aZD-III暂堵效果好:屏蔽环深度小,强度大于11Mpa,反排解封堵的渗透率恢复值(和OSR联合使用)大于80%。 ZD-III stops up the effect to be good temporarily: The shield ring depth is small, the intensity is bigger than 11Mpa, instead mediates trap the penetration coefficient to restore the value (and...
a研究低渗透油田主要的目的在于可以封堵或降低高渗透层的吸水能力,增加低渗透的吸水量,减少无效注水,调整吸水剖面,有效的扩大水驱波及系数,调整产业剖面,降低产水量,提高产液量,从而提高注水开发采油的水驱采收率 Studies the low seepage oil field main goal to lie in may seal off or reduce the high filter...
a由表1可作如下分析:整个井组总体调堵效果较好,开始时绝大部分超大和大孔道被封堵。所以注胶后,又两年的注水开发,扩大了注入水的波及体积,形成了大量过水的中孔道和小孔道,提高了采收率。但随着注水开发的继续,地层中会形成新的高渗透条带,例如注水井到生产井18-9之间,该生产井的产水量增长速度较快,已达到注胶...
