金属矿地震资料处理研究

针对金属矿地震勘探地震资料信号非常弱而噪声却非常强的地震资料的特点，以河南省栾川金属矿地震勘探项目为例，研究了有利于提高金属矿地震资料信噪比和分辨率的地震数据处理技术和流程，利用不同处理系统的优势模块反复试验，确定最终处理参数，优选一套从折射波静校正—室内初至波剩余静校正—反射波剩余静校正的综合静校正技术解决静校正问题，运用多域联合去噪的方法压制噪音，应用球面扩散补偿技术从纵向上对能量进行补偿，联合使用地表一致性振幅补偿技术对炮点、检波点振幅进行补偿使横向能量均衡。运用叠前时间偏移使反射波、绕射波等都能够准确归位。这些处理方法在栾川金属矿地震勘探资料处理中取得了不错的效果。

Research on seismic data processing in metal deposits

In allusion to exploration seismic data for seismic signal is very weak，and the noise is very strong characteristics of seismic data in luanchuan seismic exploration project of henan province as an example，studied to improve signal to noise ratio and resolution of seismic data in seismic data processing technology and processes，using the advantage of different processing system module trial and error，determined the final processing parameters，optimizing a set of the refraction static correction-indoor residual static correction for first-break waves-reflection residual static correction of comprehensive static correction technology，to solve the problem of static correction，combined use of multi-domain denoising method to suppress the noise，application of spherical spreading compensation technique to compensate the energy from the vertical，combination of surface consistent amplitude compensation technology of shotpoints and detection points to compensate the transverse energy equilibrium.Using prestack time migration enables reflection，diffraction wave simultaneously.These treatment methods in Luanchuan seismic exploration data processing has achieved good results.
