Low-Cost Fracturing Technology in Normal-Pressure Shale Gas Reservoirs in Wulong Block

  • 摘要: 武隆区块常压页岩储层能量低,产量较低,实现效益开发难度大,为此,开展了低成本压裂开发技术研究。在分析武隆区块压裂改造技术难点的基础上,进行了诱导应力计算、压裂裂缝模拟和压裂费用对比,优化了压裂段长、簇数和压裂施工参数,优选了压裂材料和压裂设备,形成了“短段长+单簇滑套+低黏滑溜水+低成本石英砂+高砂比连续加砂”的压裂施工工艺,并在武隆区块A 井进行现场试验。通过应用无限级滑套完井工艺和实时调整现场压裂参数,A 井压后产量与同平台“中等段长+密切割+全陶粒支撑剂”压裂井产量相当,压裂成本降低52.8%,并实现了单井单日8 段压裂施工。低成本压裂技术为武隆区块常压页岩气的效益开发提供了新的技术途径。
