我国目前所使用的煤田测井仪大体分为两类,即补偿式和非补偿式,其中多数是照相式和部分推笔式记录仪。由于煤田测井,在同一个钻孔中同一种参数有几种不同深度比例尺;再加之,目前测井参数不断增加。因此,测井工作量不断增加,占用井场的时间也不断增加,随之增加了发生测井事故的可能性。再者由于幅度的不合适,深度记号的漏记都可能发生,这都直接影响了测井曲线的记录质量。基于以上原因,我们试制了
Coalfield logging tools currently used in our country are generally divided into two categories, that is, compensation and non-compensation, most of which are photographic and some pens. Due to coalfield logging, there are several different depth scales for the same parameter in the same borehole; in addition, the current logging parameters are increasing. As a result, logging workloads continue to increase, and the time it takes to occupy the wellsite is also on the rise, increasing the likelihood of logging accidents. Furthermore, due to the improper amplitude, the missing marks of depth marks may occur, which all directly affect the recording quality of the well logs. Based on the above reasons, we have trial-produced
