裂缝与毛管的流动性能差别探讨

A Discussion on the Property Difference between the Fracture and the Capillary

用流体力学的原理论证了岩石中裂缝与毛管之间液体流动能力的差别以及变形毛管的流动性能，得出裂缝中流体的移动规律为抛物线函数。当固相岩石的外形轮廓相同，孔道截面形状为裂缝时，液体的流动能力是截面形状为毛管的流动能力的一倍以上；岩石中裂缝的出现会使流动能力突然增大；变形毛管的流动能力极易接近裂缝的流动状态．

The regularity of liauid moving in the fracture is a style of parabolic function. When the outline,of solid- state medium are alike, the flowing ability in fracture pattern may be twice as much as that in the capillary. The occtirrence of fractures would abruptly increase the moving ability in the rock. The flowing ability of modified capillaries is liable to close to that of fractures .
