ABSTRACT = {The actuator is a key component of the creaming tool in drilling applications. Its jet performances determine the
effective reaming efficiency. In this work, a new selective reaming tool is proposed and the RNG k-ε turbulence
model is used to calculate its internal and external flow fields. In particular, special attention is paid to the design
of the flushing nozzle. The results show that the jet originating from the flushing nozzle has a significant influence
on rock cutting and blade cooling effects. In turn, the jet performances depend on geometric structure of the
creaming actuator. In this framework, a conical-cylindrical nozzle with a diameter of 7 mm is initially considered
as a basis to implement a strategy to optimize the structural parameters of the reaming actuator, and improve the
related side tracking reconstruction technology.},
