聚合物微球深部调剖技术在葡萄花油田的适应性探讨

Discussion of on adaptability polymer microspheres deep profile control technology in Putaohua Oilfield

随着葡萄花油田进入高含水开发阶段,低效无效注水循环严重,层内层间矛盾日趋突出,为解决上述问题,注水井深部调剖技术得到广泛应用,但成本较低的调剖技术如碱土等存在无法降解的问题,影响油田开发后期的聚驱等开发效果;而可降解调剖技术如缓膨颗粒等,单井施工费用约60万元,施工费用较高,推广受限。为满足油田调剖实际需求,亟待开发高效、成本低、可降解的调剖技术。为此,提出开展聚合物微球逐级深部调剖技术试验。

With the Putaohua Oilfiled has entered the high water content development stage which with ineffi- cient injection cycle seriously. The contradiction between layers increased prominently. To solve the problem, the water - poured well depth control technology was applied widely. But there was a degradation problem with low cost profile technology which affects the development effect. The degradable profile control technology such as slow expansion particles etc.,Single well construction costs about 600000 yuan,Promotion Limited by the construction cost is higher.In order to meet the actual needs of oilfield profile,The need to develop high performance, low cost, biodegradable profile control technology.was needed to be developed the polymer microspheres stepped deep pro- file control technology experiment .
