    Oilfield Water Injection Pump

    Oilfield Water Injection Pump

    The "Heart" of the Oilfield: Revealing How Water Injection Pumps Continuously Inject the "Water of Life" into the Reservoir Beneath the vast oilfield, crude oil does not flow out continuously on its own. As extraction proceeds, the formation pressure gradually decreases, like a slowly deflating balloon, unable to push the oil from deep underground to the wellhead. At this time, a powerful "heart" is needed—the oilfield water injection
