大庆油田进入高含水开发后期阶段,油田可持续稳产是目前的首要任务。油水井窜槽是目前影响油田开发效果的一个十分突出问题,严重影响注水、产液结构调整,影响细分注水效果,使得高含水层注水得不到有效控制,井区油井含水上升速度加快,对油田稳产、控水以及措施挖潜将产生一定影响,因此应及时采取封窜措施,降低油井含水,改善油田开发效果。通过对xx-xx井进行环空测试,发现P21油层产液异常,带着这个问题我们对它和与它相关的井开展分析。
Daqing Oilfield enters the later stage of high water-cut development, and the oilfield’s sustainable and stable production is the primary task at present. The channeling of oil and water wells is a very prominent issue that affects the development of oilfields at present. It has a serious impact on the adjustment of waterflooding and production fluid structure and affects the effect of subdivision waterflooding. As a result, waterflooding in high aquifers can not be effectively controlled, It will exert a certain influence on the stable production and water control of the oilfield and tapping the potential of the measures. Therefore, sealing and trapping measures should be adopted in time to reduce the water content of oil wells and improve the oilfield development effect. By conducting an annulus test on the xx-xx well, we found an abnormal fluid production in reservoir P21. With this problem we analyzed it and the wells associated with it.
