Ｃ／Ｏ测井中采用同步测量技术来分析非弹性γ与俘获γ，但在一些ＭＳＩＣ／Ｏ测井中发现非弹性γ的一小部分或一大部分超前于非弹性门而进入俘获门，我们把这一问题叫做“错位”。“错位”使得Ｃ／Ｏ的ＣＩ值不正常，测井曲线不合格。这样的仪器不能用来测井。吉林油田测井公司碳氧比维修班成功地解决了Ｃ／Ｏ仪器“错位”等技术难题，在该油田所使用的ＣＺＦ９０－９４－０９发生器已测井８８口，累计打靶时间２３０ｈ，并且至今完好。这与制造厂产品质量达标分不开，更与现场的使用、维修、保养和改进有关。
In C / O logging, simultaneous measurement techniques are used to analyze inelastic γ and capture γ, but in some MSIC / O logs a fraction or a large portion of the inelastic γ is found to enter the trap gate ahead of the inelastic gate, We call this question “misplaced.” “Dislocation” makes C / O CI value is not normal, logging curve failed. Such instruments can not be used to log well. The C / O ratio maintenance workshop of Jilin Oilfield Logging Company successfully solved the technical problems such as “misalignment” of C / O instruments. The CZF90-94-09 generator used in this field has measured 88 wells and accumulated the shooting time for 230 hours, and So far intact This is consistent with the manufacturer’s product quality standards, but also with the use of the site, repair, maintenance and improvement related.
