在地震地质条件复杂地区，用单一的地震方法解决油气地质方面的问题有一定的局限性。若有针对性地使用某些非地震方法后，情况就不一样了。

Seismic energy is disturbed and attenuated seriously under the bad geological conditions for seismic exploration in southern Huanghai basin, and therefore the Meso-Paleozoic wave group of marine reflection seismic cannot be recognized and the seismogram does not meet the requirement for evaluation of pre-Tertiary oil/gas resources in southern Huanghai basin. In May 2006, marine magnetotelluric sounding experiment was carried out and reliable data were acquired.

针对南黄海盆地深层地震地质条件差，地震波受屏蔽，能量严重衰减，在海洋反射地震资料中很难识别反映中-古生界的反射地震波组，不能满足南黄海盆地前第三系油气资源前景评价的需要等问题，于2006年5月，开展了南黄海海域海底大地电磁测深试验，在盆地内五莲斜坡和胶州凹陷区布设了3个海底大地电磁测深点，取得了可靠的海底观测数据。
