摘　　要：笔者提出在反演中增加井约束范围来控制井约束的强度,通过设置多种地质体情况以及不同井况下的约束反演来分析井数据对于地质体重力密度反演的约束效果,从而获得更高分辨率的反演结果,利用该方法圈定了山东省某地区的6处铁矿位置。The authors propose to increase the range of well constraints in inversion to control the strength of well constraints.By setting multiple geological body conditions and constraint inversion under different well conditions,the constraint effects of well data on geological body in gravity density inversion has been analyzed,and higher resolution inversion results are obtained.This method was used to delineate six iron ore locations in an area of Shandong Province.
