A guiding sub-section (2) of a production logging tool (1) comprises a central rigid stem (30) having a first mechanical connector (33) at one end and a second mechanical connector (34) at an another end, and carrying a roller deploying arrangement (31) comprising multiple external articulated arms (35A, 35B, 35C) circumferentially distributed about said body, each articulated arm comprising a roller assembly (32A, 32B, 32C) adapted for contact with a wall (7) of the hydrocarbon well (4) and operable from a retracted configuration into a radially extended configuration. The roller assembly (32A, 32B, 32C) comprises an arm hinge (51) coupling a first arm part and a second arm part of each articulated arm (35A, 35B and 35C) and having an arm hinge axis (AA′) substantially perpendicular to the longitudinal axis (XX′), a roller bearing (52) secured onto the arm hinge (51) and having a roller axis (BB′) angled with respect to the hinge axis (AA′), and an anti-slippage friction roller (53) received onto the roller bearing (52) in a rotation free manner.
