γ测井曲线的解释是铀矿勘探工作中一项十分重要的经常性工作。在我国,这项工作至今仍停留在手工解释状态,而国外,自六十年代起就开始采用电子计算机解释。它不仅比手工解释大大提高了效率,而且能得到更接近于矿体实际情况的铀含量分布数据,为进一步利用γ测井资料提供了可能性。当磁带记录的数字自动测井仪开始广泛使用时,它将更充分地发挥出高效率的优越性。为了取得经验,我们用TQ-16算法语言编制了γ总量和γ能谱测井曲线解释程序,在七○九计算机上进行了初步实践。对三个模型井的γ总量、γ能谱测井曲线及三个钻孔约273米γ总量测井曲线和208米γ能谱测井曲线的解释均获得了令人满意的结果。此外,考虑目前我国铀矿勘探中尚无磁带记录的数字自动γ测井仪的现状,我们编制
The interpretation of γ logging curve is a very important regular work in uranium exploration. In our country, this work still remains in the state of manual interpretation till now, and abroad, the interpretation of electronic computers has been used since the 1960s. It not only greatly improves the efficiency compared with the manual interpretation, but also obtains the uranium content distribution data closer to the actual orebody conditions, which provides the possibility to further utilize the γ logging data. When the tape recorder digital automatic logging instrument began to widely used, it will give full play to the superiority of high efficiency. In order to gain experience, we used the TQ-16 algorithm language to compile the interpretation procedures of γ-total and γ-ray logging curves and carried out the initial practice on 1970 computer. Satisfactory results have been obtained for the total amount of γ, the spectrum of γ spectra and the total γ-ray logging curves of about 273 m and the 208 m γ-ray logging curves of the three model wells. In addition, considering the current status of digital automatic γ logging tool that has no tape records in uranium exploration in our country, we have compiled
