随着新工艺的出现,实际上对采用水力压裂工艺在渗透率方面没有限制。根据传统观念,只在低渗透层中采用水力压裂工艺。例如,水力压裂工艺可用的渗透率k<0.005μm~2的低渗透、渗透率0.0050.05μm~2的高渗透油层;渗透率k>0.0005μm~2的低渗透、渗透率0.00050.005μm~2的高渗透气层,对于不同的渗透率应选用相适
With the advent of new processes, there is virtually no limit to permeability with hydraulic fracturing. According to the traditional concept, the hydraulic fracturing process is used only in the low permeability layer. For example, a hydraulic fracturing process may be used with a low permeation rate of k <0.005 μm -2, a medium permeability with a permeability of 0.005 0.05 μm -2, a permeability k > 0.0005μm ~ 2 permeability, the permeability of 0.0005 0.005μm ~ 2 high permeability gas layer, permeability should be used for different permeability
