摘　　要：徐深气田火山岩气藏投产后，以单井为主，从气井的日产量范围、稳产能力、稳产方式等三个方面对气井的稳产特征进行了研究。采用二项式产能方程结合压力恢复试井解释，研究了不同渗透率储层内气井产量与地层压力的关系，确定了不同渗透率条件下气井可选择的产量范围；应用二项式产能方程结合物质平衡方程，研究了不同井控动态储量的气井产量与稳产时间的关系，落实了不同储量的气井的稳产能力；通过对气井生产动态特征的分析，对气井进行了分类，研究了不同类型气井的稳产方式；应用不稳定试井技术从井控区域的物性、形态等方面研究了气井稳产的影响因素，评价了不同类型气井的井控区域特征。在上述研究基础上，提出了不同类型气井的合理产量，结合气田用气的季节性特点与各类气井稳产方式，对全气田进行了合理配产，保证了气田的平稳供气。After putting the volcanic gas reservoirs in Xushen Gasfield into production, the stable production charac- teristics of gas wells, mainly single wells, are studied in three aspects respectively： daily production range, stable production capacity, and stable production method. Applying binomial deliverability equation and combining with pressure buildup testing interpretation, this paper studies the relation between production rate from gas wells and for- mation pressure in reservoirs with different permeabilities and determines the optional production rate range for gas wells under the condition of different permeabilities. Applying binomial deliverability equation and combining with material balance equation, the relation between gas well production rate and stable production time in the case of con- trolling dynamic reserves with different wells is studied and the stable production capacity of gas wells with different reserves is ascertained. Through the analysis of production performance characteristics of gas wells, the gas wells are classified into different types and the stable production manner for different types of gas wells is studied （ that is, continuously and intermittently stable production）. Applying transient well test technology, the influencing factors of stable production of gas wells are studied from the aspects of physical property and morphology of well-controlled area and the well-controlled area characteristics of different types of gas wells are evaluated. On the basis of the above mentioned research, the rational production rate of different types of gas wells is proposed. Considering the seasonal feature of gas consumption of the gasfield and the stable production manner of various kinds of gas wells, the rational allocation for the whole gasfield is conducted and the stable gas supply is ensured.
