The utility model provides a crude oil pumping test multi-parameter oil nozzle which enables parameters of the oil nozzle to be conveniently adjusted and improves the work efficiency. The crude oil pumping test multi-parameter oil nozzle comprises an oil nozzle body and an oil nozzle sleeve. A spring pin fixing hole and at least two oil outlets with different diameters are formed in the oil nozzle body. The oil nozzle body is installed in the oil nozzle sleeve and locked through a spring pin. In the production period of an offshore production platform, the pumping test and parameter adjustment of the crude oil are achieved under the condition that a new well double-wing process is not started. Particularly, in the acidization process of a new offshore oil well, acid liquid can be discharged to an acidization ship pollution liquid tank without the crude oil outward conveying process. The crude oil pumping test multi-parameter oil nozzle can be applied to an earlier period of new well production. The parameters
