地球物理测井的几种方法

Several methods of geophysical logging

在地质勘探中,地球物理测井是由地面物探演变而来的,测井是在钻孔内进行的物探工作。钻孔内有各种岩层和煤层,它们具有不同的地球物理特性,为了研究这些特性,产生了不同的测井方法、探测仪器和解释手段。包括侧向测井、密度测井、中子测井、声波测井等方法,可以确定岩性、划分渗透性岩层,按不同的测井曲线确定不同岩性的岩层。

In the geological exploration, geophysical logging is evolved from ground geophysical prospecting, logging is carried out in the borehole. There are a variety of rock stratum and coal seam in the borehole, they have different geophysics characteristics, in order to study these properties, there exists different logging methods, detection equipment and means of interpretation. Methods of lateral logging, density logging, neutron logging and acoustic logging can determine lithology, divide permeability stratum, and determine different logging curve according to different lithology.
