提高火驱注气井符合率的方法与实践

Method and Practice of Improving Coincidence Rate in Fire Flooding Gas Injection Wells

针对火驱注气井符合率低,影响火驱开发效果的问题,从注气井的日常管理入手,对影响注气井合格率的因素进行详细的分析。对现有的工艺流程进行了优化,对设备配件进行了改进,同时建立相应的管理制度。措施实施后提高了机组效率,实现了稳定的压力、流量、空气注入,提高了注气合格率。

With view to the problem of low coincidence rate affecting the oilfield development in the fire flooding well,the factors influenced the qualified rate of the steam injection well were analyzed in detail from the viewpoint of the well daily management. The existing technological process was optimized,the equipment parts were improved,and the corresponding management system was also established at the same time. After the implementation of the measures,the unit efficiency was improved,the stable pressure,flow,air injection were achieved,and the steam injection qualified rate was improved.
