RVSP方法正演模拟及在煤田采空区中的应用
|
摘要
为了提高煤田采空区的地震勘探精度,精准定位采空区边界。在传统VSP地震数据处理成像方法的基础上,通过正演模拟系统地研究了RVSP地震数据处理成像方法,并对采空区填充物及大小分别建立模型进行地震正演模拟数据分析,研究其成像特征。利用正演模拟研究成果,对某水务工程关键地段煤田采空区地震试验数据进行精细处理,并取得了理想的成像效果;形成了一套适合煤田采空区RVSP地震数据处理成像方法,对精准探测煤田采空区具有重要的实际意义。
In order to improve the seismic exploration precision of coal mine goaf and precisely positioning coal mine goaf boundary, on the basis of traditional VSP seismic data processing method, the paper has systematically studied the imaging method of RVSP seismic data processing through forward modeling system, and built forward modeling used to build model of filling materials and size to analyze the seismic forward modeling data in coal mine goaf to study the imaging features. Using the results of the forward modeling, seismic test data of the key sections of the mine goaf in were finely processed the coal mining goaf on the key section of a water project, and the ideal imaging results have been achieved. A set of imaging method suitable for RVSP seismic data processing was formed, which has important practical significance for the accurate detection of coal mine goaf.
