摘要
单点高密度数字检波器地震勘探技术作为一种全新的地震勘探方法,将其用于煤田地震勘探,针对单点高密度数字资料的特点,进行多域联合去噪,利用矢量中值滤波进行随机噪声衰减,在十字排列域压制面波,并利用Curvelet变换进行弱信号检测。最终得到相比常规模拟检波器资料,频带更宽、高低频更丰富、分辨率更高的叠加剖面。
Single-point high-density digital seismic exploration is a new seismic exploration method. It is used in the coal seismic exploration. Actualize denoising in multi domain which is using vector median filtering for random noise attenuation, removing ground roll by the application of 3D conical filtering technique in the cross-spread and detecting weak signal with curvelet transform. Finally,obtain stack section which has wider bandwidth, more signals with high and low frequency, and higher resolution than conventional analog geophone data.
