注水开发油田在水驱开发后期油井普遍出现日产液和含水率大幅度上升。结合江汉油田注水管理现状,运用嘴流规律分析问题成因,通过提高注水管理水平,控制含水率上升,降低无效排液,可提高经济效益。对嘴流规律的反向理解,可以指导注水井现场的管理工作,从注水井管网设计到落实注水井配注,均有理可依。结合嘴流规律进行注水实践,能降低现场操作难度,提高工作效率。注水管网设计之初应结合现场投捞测试所取得的资料,预测注水井工作状况,有针对性进行管网设计,能避免重复建设。 Water injection development of oil wells in the latter part of the water flooding generally appear Nissan liquid and water content increased significantly. Combined with the current situation of waterflooding management in Jianghan Oilfield, the author analyzes the cause of the problem by using the law of mouth flow, and increases economic benefits by increasing the waterflooding management level, controlling the water cutoff and reducing the ineffective drainage. The reverse understanding of the law of mouth flow can guide the management of water injection well site, from the design of water injection well pipe network to the implementation of injection well injection, are reasonable to follow. Combined with the law of mouth flow water injection practice, can reduce the difficulty of field operations, improve work efficiency. The design of water injection pipe network should be based on the data obtained from the fishing test in the field to predict the working conditions of water injection wells and to design the pipe network in a targeted manner to avoid redundant construction.
