航空、航海重力和重力梯度在海洋、未知陆地战略勘探的发展

Development of airborne and marine gravity exploration and gravity gradient strategic exploration for the ocean and unknown land

随着仪器科学的进步和发展,使移动平台式地球物理测量方法成为可能.移动平台式的物探测量作为一种高效的地球物理勘探手段,在地质调查、油气资源勘探和固体矿产资源勘探等相关领域扮演着重要的角色.地形情况良好区域的资源已经探明的情况下,地球物理学家们将眼光着眼于未知陆地和海洋资源,随着国家"十三五计划"的进行,未知陆地和深海资源勘探得到了人们的广泛重视.与此同时,航空、航海重力仪器和重力梯度仪器的发展,使地球物理学家们有了可以应对未知陆地、深海以及深远海资源勘探的重要武器.相比于未知陆地和海洋地震勘探,航空、航海重力和重力梯度数据测量具有快速、稳定、低成本的特征,可以快速圈定异常区域,为进一步更高精度的资源探测提供良好靶区.

With the progress and development of Instrument Sicence, the geophysical measurement with the mobile platform become possible. As an efficient geophysical prospecting method, mobile platform geophysical survey plays an important role in geological survey, oil and gas exploration and solid mineral resources exploration. Good terrain area resources has been proven cases, geophysicists will focus on the vision of the unknown land and marine resources, with the national '13 th Five-Year plan', received widespread attention of the unknown land and deep sea resources exploration. At the same time, the development of aviation, marine gravity instruments and gravity gradiometer enabled geophysicists to have important weapons to deal with unknown land, deep sea and deep sea resources. Compared to the unknown land and marine seismic exploration, navigation, gravity and gravity gradient measurement data is fast, stable and low cost characteristics, can quickly locate the abnormal area, provide a good target for further higher accuracy of resource exploration.
