| 摘 要： | 为了明确冀中坳陷孙虎潜山带裂缝发育特征，通过地震、岩心及成像测井等资料归纳裂缝类型，对裂缝参数进行定量表征，分析裂缝主控因素并定量预测裂缝的分布规律。结果表明，研究区碳酸盐岩储层主要发育北东—南西向的高角度构造裂缝，裂缝充填程度较弱有效性高。单井线密度分布在1.0~6.8条/m，裂缝高度主要分布在10~40 cm。构造变形强度大、断层发育程度高的部位裂缝的发育程度越高；白云岩中平均裂缝密度为0.68条/m，裂缝最为发育；埋藏深度越低，裂缝发育强度越大，厘定出风化壳控制优质储层厚度为50~160 m。通过建立分形生长模型预测孙虎潜山带裂缝分布规律，预测结果与测井解释结果一致。

| Abstract: | In order to clarify the characteristics of fracture development in the Sunhu Buried Hill Zone in Jizhong Depression，the fracture types were summarized through seismic，core and imaging logging data，fracture parameters were quantitatively characterized，the main controlling factors of fractures were analyzed，and the distribution of fractures was quantitatively predicted.The results showed that the carbonate reservoirs in the study area mainly develop high-angle structural fractures in the northeast-southwest direction，and the filling degree of the fractures was relatively weak and the effectiveness was high.The linear density of a single well was distributed from 1.0 to 6.8 bars/m，and the fracture height was mainly distributed from 10 to 40 cm.The higher the structural deformation intensity and the higher the degree of development of faults，the higher the degree of fracture development；the average fracture density in dolomite was 0.68 fractures/m，and the fractures were the most developed；the lower the burial depth，the greater the fracture development intensity，which determined the weathering the thickness of the crust-controlled high-quality reservoir was 50~160 m.By establishing a fractal growth model to predict the distribution of fractures in the Sunhu Buried Hill Zone，the prediction results were consistent with the logging interpretation results. |
