磁力勘探

重、磁力勘探在盆地早期的石油勘探中发挥过重要作用。

Gravitational and magnetic prospecting method has played an important role in early basin prospecting of oil exploration .

进入21世纪后，海域天然气水合物地球物理勘探取得了较大的进步。主要表现为，在勘探技术上已由单一的地震勘探发展到以地震勘探为主，重力、磁力勘探综合应用的格局；

In the 21st century , geophysical exploration for marine gas hydrate has turned from single seismic behavior to integrated gravitational and magnetic way with seismic exploration as the main method .

对于重磁力三维勘探而言，数据采集、地形改正和三维正反演法已逐步走向实用；

So far as 3D gravity and magnetic survey is concerned , the data acquisition , topographic correction and 3D forward and inversion methods are gradually practical ;
