Description

technical field [0001] The invention belongs to the field of pressurized water injection pumps, and relates to pressurized water injection of oil field water injection wells, in particular to a pressurized water injection device for repressurized energy-saving water injection of oil field water injection wells. Background technique [0002] Water injection is one of the measures commonly used in oilfields to increase production. The pumping stations commonly used in major oilfields supply high-pressure water in a concentrated manner, and the high-pressure water is transported to each injection well through the pipeline network, and then through the water distribution manifold or the throttle valve and water meter at the wellhead to adjust each The water injection volume of each well meets the injection requirement. Due to the complex situation of the oil reservoir, the pressure required by different water injection wells varies greatly, and the throttling energy consumption ...

AI Technical Summary

Problems solved by technology

[0004] 1. Once the pressure of the water injection pump station in the oil field is set, the high-pressure well will be under-injected, or even unable to inject water

[0005] 2. If the maximum water injection pressure is satisfied, the low-pressure well needs to be throttled, and the energy consumption is huge

[0006] 3. The longer the water injection time, the higher the pressure required for water injection. If the pump station does not have the conditions for boosting pressure, more and more wells will be under-injected

[0007] 4. If the pumping station is upgraded to increase the water injection pressure, the investment will be high and the energy consumption will be high

[0008] 5. The existing single-well pressurized water injection pump cannot effectively use the original pipe network pressure and consumes a lot of energy

[0009] 6. The existing single well pressurized water injection pump has a short service life, short maintenance cycle and high water injection production cost

[0010] 7. The existing single well booster water injection pump cannot realize automatic control and remote control
