海上油田注水能力提升研究

Study on Improving Waterflooding Ability of Offshore Oilfields

针对当前海上某油田注水井存在不同程度的注水能力不足问题。通过计算注水井管柱沿程摩阻和水嘴嘴损压力,分析沿程摩阻和嘴损对平台注水能力的影响,为井口注入压力提升提供定量参考,同时对该油田注水井注水压力与流量关系进行分析,评估注水井可提升注水量并按照可提升注水量对注水井进行吸水等级划分,针对各等级注水井提供相应建议措施,为平台后续注水井管理提供理论参考和技术支持。

In view of the current waterflooding wells in a certain field in the sea, there is a problem of insufficient water injection capacity. By calculating the friction along the pipeline and the mouth pressure, the influence of the friction and mouth loss along the path on the water injection capacity of the platform is analyzed to provide a quantitative reference for the pressure increase at the wellhead. At the same time, the injection pressure and The relationship between the flow rate and the water injection well can be evaluated. The water injection rate can be increased and the water injection grade can be divided according to the amount of water that can be raised. The technical scheme for water injection enhancement of the oilfield is prepared so as to provide theoretical reference and technical support for the subsequent well management of the platform.
