摘要
文章对注水井在调试周期内注水量发生变化,分层注水失败影响到开发效果的原因进行了分析。通过资料统计分析、现场试验等方法,找出影响注入量变化的原因主要是由地层压力波动、井下管柱和工具工作状况、洗井措施等因素造成的。并提出一些改变影响因素的建议。
This paper,analyses both the change of water injection rate in debugging period and the reason why the failure of separated zone water injection has an effect on the development impact of the injection well.We find out the main factors such as formation pressure fluctuation,down hole string,measures of well flushing,tool mode of operation and so on,have an impact on injection rate by means of statistical analysis and field experiment.Furthermore,some advice on effect factor is put forward.
