The invention discloses a method for detecting leakage of a product oil pipeline. The method comprises the following steps of: acquiring instantaneous flow data and accumulated flow data detected by a mass flow meter, and detecting a negative pressure wave signal by a pressure sensor; judging whether the pipeline leaks or not according to the instantaneous flow data, the accumulated flow data and the negative pressure wave signals; and if leakage occurs, determining the leakage position of the pipeline according to the negative pressure wave signals. Whether the pipeline leaks or not can be judged in time according to the instantaneous flow data, the accumulated flow data and the negative pressure wave signals which are obtained in real time, meanwhile, the leakage position can be positioned according to the negative pressure wave signals, and whether the pipeline leaks or not is judged in combination with various data, so that the accuracy of pipeline leakage detection is improved. The invention further discloses a device for detecting leakage of the product oil pipeline a medium corresponding to the method, and the effects are as above.
Description
technical field [0001] The present application relates to the technical field of pipeline systems, in particular to a method, device and medium for detecting leakage of refined oil pipelines. Background technique [0002] Leakage is a major failure in the operation of oil pipelines. In recent years, oil pipelines have been perforated to steal oil and corroded and perforated to cause leakage accidents frequently, seriously affecting normal production and causing huge economic losses. At present, there are many methods for detecting pipeline leaks, but a single pipeline leak detection method cannot meet the timely detection of pipeline leaks and locate the leak location at the same time, and the accuracy of detecting pipeline leaks is not high. [0003] Therefore, how to timely judge pipeline leakage, locate the leakage point, and improve the accuracy of pipeline leakage detection is an urgent problem to be solved by those skilled in the art.
