摘要(Abstract)：

徐深气田开采层位为火山岩储层,受构造和火山活动的双重控制,非均质性强,连通性差,而且有边底水,现有的经验难以满足开发需要。目前徐深气田已投入开发,如何确保火山岩储层气藏高效开发,首先要解决气井合理产量确定问题。针对徐深气田火山岩储层的特点,对不同类型的气井开展试井工作,利用试井成果确定气井的产能方程。在实际工作中采用了一点法、系统试井、修正等时试井3种方法确定了各类气井的产能方程,气井的产能方程反映了气井的渗流特点。徐深气田火山岩储层气井在生产上表现为产气量差别大、井井产水、压力下降快慢不同,因此,在单井合理产量模式确定上,主要是以气井产能方程为基础,考虑气井的边底水特征、井筒积液、稳产期等因素,对不同类型的气井分别建立了合理产量模式。
Production horizon of Xushen gas field is mainly volcanic reservoir,controlled by structure and volcanicity,presenting heavy heterogeneity and poor connectivity,and with existence of edge and bottom water,in terms of the above situation,the experiences acquired are far behind the exploitation needs.How to effectively proceed development work in volcanic gas reservoir requires initially the identification of reasonable gas well production.Well testing was carried out in gas wells of different types,the results of which helped to confirm production equation.One point method,systematic well tests and modified isochronal well tests to ensure the productivity equation are adopted during practical operation.Gas well productivity reflects the character of seepage.The volcanic reservoir of Xushen represents the differences in gas production, water production in all wells and pressure decrease.Therefore to resolve the problem of setting up reasonable single well production pattern,gas well production equation should be taken into consideration,as well as the character of edge and bottom water,welllbore liquid,stable period and so on,in order to fit for gas wells of different types.
