摘要： 鄂尔多斯盆地红河油田长9段油气资源潜力巨大，油气成藏和产能均受控于断层裂缝系统。裂缝主要为区域构造裂缝和断层共（派）生裂缝。在对野外露头、岩心、成像测井裂缝特征分析的基础上，利用有限差分法软件对燕山运动期和喜马拉雅运动期的古应力场进行模拟；利用裂缝发育密度的控制函数对断层共（派）生裂缝进行预测。评价结果认为，裂缝主要分布在砂体发育区及断裂带附近，预测精度达78%，为优选勘探目标区提供了地质依据。

Abstract: The Chang?9 member in Honghe oilfield of Ordos basin is of huge oil and gas resource potentials, its hydrocarbon accumulation and productivity are controlled by the fault/fracture system. The fractures are mainly regional structural fractures and fault?associated or derived fractures. Based on the fracture characteristics of outcrop, cores, imaging logging and genesis analysis, the palaeostress field of Yan?shan and Himalayan period is simulated by means of finite difference method. At the same time, the fault?associated or derived fractures are predicted based on the control function for fracture density near faults. Comprehensive evaluation results show that the fracture developed area is mainly distributed in the sand body area and near the fault zone, with the prediction accuracy of 78%, providing reasonable geologic bases for optimization of the favorable exploration target area
