对气测录井技术的几点认识

该文首先从全烃检测器的工作原理和分析机理入手,对标定方法进行深入分析,从中找出全烃值小于甲烷或烃组分之和的原因,并发现用混合样标定全烃能降低全烃检测系统检测效率,提出了采用甲烷气样标定的认识。又从气测仪器设计角度分析了全烃与组分检测系统,在气测录井过程中具有分工和相互补充作用,全烃和组分检测系统的最小检测值和检测范围的确定原则,进一步分析用甲烷气样标定的优点。阐明了气测录井中定性与定量分析的相互关系,澄清了气测录井技术中几个模糊的认识。

A Bit of Cognition Upon Gaslogging Technology

Staring with working principle and analysing mechanism of total gas detector,the paper first studies the calibrating methods thoroughly and finds out the reason that total gas value is smaller than methane or the sum of hydrocarbon components.The author has discovered that it may decrease the detecting rate of total gas detecting system to calibrate total gas by using mixed gas sample,points out the cognition of calibrating with methane sample,and then analysing total gas and component detecting system in point of the design of gas instrument,finds both of them have the work division and supplement each other during gaslogging,giving out the determining principle of minimum value and detecting range for total gas and component detecting system.The paper analysis further the advantages of using methane sample for calibration.The author expounded the mutual relations of qualitative and quantitive analyses in the process of gaslogging,clarifying blurred cognitions of gaslogging technology.
