Abstract

The invention discloses an intelligent detection method, an intelligent detection device and an intelligent detection system. The method comprises the steps of receiving state information acquired by an oil well data acquisition platform, wherein the state information comprises oil pumping motor parameters acquired by a motor detection device in an oil well data acquisition system, loading data of an oil pumping rod acquired by a sensor in the oil well data acquisition system as well as displacement data of the oil pumping rod; determining a first indicator diagram according to the loading data of the oil pumping rod and the displacement data of the oil pumping rod; analyzing the first indicator diagram: if the first indicator diagram does not meet a preset standard, the sensor is detected to be damaged; if the first indicator diagram meets the preset standard, determining a second indicator diagram according to the oil pumping motor parameters and the displacement data of the oil pumping rod, comparing the first indicator diagram with the second indicator diagram to obtain a first error value, and if the first error is greater than a preset error value, the sensor is detected to be damaged. The damage of the sensor can be timely detected through analyzing the indicator diagrams.

Description

technical field [0001] The invention relates to the field of digital management of oilfield equipment, in particular to an intelligent detection method, device and detection system. Background technique [0002] With the development of technology, the application of displacement data, load data and other data collected by sensors to monitor the working conditions of oil wells has been realized. [0003] In practice, because the sensor is subjected to alternating loads for a long time, it is easy to be damaged, and the data collected by the damaged sensor has a large error, which affects the correct judgment of the working condition of the oil well. At present, most of the sensors are regularly inspected on site manually, and the damaged sensors are calibrated or replaced, so as to ensure the normal operation of the oilfield digital production management system. [0004] However, this method of manually checking the sensor on site regularly has poor timeliness. Contents of...
