摘要
在提出经改进的有限差分法大地电磁场偏移成像技术基础上,进一步研究并实现了全频段偏移成像技术,使成像信息得到了丰富完善,提高了分辨率并推进到了适用于复杂地电模型和实际资料处理解释的阶段。通过对江苏北部地质构造复杂地区大地电磁测深资料的偏移成像处理和解释,展示了该方法的有效性和实用性。
On the bases of proposed MT migration imaging technique with improved finite difference method, an all-band migration imaging technique is further studied and implemented, by which the imaging information is enriched and integrated, its resolution is improved an the process of application of geoelectric model and practical data processing and interpretation is speeded up. The effectiveness and adaptability of the method are revealed through the migration imaging processing and interpreting MT depth measuring data in Subei complicated geologic structural area.
