Intelligent Operation and Maintenance of Pumping Units

 Intelligent Operation and Maintenance of Pumping Units

In the battle to stabilize production in the heavy oil block, the efficiency of the pumping unit is improved throughout the entire process. The company strictly implements the "one well, one policy" management standard, equips the pumping unit with variable frequency speed control devices for high water content wells, and installs the pumping unit bare rod automatic cleaning system for the well group with serious wax deposition. Especially in the S48 block, through the implementation of "pumping unit health grade management", 32 old pumping units that have been in service for more than 8 years are included in the key transformation plan, and magnetic levitation motors are used to replace the traditional drive system, and the daily power saving of a single unit reaches 85 kWh.

In terms of intelligent operation and maintenance of pumping unitsPumping Unit, the company has built an Internet of Things platform covering 236 pumping units, and collects 12 key parameters such as indicator diagrams and load curves in real time. Through the "digital twin + expert diagnosis" mode, the operation and maintenance team successfully compressed the downtime of pumping unit failures to 4.2 hours/unit/year, which is 37% lower than the industry average. At present, the SVES team is accelerating the testing and application of the AI early warning system for oil pumps, and plans to achieve intelligent prediction and autonomous optimization of the operating status of oil pumps in the entire well field in the second quarter.
