摘要： A method for detecting the presence of an acid gas in a formation fluid from a subterranean formation comprises (a) lowering a coring assembly into a wellbore. The coring assembly including an outer core barrel and an inner core barrel disposed within the outer core barrel. The inner core barrel has an upper end, a lower end opposite the upper end, and a core sample chamber extending axially from the lower end. In addition, the method comprises (b) capturing a core sample from the subterranean formation within the sample chamber. Further, the method comprises (c) raising the coring assembly to the surface after (b). Still further the method comprises (d) contacting a formation fluid in the sample chamber with at least one detector during (c). Moreover, the method comprises (e) detecting the presence of a formation acid gas in the formation fluid with the at least one detector during (c).
摘要翻译：用于检测来自地下地层的地层流体中酸性气体的存在的方法包括（a）将取芯组件降低到井眼中。所述取芯组件包括设置在所述外芯筒内的外芯筒和内芯筒。内芯筒具有上端，与上端相对的下端，以及从下端轴向延伸的芯试样室。此外，该方法包括（b）从样品室内的地层中捕获核心样品。此外，该方法包括（c）在（b）之后将取芯组件提升到表面。此外，该方法包括（d）在（c）期间使样品室中的地层流体与至少一个检测器接触。此外，该方法包括（e）在（c）期间用至少一个检测器检测地层流体中地层酸性气体的存在。
