摘　　要：在油气勘探过程中,越来越多的井遇到不同浓度的CO_2和H_2S气体,有些井更是同时含有CO_2和H_2S气体。CO_2含量达到一定比例后,将会起到灭火剂的作用,地层产出的气体将无法点燃。因此,同时含有H_2S和CO_2的气井要比只含H_2S的气井测试施工难度大、危险性要高,需要采用全套防硫测试流程和设备,同时加强安全措施,优化施工工艺。During the exploration process of oil and gas,more and more wells are encountered different content of CO_2 and H_2S gases,and some wells contain both CO_2 and H_2S at the same time. When reaching a certain proportion of CO_2 content,it will play the role of fire extinguishing agent to make the gas produced from the formation not to be ignited. Therefore,well test operation to the gas wells containing both CO_2 and H_2S are more difficult and dangerous than that of containing H_2S only,and are necessary to adopt a full set of anti-sulfur testing process and equipment while strengthening safety measures and optimizing construction technology.
