摘要： 根据渤海西岸和渤海中部两口探井的探测和对比实验分析，利用超长电磁波遥测技术可以根据已知探井的探测对比分析预测新探井的岩性界面，协助井位的选址和设计。另外，利用超长电磁波的探测技术可以从剖面和平面上对远景区进行普查性探测，编制远景区的构造图。根据塘沽-大连探测的超长电磁波频谱曲线剖面对比分析，证实引起渤海中部重磁异常高的地质体可能是基性超基性岩体。渤海中部地区的岩浆活动为本区的有机物成熟提供了热机制，因此，渤海中部地区可能是渤海深层天然气的勘探远景区。

Abstract: On the basis of analysis and comparison between two drills, one in the center of Bohai Sea, another near the west shore of Bohai Sea, ultra-long electromagnetic wave remote sensing can be applied to forecast the interfaces between the different rocks, and help to choose the location of drill and drilling plan. The ultra-long electromagnetic remote sensing also can be applied to general investigation in the prospecting area and organizing the structural map on the basis of the profiles and plane. Based on the analysis of the ultra-long electromagnetic wave curves from Tanggu to Dalian, the geological body to effect the high gravity and magnetic anomalies could be a mafic intrusion. The magma activity provided the heat source to organic maturation in the center of Bohai Sea, so the center of Bohai Sea could be the prospection of deep gas in Bohai Sea.

Key words: ultra-long electromagnetic wave, detecting sea, high gravity and magnetic anomalies, deep petroleum
