Description

Technical Field

[0001] This utility model belongs to the field of oilfield development technology, specifically, it relates to a remote shutdown device for electric submersible pump wells. Background Technology

[0002] Currently, wellhead data in oilfields is monitored wirelessly, which improves oilfield production efficiency and reduces overall costs. However, there are still technical drawbacks in remote data monitoring and wellhead control. Electric submersible pump (ESP) wells are crucial equipment in oilfields for ensuring high and stable crude oil production, playing a vital role in increasing crude oil output. Currently, most ESP wells are manually inspected daily to measure and analyze production data. Due to the large number of wells and their wide distribution, this method results in extremely high manual labor intensity and affects the real-time nature and accuracy of equipment monitoring and production data. Furthermore, when ESP wells experience overload or underload due to abnormal current, manual intervention is often insufficient to stop the machine in time, posing a significant safety hazard and impacting safe production.
