The conventional configurations of the Internet of Things (IoT) related to pumping wells include an electric parameter indicator and dynamometer. If working-condition diagnosis and virtual production metering of well pumping can be realized through electrical parameters, the need for dynamometers can be eliminated or reduced, with a potentially major effect on reducing investment and improving coverage of the IoT in oil wells. In the complete paper, an integrated multimodel diagnosis method is proposed. The diagnostic and virtual-production-metering method and software based on electrical parameters have been applied in many of the operator’s oil fields.
Introduction
In China, more than 90% of the more than 400,000 oil wells are sucker-rod-pump (SRP) wells.
