| 摘 要： | 实验室研究和实际开发效果证明低渗透气藏在成藏机理上与中高渗透气藏存在较大差别,在储层内部,流体的渗流规律也与中高渗透气藏有较大差别.因此,提出一个新的非线性渗流模型,并建立相应的非线性渗流数学模型.该模型包括了储层中由于液相的存在而形成的边界层以及启动压力的影响,认为在低渗透气藏中流体的流动大部分属于非线性流动,储层中液相的存在对气相的影响是不能忽略的. |
| 关 键 词： | 低渗透气藏 渗流机理 非线性渗流 边界层 启动压力 |

| Abstract: | Low percolation gas reservoirs are definitely different from the high ones in the mechanism of becoming reservoir,so does the influent mechanism.Both the experiment results in laboratory and the exploration results of cites have proved it.So the present paper puts forward a new nonlinear influent model,and sets up a new relevant nonlinear influent mathematical model.The model includes the effects of boundary layer and actuating pressure which exist in the reservoir because of the existence of liquid.This paper considers that most of influence in the low percolation reservoirs is nonlinear,and the effects of liquid cannot be omitted. |
