| 摘 要： | 大牛地气田储层属于低压致密气层,非均质性强、孔喉直径小、毛管压力高、多层叠置且层间跨度不等导致储层保护和加砂压裂难度大.通过研究提出了采用液氮增能低伤害压裂液体系,降低对储层的伤害,有效地保护了储层;采用大型加砂压裂技术,增加了裂缝长度,扩大了泄气面积,提高了单层产量,气产量由200 m3/d提高到7.23×104 m3/d;采用不动管柱连续分层压裂工艺技术实现了多层叠置气层均衡改造,压裂投产作业时间缩短了近67%,费用降低了20.69%.

| Abstract: | The Daniudi gas field belongs to a reservoir of lower pressure and tight gas with a low pressure,a strong heterogeneity,a small diameter of pore and throat,a high capillary pressure,a cha-racter of multi-zone superimposed and varies gap distance between zones,which results in difficulty in reservoir protection and fracturing.A method of low damage fracture fluid with liquid N2 is adopted,which can decrease the reservoir damage and protect reservoir.Large-scale fracturing can prolong fracture length,enlarge ... |
