Research on the influence factors of hydraulic oscillator on drag reduction efficiency in horizontal well drilling

Measurement + Control
The application of hydraulic oscillator can solve the problems of large friction and serious pressure support in the drilling process of extended reach well and long horizontal well, but the conventional hydraulic oscillator parameter setting is not ...

Further investigation on LuGre friction force model under normal load variations

, 2021
A large number of friction force models has been proposed in the literature to include the different properties and represent the frictional behavior with more detail [1, 2]. Generally, the friction models are divided into two groups, i.e., the static and dynamic models.
