摘　　要：随着世界能源需求的日益加大,酸性气藏在整个天然气工业生产中的地位越来越突出。但由于酸性气藏不同于普通天然气藏,其中的H2S和CO2具有强腐蚀性和剧毒性,测量气藏温度压力的难度是可想而知的,气井井筒的压力温度分布计算的精确程度直接影响深层气井产能评价、生产系统动态分析和生产优化。为此,该研究克服了以往文献在此方面的不足,结合酸性气藏特殊的物性参数,对酸性气井井筒温度压力动态分析展开深入研究,编制了相应的计算机软件,计算出的井口温度压力值与实测值误差很小,为生产单位提供了切实可行的方法。With an increasing energy demand in the world, the acidic gas reservoirs are playing a more and more vital role in natural gas industry. However, compared to the common gas reservoirs, the acidic gas reservoirs have H2S and CO2 with strong corrosion and acute toxicity. And it is difficult to measure their temperature and pressure. The exactly calculated pressure and temperature of gas wellbore directly affects the evaluation of deep gas well deliverability, the dynamics analysis of production system as well as the production optimization. Integrated special physical-properties parameter in the acidic gas reservoirs, this paper makes a deep research on wellbore temperature and pressure and compiles a corresponding software. There is a little error between theoretic and actual pressure and temperature. And this research is available.
