| 摘 要： | 在对阿曼Daleel油田下白垩统Shuaiba组上段的岩芯及成像测井裂缝特征进行分析的基础上,利用过断层的水平井成像测井资料,开展对断层两侧的裂缝发育情况研究,分析认为裂缝发育密度与离断层的距离相关,提出裂缝成因主要受区内走滑正断层所控制.研究建立的3类不同规模的走滑正断层带裂缝密度分布函数,实现了对阿曼Daleel油田下白垩统Shuaiba组上段断裂带裂缝分布的定量评价. |
| 关 键 词： | 走滑正断层 断裂裂缝带 密度分布函数 裂缝分布评价 |

| Abstract: | According to the analysis of the core and FMI characteristics of the fractures and FMI data of the horizontal well passing through the fault,this paper discussed the fracture develop-ment near the fault. It was showed that the fracture density was related to the distance from frac-ture to fault,and the fracture genesis was controlled by the normal strike-slip fault. The function of distribution of the fracture density of three different scales of normal strike-slip fault was ob-tained in the research and the distribution of fractures in the normal strike-slip fault zone of upper Shuaiba Member of Lower Cretaceous in Daleel oil field in Oman was evaluated t quantitatively. |
| Keywords: | down strike-slip fault faulted fracture belt density distribution function evaluation of fracture distribution |
