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
根據渤海西岸和渤海中部兩口探井的探測和對比實驗分析，利用超長電磁波遙測技術可以根據已知探井的探測對比分析預測新探井的巖性界面，協助井位的選址和設計。另外，利用超長電磁波的探測技術可以從剖面和平面上對遠景區進行普查性探測，編制遠景區的構造圖。根據塘沽-大連探測的超長電磁波頻譜曲線剖面對比分析，證實引起渤海中部重磁異常高的地質體可能是基性超基性巖體。 -
