Patent ID: 11913292

Abstract:
A production logging tool (1) comprising an elongated cylindrical body (10) of longitudinal axis (XX′), the body (10) carrying an articulated dual arms deploying arrangement (12), at least one arm carrying at least one sensor (16, 16A, 16B) to analyze at least one property of a multiphase fluid mixture (MF) flowing in a hydrocarbon well (2), said sensor (16, 16A, 16B) extending along a sensor axis (SS′), the articulated dual arms deploying arrangement (12) comprising two deploying arms (13A, 13B) and a sliding sleeve (19), the deploying arms (13A, 13B) being operable from a retracted configuration into a vertically extended configuration, the deploying arms (13A, 13B) being coupled together through an outermost end hinge (17) at outermost ends of said deploying arms (13A, 13B), one arm (13A) being coupled to a first end part of the body through a first hinge (23A) at another deploying arm end, and the other arm (13B) being coupled to a second end part of the body through a sliding sleeve hinge (26) at the sliding sleeve (19) at another deploying arm end, wherein the articulated dual arms deploying arrangement (12) further comprises a pantographic mechanism (14) arranged such that the sensor axis (SS′) stays substantially parallel to the longitudinal axis (XX′) for any opening of the deploying arms (13A, 13B) from the retracted configuration to the vertically extended configuration.
