1 Introduction
In oilfield development, maintaining formation pressure through water injection is a crucial means of achieving high and stable crude oil production. Especially as oilfields enter the mid-to-late stages of development, it is necessary to continuously increase the water injection volume to maintain formation pressure and ensure stable production. Statistics show that in 1997, the total electricity consumption for water injection in all oilfields was 6.17 billion kWh, and the electricity consumption for long-distance pipelines was 1.251 billion kWh. The overall water cut in all oilfields nationwide had reached 80.4%, and the electricity consumption for water injection increased year by year. Due to changes in downhole geological conditions, well washing, and insufficient water supply, the water injection volume varies at different development stages, resulting in significant fluctuations in daily water injection volume. To adapt to these changes, without speed control measures, the flow rate can only be controlled by adjusting the number of pumps in operation and manually adjusting valves, thereby adjusting the water injection volume. This inevitably creates a large pressure difference between pump pressure and pipeline pressure, increasing the energy consumption of the water injection system.
