Axial motion, or bit bounce, has a characteristic frequency whose value is a function primarily of the type of bit, mass of the BHA, drillstring stiffness and formation hardness.
Web26 de jun. de 2015 · The most common deviation tools for directional drilling are steerable motor assemblies (or so-called positive-displacement motors [PDMs]) and rotary steerable systems (RSSs). Adjustable-gauge stabilizers, known as “2D rotary systems,” have become quite popular to run with the rotary and PDM assemblies to control inclination.
