Description

Technical Field

[0001] The utility model relates to a downhole water injection pump, belonging to the technical field of water injection pumps. Background Art

[0002] As underground resources are mined more deeply, deficits appear between underground layers. It is necessary to inject water into the formation to maintain formation pressure and improve the efficiency of underground resource recovery. Water injection pumps are indispensable equipment in the process of injecting water into the formation.

[0003] The utility model with patent number 202320017316.6 provides an injection pump for oil field water injection. The utility model can fully shield and protect the main body of the injection pump through the setting of a protective box and an installation box. Through the setting of a multi-directional buffering protection mechanism, the main body of the injection pump can be fully buffered and unloaded in multiple directions to reduce the risk of damage to the main body of the injection pump due to large hard vibration force. In addition, the vibration amplitude can be reduced during the buffering process, thereby improving the working stability of the main body of the injection pump. However, when the existing injection pump runs for a long time, a higher temperature will appear on the surface. If a protective mechanism is set outside the injection pump, the heat dissipation effect of the injection pump itself will be affected, which will cause damage during long-term operation. Moreover, when the injection pump is running or vibrating, it will cause serious noise pollution, which brings inconvenience to the user. Utility Model Content
