多波资料处理及解释方法的研究进展

笔者认为,当前多波勘探研究的重点仍然是多波资料的处理和解释问题。文中在常规多波资料处理的基础1]上,展示了笔者近几年在多波资料处理及解释方面研究的新方法、新技术、新成果。内容包括以各向异性介质为基础的裂缝预测成果、速度分析、动校叠加、AVA叠前参数反演成果,以及以深度域成像为基础的深度域多波合成地震记录、层位标定及声阻抗、横波速度等参数反演的成果等。以上成果提高了多波处理及参数反演的精度,开辟了多波解释的途径。

Progress in study of multi-wave data processing and interpretation

The authors consider that the current multi-wave exploration study is still the issues of multi-wave data processing and interpretation. On the basis of ordinary multi-wave data processing 1], the paper showed the new approaches, techniques and results of multi-wave data processing and interpretation studied by the authors in recent years. The contents included fracture-predicted results, velocity analysis, NMO stack and AVA prestack parameter inversion that are on the basis of anisotropic medium as well as multi-wave synthetic seismograph in depth domain, layer calibrating and parameters inversion such as acoustic impedance and S-wave velocity that are on the basis of imaging in depth domain. Above results improved the precision of multi-wave data processing and parameter inversion, opening the way of multi-wave interpretation.
