| 摘 要： | 针对疏松砂岩的产能评价,研发了大型径向流井眼出砂及防砂模拟试验装置。以哈萨克斯坦肯基亚克YS油田为例,通过地层真实条件下大型出砂模拟实验,得出砂量、产量及出砂粒径的变化规律,以及储层、环空及防砂管内外的压降规律。针对四种不同防砂方式(金属编织网、金属棉、割缝管、割缝筛管砾石充填)进行了防砂后的产能评价试验,进行了出砂产量的分析。根据试验结果,提出了有限防砂、有效排砂、防粗排细的主要原则,优选出了适合于盐上油田疏松砂岩油田的防砂方式,现场应用获得了较好的效果,出砂明显减缓,检泵周期延长近5倍。

| Abstract: | An large scale sand production equipment,which simulated radius flow status near wellbore,was developed for unconsolidated sandstone production evaluation.A series of experiments for Kenkiyak YS oilfield,Kazakhstan were performed.It was got that the law of oil rate,sand production and sand size change with time,also pressure differential law of formation,annulus and sand control tube.Four methods of sand control,including metal intertexture meshwork,metal sieve,screen tube,screentube + gravel pack,were sele... |
