浅层地震勘探在隐伏断裂探测中应用——以蜀山断裂为例

Application of Shallow Seismic Exploration to Detecting Buried Faults--Taking Shushan Fault as an Example

以六安地区蜀山断裂探测为实例,在精心分析了收集的地质资料及现场场地条件的前提下,重点研究了地震反射和地震层析成像两种勘探方法的实际运用情况。野外根据两种方法试验情况,选择了准确的观测系统,并仔细对比了采集参数,取得了合格的原始数据;室内采用适当的处理软件和正确的处理参数,取得了丰富的成果图像。通过两种方法的成果比对,并结合钻井资料,阐述了蜀山断裂的位置及其性质。结果表明,两种地震勘探方法在该地区隐伏断裂探测中具有良好的运用效果。

Taking Shushan fault detection in Lu'an area as an example,this paper focuses on the practical application of such two detection methods as seismic reflection and seismic tomography on the premise of carefully analyzing the collected geological data and site conditions.With these two methods the field test has selected an accurate observation system,carefully compared the acquisition parameters and obtained qualified original data.Rich images of the indoor test have been obtained with appropriate processing software and proper processing parameters.By comparing the results of these two methods and combining with the drilling data,this paper has accurately explained the location and nature of the Shushan fault.These two methods for seismic prospecting have good application effects in the exploration of hidden faults in this area through this work.
