老井复查正在成为各油田新增储量和产量的较好方法之一,它具有投资少、风险小、见效快的特点。而测井技术在塔河油田老井复查的应用中取得了较好的效果,主要体现在3个方面1)增加产层,实施挖潜增效;2)提供上返层位和指导老区滚动开发;3)对老区浅层实现探索,扩大含油气范围。同时,通过老井复查,得到一个启示,老井复查应逐步向非目的层系和塔河外围扩散,利用其形成的油气水识别技术方法,重新认识,取得更多油气成果。

Re-evaluation of completed wells is a good way to improve reserve and production in many oilfields,due to less investment,less risk and faster return.Application of logging technique in completedwell re-evaluation in the Tahe Oil Field achieved several good results:1)More producing formations,more potential and higher efficiency;2)Providing back layer and guiding completed region rolling deve-lopment;3)Exploring in upper layers of completed region and expanding petroliferous range.Mean-while,re-evaluation of completed wells indicated that the re-evaluation should expand to untargetedstrata as well as the surrounding area of the Tahe Oilfield.The identification methods of oil,gas andwater might be used to recognize and obtain more oil results.
