FLOW REGIM FOR SHALE GAS IN EXTRA LOW PERMEABILITY POROUS MEDIA

Funds: The project was supported by the Development and Evaluation Techniques for Tight Sandstone Gas (2011ZX05013-002).
  • 摘要: 基于页岩气藏复杂孔隙结构和页岩气在纳米孔隙表面的滑脱和吸附-解吸附等现象,通过引入表观渗透率,修正Darcy渗流模型,得到了页岩气渗流本构方程. 将计算结果与Darcy模型计算结果进行了比照,结果表明,在产量定常情形下,基于非Darcy渗流模型得到的井底压力高于Darcy流结果; Darcy流模型得到的压力衰减速度较快,改进后的渗流模型更能准确描述与表征页岩气渗流过程;研究结果可为页岩气藏的经营与管理提供基础参数.
