Problems solved by technology

[0004] However, there will be multiple consecutive dynamometer diagrams of the pumping well every day. For example, one dynamometer diagram of the pumping well may be generated every 20 minutes, and there will be about 70 dynamometer diagrams per day. Every time a fault is diagnosed from the dynamometer diagram, an alarm message will be generated, which is prone to false alarms and false alarms
And as long as the failure of the pumping well is not recovered, the automatic monitoring system will continuously send alarm information based on the dynamometer diagram. Since there are many pumping wells in the oil field, the amount of alarm information that needs to be processed every day is relatively large, so some false alarms And misreported alarm information will be mixed with a large number of normal alarm information, resulting in some important alarm information not being processed in time

Abstract

The invention discloses a fault alarm method and device. According to the method, after an indicator diagram of an oil pumping well is obtained, if the situation that a fault exists in the oil pumpingwell is analyzed based on the indicator diagram of the oil pumping well, information of the fault is recorded; and when the fault is analyzed from a continuous preset number of pieces of the indicator diagrams of the oil pumping well, alarm information that the fault exists in the oil pumping well is output. The scheme of the method and device can reduce the false alarm rate of the fault and improve the accuracy of fault alarm.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis and alarm, in particular to a fault alarm method and device. Background technique [0002] Pumping wells is a commonly used method in oilfield development at present. Therefore, timely diagnosis and discovery of failures in pumping wells is related to the overall economic interests of the oilfield. [0003] In order to diagnose the failure of the pumping unit, sensors (such as displacement and load sensors) will be installed on the pumping unit, and according to the displacement data and load data of the pumping unit collected by the sensor, an indicator for analyzing the failure of the pumping unit can be generated In this way, when the automatic monitoring system of the pumping well diagnoses that there is a fault in the pumping well based on the dynamometer diagram, it outputs an alarm message. [0004] However, there will be multiple consecutive dynamometer diagrams of the pumping wel...
