成像技术在矿区重力勘探中的应用研究
|
摘要
在重力勘探中利用概率成像新方法处理数据,在东北某矿区实测重力剖面数据,在常规处理解释中遇到很多不确定性.而概率成像以及重力梯度概率成像的新方法解决了在实际工作中无法进行场分离的难点,去除干扰场的叠加.通过对比分析更好地处理解释矿区的重力异常,圈定异常地质体,为找矿提供更有力的依据,从而解决了复杂地区重力场的反演解释问题,对重力勘探工作中复杂地区重力异常的解释有很好的利用价值,能快速准确稳定地进行重力异常成像反演.
The method of probability imaging,usually used to process the data in gravity prospecting,however,cannot show good result in the study on a certain mining area in Northeast China. While combining with gravity gradient probability imaging,it can solve the difficulty of field separation and remove the superposition of interference field in practical work. The gravity anomalies in the study area can be well interpreted with delineation of anomalous geological bodies through comparative analysis on vertical and horizontal gradient probability imaging,which can provide a more powerful basis for prospecting and solve the problems of inversion and interpretation of gravitational field in complex areas.
