摘要
Abstract
The ultra-low permeability reservoir has the characteristics of poor pore throat structure, poor physical properties and strong heterogeneity.The seepage mechanism of ultra-low permeability reservoir is also different from that of conventional reservoir.In the initial stage of reservoir, the production is high, but the rate of decline is fast, and the reservoir keeps low pressure, which leads to low efficiency and slow effect of water injection method.Through researching the permeability law, reservoir sensitivity and facies permeability law of ultra-low permeability reservoir, this paper analyses the seepage mechanism of ultra-low permeability reservoir, which is of great significance to guide the later stage production of reservoir and achieve the goal of high-efficiency development of ultra-low permeability reservoir.关键词
