The present invention relates to a well tool 1 adapted to be centralized in a well. The well tool includes an angle orienting feature, for orienting the well tool 1, 50 around a longitudinal axis of the well tool. The well tool includes at least three wheels 3, 53 each adapted to define a wheel contact point. Each wheel extends from a longitudinal well tool body 6, 56 and is adapted to contact a well inner wall. The well tool 1 includes a swivel 28 adapted to allow the well tool to be attached to a longitudinal element 29 and to allow the longitudinal element 29 to rotate in relation to the well tool. The angle orienting feature is adapted to orient the at least three wheels 3, 53 extending from the well tool body 6, 56 away from a lower portion of the well inner wall 44 when the well is inclined or horizontal.
A well tool (1) adapted to be centralized in a well, the well tool comprising an angle orienting feature, for orienting the well tool (1, 50) around a longitudinal axis of the well tool, the well tool including at least three wheels (3, 53) each adapted to define a wheel contact point and wherein each wheel extends from a longitudinal well tool body (6, 56) configured to be centralized in the well, and wherein each wheel is adapted to contact a well inner wall (44), wherein the well tool (1) includes a swivel (28) adapted to allow the well tool to be attached to a longitudinal element (29) and to allow the longitudinal element (29) to rotate in relation to the well tool (1), whereby the angle orienting feature is configured to orient the at least three wheels (3, 53) extending from the well tool body (6, 56) away from a lower portion of the well inner wall (44) when the tool is deployed in an inclined or horizontal well, wherein the angle orienting feature is provided by a centre of gravity (47) of a wheeled portion of the well tool (1, 50) offset from, and below a center of the well tool (1) when the well tool (1, 50) is in a horizontal or close to horizontal operating position, and wherein the at least three wheels (3, 53) are located in the wheeled portion (25) of the well tool (1), the well tool (1) further including a second portion (26) adapted to be attached to the wheeled portion (25) and the swivel (28), and wherein the offset center of gravity (47) of the well tool (1, 50) is provided by an orienting element (27) between the wheeled portion and the second portion (26), whereby the wheeled portion (25), the interconnection piece (22) and the second portion (26) are adapted to form a ramp step shaped well tool.
