除了挤水泥胶结射孔孔眼外, 还有快速、经济、有效的机械堵水措施, 其中包括通过电缆、钢丝或连接管、连续油管组成的修井作业管柱来下桥塞。很多措施可以通过油管来进行, 可以不取出完井段套管。此外, 还有隔离尾管, 即将两个或更多的可膨胀式封隔器通过中间插入尾管连接在一起, 可有效降低封隔水的入口流量。有些情况下跨式封堵工艺能够通过射孔孔眼将化学调剖堵水剂注入产水层段, 从而降低水相渗透率, 提高油相渗透率。
In addition to cementing the perforations, there is a fast, economical and efficient mechanism for mechanical containment of water, including workover workstations made up of cables, wires, or coiled tubing, and coiled tubing. Many measures can be carried out through the tubing, you can not remove the completion casing. In addition, there are isolation tailpipes, that is, two or more inflatable packers connected through the middle of the tail pipe, which can effectively reduce the inlet flow of the packing water. In some cases, the cross-plugging process can inject the chemical profile-control plugging agent into the aquifer section through the perforation aperture, thereby reducing the water-phase permeability and increasing the oil-phase permeability.
