注入井套漏识别井口设备研制与应用

Development and Application of Injection Well Casing Leak Identification Device

基于大庆油田注入井普遍采用可洗井封隔器封隔层位,可对注入井套管反注水,提出了从套管投源找漏,为此研制了注入井套漏识别井口设备。应用该设备已在多口注入井中取得成功,结果表明,该设备具有找漏施工作业时间短、成功率高、节约作业费用等优点。

In the Daqing oilfield, the injection well is widely used in the well packer, which can inject water in the injector well. It is proposed to find the leak from casing source, and the leak detection equipment used in the injection well was developed. Application of the equipment has been successful to find the leak points in several injection wells. The results showed that the equipment has many advantages, such as short-time operation, high success rate, and operating costs saving, etc.
