Establishment of the Chart of the Artificial Fracture Width Versus Permeability of Carboniferous Carbonate Rocks in East Sichuan and the Classification of Reservoir

本文通过岩石人工裂缝造缝试验、建立了人工裂缝宽度与渗透率关系图版及其关系式,定量地将裂缝宽度引入碳酸盐岩储集层分类,并结合储集岩孔隙结构与渗透率关系图对川东石炭系裂缝-孔隙型碳酸盐岩储集层进行了分类。

The Carboniferous gas pools in East Sichuan belong to fracture-pore type reservoirs and it is very difficult to determine the permeability with core,which influences the systematic study of fracture per- meability. In this paper,the chart of artificial fracture width versus permeability and its relation are es- tablished through the experiment of artificially fracturing in the rocks and the fracture width is quanti- tatively led into the classification of carbonate reservoirs as well as combined with the chart of pore structure versus permeability of this reservoir rocks, the Carboniferous fracture-pore type carbonate reservoirs in East Sichuan are classified.
