摘　　要：四川须家河储层物性差、纵向上含气层系多,层间跨距变化大,单层产能低,为实现纵向上各气层的均衡改造,提高单井产量,降低作业周期和成本,开展了不动管柱四层分层压裂技术,在包16井取得成功应用,突破了以往封隔器分层最多三层的限制,具有广阔的推广应用价值。Sichuan Xujiahe reservoir is poor of physical property difference,has many vertical gas-bearing formations,changes greatly in interlayer span,whose productivity of single-layer is low.In order to realize the longitudinal balanced transformation,improve single well production,reduce the operation cycle and cost,four layers fracturing technology without moving string is carried out and applied in Bao16 well successfully,which breaks through the previous constraint of up to three layers with the packers,has a broad applied value.
