| 摘 要： | 断裂与裂缝多为统一的应力场下破裂程度和相对位移量不同的破裂构造,都具有自相似性,满足分形理论。应用分形几何理论研究了贝尔凹陷布达特群潜山顶面断裂发育的平面分形特征和布达特群取心井段上裂缝的分形特征,并建立了二者之间的定量关系。基于断裂的分形特征尝试性地去预测有利的裂缝发育带,以期为裂缝的预测提供新的途径。研究结果表明,断裂信息维越高,裂缝信息维也越高,裂缝越发育。裂缝信息维大于1.4的区域是布达特群裂缝发育的有利区。

| Abstract: | Both fault and fracture are the cracks with different relative displacements and broken extents,and are formed in the same stress field.They are complex anomalistic object of self-conformability,so it is possible to study them by the fractal theory.Based on the studies on the planar fractal distribution of the faults on top of the buried hill of the Budate Group in the Beier depression and the vertical fractal character of the fractures in the cores of the Budate Group from the buried hill,an quantificational relation between them has been established and applied in forecasting favorable fracture-developed area to offer an new method to predict fracture.The forecast results show that the higher the information dimension of faults is,the higher that of fractures is, where the information dimension of fracture is more than 1.4 is the favorable fracture-developed area. |
