Abstract
A computer-implemented method for detecting an oil leak in a beam pump, wherein, during pumping movement of the rod linkage through the wellhead, a stroke region is formed, the method including a) capturing images of an image sequence containing at least the stroke region of the rod linkage, b) detecting soiling in the stroke region of the rod linkage in comparison with a known clean state for an image in question of the image sequence, c) ascertaining the position of the detected soiling for an image in question of the image sequence by the associated position of the rod linkage, d) determining the change in the soiling at the ascertained position over at least one pumping cycle from the images of the image sequence, e) checking if the change in the soiling exceeds a predefined limit value, and if applicable, outputting a warning of an oil leak.
