Oil Pumpjack Illustration - Visual Representation of Petroleum Extraction #3686120 (License: Personal Use)

This monochrome vector illustration shows a classic beam-type oil pumpjack (nodding donkey) in mid-cycle, with the walking beam pivoted on a central支架 and a large gray counterweight balancing the reciprocating motion. The black structural components contrast sharply against the white background, emphasizing form and function over realism. The image captures the rhythmic up-and-down action used to extract crude oil from underground reservoirs.
