钻孔地球物理方法(俗称测井)已经历了半个世纪的发展,它在油田和煤田普查勘探中已进入数字化时代,即电子计算机的应用已获得推广。在地质构造较复杂,物性变化急剧的金属矿床上则较滞后,但也有其独到之处,在普查勘探金属矿床的各个阶段,钻孔地球物理方法不仅用来研究井壁地质问题,近廿年来还发展了一系列探测井周盲矿 Drilling geophysical methods (commonly known as logging) has gone through half a century of development. It has entered the digital era in census and exploration of oilfields and coalfields. The application of computer has been popularized. In the complex geological structure, rapid changes in properties of metal deposits on the lag, but also has its unique features in the census of the various stages of exploration of metal deposits, drilling geophysical methods not only used to study borehole geological problems, the past 20 years A series of blind wells have also been developed
