摘要
利用准噶尔盆地腹部莫北地区实际测井资料建立了地层断层模型,模拟不同勘探阶段地震资料上小断距断裂的地震响应特征,指出在地震采集、处理过程中,影响小断裂识别的因素主要为道间距、地震子波主频和随机噪声。提出了利用区块断裂正演模拟结果为模板和常规地震资料相结合进行小断裂识别的方法。
Using real well log data from Mobei area in hinterland of Junggar basin,a fault model was developed,modeling seismic response features of minor fault throw fractures in different exploratory stages,outlining the factors af-fecting recognition of minor faults during seismic acquisition and processing.And method for identification of minor faults by applying forward modeling of regional faulting as a mockup integrated with conventional seismic data was pro posed.
