地球物理数据网格化参数的确定及模型的选择

Determination of Grid Parameters of Geophysical Datas and the Selection of Grid Model

根据地质目标体不同,探测深度不同,物探测网所采用的比例尺不同,相同比例尺测量,由于异常细节差异,点线距不同,使得不同比例尺测网采集同一物探数据,由于网格化差异,异常形态不同。为了尽可能准确体现地下地质体的异常范围、异常形态,正确的选择网格化方法,使后期异常解释更准确,该文介绍了如何正确选择地球物理数据网格化参数的方法。

According to different geological objects and different detecting depths, different scales of geophyical measuring will be chosen. During the same scale measurement, due to the abnormal differences in detail, abnormal shape is not the same when collecting the same geophysical datas with different scales. In order to reflect the abnor- mal range and shape of underground geological bodies as accurately as possible, the grid model will be selected cor- rectly. It will make later anomaly interpretation more accurately. In this paper, how to choose the right parameters of geophysical data has been introduced.
