陆地及毗邻海域重力布格校正技术

Bouguer gravity correction for land and TZ

随着重力勘探由陆地向水域、海洋的延伸,对于不同区域、不同勘探条件下采集的重力数据进行布格校正,要求基于统一的高程基准点。故此,将陆地、海洋区域的高程基准点统一到同一位置,采取分层方式进行布格校正,并将海洋区、浅海区的布格重力异常与陆地布格重力异常进行拼接,由此得到全区的布格重力数据,用于重力资料的处理和地质解释。

Since gravity surveys extend gradually from terrene to shallow waters and offshore,so gravity data come from different areas and different conditions.TZ gravity data should adopt a uniform datum.For TZ gravity data,we first conduct Bouguer correction for every layer,and then we merge all gravity data.So all TZ gravity data are corrected to a common level.The merged data is prepared for data processing and interpretation.
