| 摘 要： | 为了研究不同人造裂缝对渗透率的影响,介绍了不同岩心造缝方法及其特点,并开展了室内物模实验,测定不同人造裂缝的渗透率。结果表明:裂缝的克氏渗透率随裂缝平均宽度的增加而增大,随围压的增大而减小,且存在一定的线性关系。通过总结不同人造裂缝渗透率的变化规律,加深了对裂缝的认识,为更好地开采裂缝性储层提供一定的理论依据。

| Abstract: | The effects of various artificial fractures initiated by different means on permeability have been studied. Laboratory physical simulation experiments have been conducted to measure the permeability of various artificial fractures. The study results indicate that the Klinkenberg permeability of fractures increases with average width of fractures and decreases with the increase of confining pressure,displaying certain linear relationship. The permeability variation of various artificial fractures is summarized,thus deepened understanding on factures and provided theoretical guidance for efficient development of fractured reservoirs. |
