3）the Classification based on pore size a. capillary micropore b. capillary interstice c. capillary superpore 油藏物理学—储层岩石的孔隙结构及孔隙度
a.capillary micropore pore diameter:<0.2um fracture width:<0.1um characteristics:attraction between molecules is great,and fluid flow through pore media need very high pressure gradient. Note:Shale porosity
a. capillary micropore pore diameter: <0.2μm fracture width: <0.1μm characteristics: attraction between molecules is great, and fluid flow through pore media need very high pressure gradient. Note: Shale porosity
a.capillary pore pore diameter:0.2~500um fracture width:0.1~250um characteristics:Fluid flow through porous media need to overcome gravity. Note:sandstone porosity
a. capillary pore pore diameter: 0.2~500μm fracture width: 0.1~250μm characteristics: Fluid flow through porous media need to overcome gravity. Note: sandstone porosity
a.capillary superpore pore diameter:>500um fracture width:>250um characteristics:Fluid flow through porous media need only gravity Note:Large cave,large cracks,lack of cement or unconsolidated sandstone porosity
a. capillary superpore pore diameter:＞500μm fracture width: ＞250μm characteristics: Fluid flow through porous media need only gravity Note: Large cave, large cracks, lack of cement or unconsolidated sandstone porosity
