Moreover,according to the Poisson equation and the FEM,the authors also computed the residual gravity anomaly caused by the 3-D residual density structure.
本文利用石油钻井资料和重力观测数据,依据Kriging插值及台湾中国石油公司深度 密度经验公式,计算了该地区沉积地层三维密度及剩余密度结构,并依据三维有限元解泊松方程方法,通过求解重力位计算出三维剩余密度体产生的剩余重力异常。
Through introduction on discovery process of Gouxi iron deposit in Cangshan county,it is regarded that residual gravity anomaly is very effective in prospecting deep concealed ore,while the three-component borehole magnetic measurement can effectively guide the layout of drilling projects in order to reduce blindness.
通过介绍苍山县沟西铁矿的发现过程,认为剩余重力异常是寻找深部隐伏铁矿的有效方法,而井中三分量磁测能有效地指导钻探工程的布设,减少盲目性。
