在南阳地区,用DZ664型基地回放仪作多次叠加,一直是使用双鼓拚带,换鼓、两鼓的半自动对信号及内外转录的转换(见《石油地球物理勘探》1973年第6期第105页)都是自动控制的。但是用笔画记录作监视时(主带除外),换鼓要用人工移动笔头,这不仅给操作员带来了麻烦,移动不准还影响一次监视记录的面貌,为了解决这个问题,我们搞了一个自动移笔装置(图3)。因为校正步进每录完24道一进入25道就要连续跳到1道(见《石油地球物理勘探》
In Nanyang area, the DZ664 base replay instrument was used for multiple overlays, which has been the semi-automatic conversion of signals and internal and external transcriptions using double-drum strapping, drum change and two drums (see “Petroleum Geophysical Prospecting”, 1973, No.6 Page 105) are automatically controlled. However, the use of stroke records for surveillance (except for the main band), drums to manually move the nib, which not only gives the operator trouble, not allowed to move also affect the appearance of a surveillance record, in order to solve this problem, we engage in An automatic transfer device (Figure 3). Because the correction steps into a record of 24 each as long as 25 will continue to jump to 1 (see “Petroleum Geophysical Prospecting”
