The water injection in the mining technology of an oil field of Jiangsu Province, Sinopecis driven by a 6KV / 630KW motor, the water injection rate in each block of the oil field needs to be adjusted according to the mining conditions, the company uses a return valve to control the flow, which has caused serious energy waste and brought other problems, such as serious equipment wear and tear, low control accuracy.
1. Water injection pump is the big consumers of electric energy in oil industry, with obvious energy saving effect after frequency control.
2. Achieve soft start, without impact on the power grid.
3. Small equipment wear and tear, extended service life of the equipment, reduced the maintenance workload.
4. The control parameters of process parameters are greatly improved, and the system is always running at the optimum process point.
5. Improve the degree of automation and oil extraction efficiency.
