摘　　要：结合金山地区某高含二氧化碳气井试气进行了有益的探索,通过与常规烃类气井测试相比较,总结出常规测试工艺存在的不足,全面阐述了二氧化碳气井测试工艺的特殊性。通过相关资料及现场应用总结出直接采取流量计孔板的一次节流工艺,有效解决了地面管线由于节流降温所造成的结霜和冰堵难题,确保了测试资料录取的准确性和稳定性,同时也提出了现场测试中所存在的问题和注意事项,力图使这些经验和方法能够更好的应用于现场,为以后二氧化碳气井的测试实践有所帮助并起到指导作用。Combined well testing with high CO_2 content gas in Jinshan district,the beneficial exploration is carried on,and by contrast to the conventional hydrocarbon gas well testing,the deficiencies of conventional test process is summed up and the particularity of CO_2 gas well testing technology is fully illustrated.Through relevant information and field application,one throttle process using flow-meter orifice plate directly is summarized to effectively solute the frost and ice blocking problem caused by the downflow temperature of the surface line,to ensure the accuracy and stability of the admission to the test data,and the existing problems and the matters needing attention in the field test is also put forward,trying to make the experience and method can better be applied in the field,which has practical help and guidance for test in the carbon dioxide gas well.
