| description | The invention discloses an early warning method and device for water breakthrough of an oil well, computing equipment and a computer storage medium, and relates to the technical field of oil reservoirdevelopment, the method comprises the following steps: obtaining oil well liquid production data, and searching a real minimum value and a real maximum value of the oil well liquid production data; Determining the occurrence frequency of abnormal signals, the minimum value of the abnormal signals and/or the maximum value of the abnormal signals of the oil well liquid production curve corresponding to the oil well liquid production data according to the real minimum value and the real maximum value; And judging whether the occurrence frequency of the abnormal signal, the minimum value of the abnormal signal and/or the maximum value of the abnormal signal meet the early warning condition of water breakthrough of the oil well or not, and if yes, performing early warning of water breakthroughof the oil well.
