Fissure can be provided not only for shale gas accumulation space,but also for migration pathway of gas production.As a kind of low permeability and low porosity reservoir,mechanism of shale gas production is complicated,involving the relationship between adsorbed gas content and free gas content,natural tiny fissure and fracturing induced fissure.We discuss type of muddy shale fissure,identification,basic parameters (width/opening,length,spacing,density,strike and dip,filling,dissolution reconstruction,etc.),poroperm characteristics,geologic background,and the effects on accumulation and production of shale gas.There are five kinds of fissure in the muddy shale,including structural fractures (extensional crack,shearing crack and extensional\|shearing crack),interlayer lamellation crack,bedding glide crack,diagenetic shrink micro-cracks,and abnormal pressure crack of organic evolution.Geologic factors controlling the fissure formation are complex,such as regional tectonic stress,tectonic position,sedimentary diagenesis,lithology,lithofacies,poroperm characteristics,and formation pressure.The identification characteristic of fissure and its formation mechanism is different,so the effect on adsorption,segregation,and response to seepage property of shale gas is not identical.Exploration target zone of shale gas should be set on muddy shale with higher permeability or reconstructional fissures.
