摘　　要：塔里木盆地目前已发现凝析气田７个，凝析气藏２８个。截至１９９６年底，对凝析气储层及相近特征流体的储层已完成测试１３９井次，取得了大量的凝析气井试井资料，形成一套适合于塔里木特殊地质条件的试井管柱、试井设计及试井方法。针对塔里木盆地超深凝析气井具有井深、高压、高产高温等特点，通过对大量试井资料的分析、研究，提出了适合塔里木特点的深井凝析气井试井管柱、试井设计原则以及试井方法的优选准则；对不同类型的气井，提出了估算试井时间的方法，提出了确定设计参数的具体方法和要求。提出的方法在塔里木油气区凝析气井试井中得到广泛的应用，取得了很好的效果，方法可靠、适用性强。Seven condensate gas fields and twenty eight condensate gas reservoirs have been found at present in Talimu Basin. By the end of 1996, the well testings of 139 well times had been finished in the condensate reservoirs and the reservoirs containing approximate fluids and a great number of well testing data on the condensate wells had been achieved, thus forming a set of the well testing pipe strings, designs and methods suitable to the special geological conditions in Talimu Basin. In accordance with that the ultradeep condensate gas wells in Talimu Basin are of the properties of a large depth, high formation pressure, high geotherm and high production, the standards of optimizing the well testing pipe string, design and method suitable to the deep condensate gas wells in Talimu Basin are proposed through the analysis and research on the numerous well testing data; the method of estimating well testing time and the method and requirements of determining design parameters are also proposed for various types of gas wells. These methods put forward were widely applied to the well testings in the condensate gas wells in the hydrocarbon bearing regions in Talimu Basin, good results being achieved. These methods are reliable, being of a large adoptability.
