| 摘 要： | 从数学规律的角度,应用分形理论,对构造裂缝的分布发育规律进行研究.分数维D值越大,说明构造裂缝分布越均匀,各向异性较强,构造裂缝的分布发育较好.与走滑断裂属同一构造应力场的构造裂缝,随着距离走滑断裂距离的增大,分数维D值呈指数减小;随构造裂缝面密度的增大,分数维D值呈线性增大.分数维D值大小更能体现构造裂缝分布的均匀程度和各向异性,同时考虑构造裂缝面密度和分数维,引用发育程度f来表征岩石破裂程度.对裂缝油气藏来说f,越大表明岩石破裂程度越高,储层裂缝越发育.靠近断裂岩石破裂程度高,有利于油气的运移.

| Abstract: | Based on fractal theory regardless of geological conditions,this paper discussed the distribution regular pattern and development of structural fractures.High fractal dimension(D)shows that the structural fractures distributed evenly and have a good anisotropy.The fractal dimension decreases at an exponential rate with the increasing of the distance away from the strike-slip fault.The fractal dimension increases at a linear rate with the increasing of fracture density.The fractal dimension has a better desc... |
