苏联研学院乌拉尔分院矿业研究所Г.М.瓦斯克波依尼柯夫研究了使用选择性γ-γ测井勘探重金属矿床的可能性。他的研究工作表明“可以选择一种γ量子能量的初次射线的源,使其射线在原子序数(Z)较小的介质中强烈的散射,而在原子序数较大的介质中却被充分地吸收。在这种情况下,第二种介质(Z值大的)对第一种介质(Z值小的)来说是数量不大的掺杂物,它将引起散射射线急剧的减少。在勘探重金属矿床时这种特性能够作为在钻井中区分和研究重金属富集带方法的基础。适当地选择下井仪器装置的参数时 Г.М Vaskovskyov, Institute of Mining, Urals Branch, Institute of Soviet Research, has studied the possibility of using a selective γ-γ logging exploration of heavy metal deposits. His research shows that ”the source of the primary ray that can choose a gamma quantum energy makes it scatter strongly in the medium with the smaller atomic number (Z), but is sufficiently enriched in the medium with the larger atomic number In this case, the second medium (a large value of Z) is a small quantity of dopant for the first medium (small value of Z), which causes a sharp decrease in scattered radiation. This feature can be used as a basis for distinguishing and studying heavy metal-rich zones in drilling while exploring heavy metal deposits. When properly selecting the parameters of the downhole tool set
