Gas chromatography of gas samples of the KTB main hole HB1i

The main objective of this drilling fluid analysis was the detection of inflows of formation fluids. Therefore different gases dissolved in the drilling mud were measured continuously and automatically at drill site with three different methodes (Fig.: KTB-Report 92-2 page C13). The operation principles of the mass spectrometer and the gaschromatograph have been explained by STROH et al. (1988) and FIGGEMEIER et al. (1991). The principle of radon determination is published by ERZINGER et al. (1992).

本次钻井液分析的核心目标为检测地层流体溢流。为此，研究团队在钻井现场采用三种不同方法，对钻井泥浆中溶解的各类气体开展连续自动监测（图表来源：KTB-Report 92-2第C13页）。质谱仪（mass spectrometer）与气相色谱仪（gas chromatograph）的工作原理已由STROH等人（1988）及FIGGEMEIER等人（1991）予以阐述。氡气测定的相关原理则由ERZINGER等人（1992）公开发表。
