The invention discloses an oil well short-term production index abnormity early warning method. The problems of large data amount and poor early warning timeliness of an early warning method with high accuracy in the prior art are solved. The method provided by the invention comprises the steps that the production data of production indexes of an oil well in a period of time are collected; the average value of oil well production indexes in the period of time is calculated; the standard deviation sigma of the oil well production indexes in the period of time is calculated; an production index abnormity degree A is calculated; and the early warning level is determined according to the specific value of the index abnormity degree A. The oil well short-term production index abnormity early warning method provided by the invention has the advantages of high early warning timeliness, high accuracy, simple operation and the like.
