description The invention discloses a long-stoke chained oil pumping unit, which comprises a frame (6). A reversing mechanism (8) is arranged on the frame (6), two driven sprockets (5) and two driving sprockets (10) are arranged above and below the reversing mechanism (8) respectively, the driving sprockets (10) are connected with a motor (12), the driven sprockets (5) and the driving sprockets (10) are connected with each other through chains (9), a slider is fixed onto the chains (9) and horizontally movably arranged on the reversing mechanism (8) which is arranged between the two chains (9), and the slider is a bridging shaft(15) with two ends fixed onto different chains (9) and the middle penetrating through the reversing mechanism (8) and capable of horizontally moving on the reversing mechanism (8). An oil pumping rod of the oil pumping unit has long stoke, and the long-stoke chained oil pumping unit is compact in structure, high in reliability, energy-saving, low in manufacturing and operating cost and applicable
