【摘要】 曲率作为一种描述地质体弯曲程度的几何属性,与地质体的受力程度成正比,进而也与因受力而形成的裂缝的发育特征高度相关。本文以柴达木盆地昆北地区中部A区块为例,应用俄克拉荷马矿业大学的AASPI软件提取地震反射面的曲率属性,如最大曲率、最小曲率、最正曲率及最负曲率等,在分析、对比各个属性优缺点的基础上,找到了一套适用于该区的应用曲率属性预测裂缝发育带的方案。更多还原

【Abstract】 As a geometric attribute to describe the bending degree for a geologic body,the curvature attribute is proportional to the stress degree of the geologic body,as a result it is highly relevant to the fracture’s development characteristics formed by the stress.In this paper the A Block in the middle of Kunbei area in Qaidam Basin was taken as study area and the AAPSI software from Oklahoma Mining University was utilized to extract the curvature attributes of the seismic reflection surface,such as maximum curvature,minimum curvature,maximum positive curvature,maximum negative curvature and so on,then based on the effective curvature attributes selected by attribute optimization process,a suitable solution for this area in which the curvature attributes were utilized to predict the fracture-developed zone was found out in this paper.更多还原
