force of the drilling machine is directly proportional to the WOB. Increasing the WOB will significantly increase the formation force
