The utility model relates to a motor pusher for a pumping well in an oil field, comprising a hydraulic jack (1), an auxiliary eject rod (2), a jack thread base (3), a jack thread (4), a high-pressure rubber tube (5), a manual hydraulic pump (6) and a handle (7). The motor pusher is characterized in that the hydraulic jack (1) of the motor pusher is a single-acting mode and is connected with the manual hydraulic pump (6) by the high-pressure rubber tube (5); the manual hydraulic pump (6) is provided with the handle (7); the hydraulic jack (1) props against the auxiliary eject rod (2) which is positioned at the lower part of the hydraulic jack (1); and the jack thread (4) integrated with the auxiliary eject rod (2) is connected with the jack thread base (3) by threads and can be adjusted. The motor pusher has simple structure and convenient operation, saves time and labor, reduces the labor strength of post workers, improves the working efficiency, increases the yield of crude oil and avoids from causing sand blocking and well laying due to replacement of the motor of the pumping well with serious sand generation.
