摘要
为解决中低渗碎屑岩储层供液不足问题,在塔河油田引进了复合射孔技术。根据储层分布情况,确定了射孔井段、射孔相位和射孔枪型,同时考虑地层破裂压力、套管安全性能、穿深及均衡渗流能力能因素,确定了最终复合火药用量。和与之相邻且储层物性非常相近的常规射孔井的射孔效果进行对比评价表明,复合射孔形成孔缝结合的渗流体系,能够改善地层的导流性能,提高供液能力。
To solve the problem of insufficient fluid supply in oil well in medium-low permeability reservoirs,a composite perforating technique is introduced in Tahe Oilfield.Perforation interval,its phase and perforation gun are determined according to the reservoir distribution.The compound perforating powder is determined according to formation breakdown pressure,casing security,perforating depth and equalization of percolation ability.Perforating effect between the adjacent wells with similar reservoir property is compared in conventional perforation.The composite perforating seepage system can improve flow distribution performance,and increase fluid supply capacity.
