低渗透油田注水系统效率评价及技术优化

摘要

由于低渗透油田在注水开发作业中，注水压力高、管网复杂，注水系统效率一直较低。从化子坪油田实例入手，按流程节点进行注水系统效率的测试、评价和优化，细化了注水系统效率的影响因素，并针对性地提出优化方案，实施后并取得了较好的节能效果。%In low permeability oilfield high-pressure water injection system is often used,a large and complex pipe network,system efficiency has been low reason based on the 4th production plant water injection system efficiency testing in Changqing Oilfield,evaluation and optimization. And a new method is used to evaluate the system efficiency by the process node,highlighting the factors affecting of efficiency and puts forward optimization.Water injection system efficiency was significantly improved.
