地球物理勘探是近代地质勘探中的有效手段,是使地质工作达到多快好省的先进工具。根据几年来石油勘探的情况来看,物探工作至少能起十大作用,即能有效地反映十个基本地质现象。1.走向——准确地确定地质构造或岩体的走向,对于大地构造的分区具有甚为重要的意义。在一般情况下,各种物探的轴向往往是反映了地质构造或岩体的走向。因此,我们根据重力、航磁和电法等资料,肯定了某凹陷具有近似北北东的走向,
Geophysical prospecting is an effective tool in modern geological exploration and is an advanced tool to make geology work faster and better. According to the situation of oil exploration over the past few years, geophysical work can play at least ten major roles, that is, it can effectively reflect ten basic geological phenomena. 1. Going - Accurately determining the direction of the geological structure or rock mass is of great importance to the subdivision of the tectonic setting. Under normal circumstances, the geophysical prospect usually reflects the geological structure or the direction of rock mass. Therefore, based on the data of gravitation, aeromagnetic and electrical method, we affirm that a certain depression has an approximate north-north-east direction,
