| 摘 要： | 为充分挖掘J16断块兴隆台油层的潜力,对广泛发育的河口砂坝砂体内部构架进行了精细刻画,讨论了厚层内部存在的大量隔夹层特征。研究表明,在开发后期该类隔夹层具有物性遮挡的作用,可控制剩余油的分布。通过对该类潜力层优化射孔,能够有效地抑制底水上升。现场实践表明,对隔夹层实施的挖潜措施是提高河口坝厚层砂体油藏采收率的有效途径。

| Abstract: | Debouch bar sandbody is extensivly develoed in Xinglongtai Reservoir of Block J16,a large number of interbeds exist within the thick layer,lithology is gray,brown gray mudstone or muddy siltstone,electric curve shows a relatively low value,so it forms the uneven thickness of the impermeable formation or low permeability bands.These interbeds actually have shielding properties and distribution of remaining oil at extra-high water-cut stage.Remaining oil exists in the thick layer on the top of interbeds.Throu... |
