Sensitivity Analysis of Production in Fractured Shale Gas Reservoirs

  • 摘要: 考虑气体渗流、解吸附效应、储层压缩性和滑脱效应,建立了页岩裂缝系统产能的全耦合数学模型.采用有限元方法求解基质和裂缝流场,计算结果与已有的研究结果吻合,验证了模型的正确性.在此基础上,分析了裂缝半长、条数、间距等参数对产能的影响以及解吸附效应对产能的作用.结果表明:裂缝参数之间存在相互作用.裂缝半长对产能的影响最大,裂缝条数的优化与裂缝半长有关;在生产中后期,解吸附效应可以提供相当可观的气体产量,对稳定产能有重要意义.该模型可以为页岩压裂设计提供理论指导.
