| 摘 要： | 选取了断层的产状、断层力学性质、断层断面曲率、断面压力、最大主应力与断层走向夹角、断层两盘岩性配置关系和断层沿走向形态等8个评价因子,构建了断层封闭性评价模型。在不同的平面位置、不同的剖面深度半定量评价了研究区与4个主要局部构造相关的9条目标断层现今时期封闭能力。评价结果显示,从断层封闭性角度来优选,W10-1构造和W10-3构造最佳,W9构造中等,W10-2构造次之。

| Abstract: | Mode of fault occurrence, mechanical property of fault, cross-section curvature of fault, cross-section pressure of fault, the angle between maximum principal stress direction and fault strike, and lithology along the fault are selected to establish analysis model of sealing capacity of faults. Semi-quantitative assessment of sealing capacity of nine faults associated with four local structures is obtained according to different plane location and different depth. Result shows that sealing capacity of W10-1 and W10-3 is the best, W9 is the median, and W10-2 is the worst. |
