双色谱气测录井及其影响因素探讨

On dual chromatogram unit gas logging method and its affected factors

为消除钻井液对气测录井的影响 ,提出了一种新型的气测录井方法———双色谱气测录井。和以往的录井方法不同 ,它采用了入口、出口色谱仪进行气测录井。文章阐述了双色谱气测录井的原理 ,并对其影响因素及修正方法进行了分析 ,以期能有效消除钻井液背景气的影响 ,真实地反映地层的气体含量 ,提高气测录井的真实性和可靠性。

In order to eliminate the mud effects on gas logging, this paper puts forward dual chromatogram units gas logging. This method adopts in and out chromatogram units to performance the logging. The paper analyszes the principle of dual chromatogram unit gas logging and its affected factors, and also gives the correcting methods to eliminate the influence of mud background gas.
