数值试井技术在复杂气井解释中的应用

常规试井技术在均质性油气藏、单相渗流范畴内已较为成熟，而数值试井理论和方法作为一种新技术，实际应用还不多。在简要介绍了数值试井技术的一些特点和使用现状基础上，总结了在靖边气田、榆林气田、乌审旗气田、苏里格气田等不同储层复杂气井的数值试井应用情况，详细描述了采用常规解析试井分析方法和数值试井分析方法的过程，对比分析了两种方法的解释结果，讨论了不同解释方法的特点、效果和使用条件。这对进一步完善试井解释技术、提高试井技术的应用水平和效果、带动数值试井技术的推广和应用有促进作用。

APPLICATION OF NUMERICAL WELL TEST ANALYSIS IN COMPLEX GAS WELLS

Conventional well test analysis has become matured as to application in homogeneous reservoir and single-phase flow, while theories and methods of numerical well test analysis are rarely used as a new technology. In this paper, some features and current applications of numerical well test analysis were briefly introduced, especially applications in complex gas wells in various kinds of reservoir, such as Jingbian, Yulin, Wushenqi, Sulige gas fields. The process of conventional and numerical well test analysis was illustrated in detail with comparison of the analysis results from the two methods. These summaries are very useful to improve application of well test analysis technology and extend application of numerical well test analysis.
