AI Technical Summary

Benefits of technology

The technical effect that this innovation helps make it easier for multiple types of equipment (such as an oil well) at different locations from being driven together without having too much power or requiring more maintenance). This makes them better suited for use during certain times when there's no demand on their main purpose.

Problems solved by technology

This patents describes two technical problem addressed during drilling operations: efficient water supply requires more than half of its own energy usage compared to traditional methods like drainage or hydraulic fracturization. Additionally, there may exist issues related to maintaining adequate levels of hydrocarbon productivity due to factors such as overfishing and poor well performance. Overall, this patented solution proposes a new approach called Surface Engineering which involves injecting water into oil sands efficiently while minimizing their impact on environmental resources.

Embodiment

[0014] Such as figure 1 As shown, the multi-stage centrifugal water injection pump system provided with booster pumps involved in the present invention is mainly composed of a multi-stage centrifugal water injection pump 1 connected to the water source 3 and several water injection pipes connected to the multi-stage centrifugal water injection pump 1 respectively. 2 structure, the multi-stage centrifugal water injection pump 1 and the water source 3 are also provided with a booster auxiliary pump 4.

[0015] A flow meter 5 is arranged between the auxiliary booster pump 4 and the water source 3 .

[0016] A throttling valve 6 is arranged between the multistage centrifugal water injection pump 1 and the water injection pipe 2 .

[0017] In the present invention, a low-power booster auxiliary pump with a wide working range is connected in series before the multi-stage centrifugal water injection pump, such as figure 1 As shown, the high-power multi-stage high-pressure centrifugal

Abstract

The invention discloses a multistage centrifugal injection pump system with a supercharging attached pump. The multistage centrifugal injection pump system with the supercharging attached pump mainly includes a multistage centrifugal injection pump (1) connected with a water source (3), and a plurality of water injection pipes (2) respectively connected with the multistage centrifugal injection pump (1). The supercharging attached pump (4) is arranged between the multistage centrifugal water injection pump (1) and the water source (3). By that the low-power supercharging attached pump with a wide working range is connected in series before the multistage centrifugal injection pump, the multistage centrifugal injection pump system with the supercharging attached pump enables the high-power multistage centrifugal injection pump to work in a narrow high-efficient working area in the water injection system, adjusts the output delivery lift and flow of a water injection pump station, and improves the operating efficiency of the pump station.
