<p>Hydrocarbon well probe comprises a main body (2) a downstream arm (3) and an upstream arm (5). At least one of the arms has a measuring device for determining the characteristics of fluid circulating in the well. The downstream and upstream arms are connected to the main body by first (A) and second (E) sliding pivot links, respectively. Preferred Features: The downstream arm (3) and the upstream arm (5) are connected respectively to a first end and a second end of a bearing pad (4) by a first (B) and a second (D) pivot link. The downstream and/or upstream arms (3, 5) comprise parallel plates connected by bridges. The axis of the main body (2) is eccentric with respect to the axis of the wells. The downstream and upstream arms (3, 5) are articulated with respect to the main body (2) in a locked position, where the arms (3, 5) are mounted inside the main body, and an open position, where the arms (3, 5) extend through the flow circulating in the well. The downstream and/or upstream arms (3, 5) are connected to a motor module (9) that controls their movements with respect to the main body (2). The motor module (9) can be deactivated, and both the motor module (9) and the downstream and/or upstream arms (3, 5) are dismountable. The upstream arm (5) comprises a device (6) for measuring the rate of fluid flow in the well.</p> |
