摘要： 牙哈凝析气田是目前全国最大的采用高压循环注气开发的整装凝析气田。凝析气藏是一种特殊、复杂的气藏，在开采过程中凝析油气体系在地层中的渗流伴随着复杂的相变。与一般气藏相比，凝析气藏中具有许多影响凝析油气渗流的特殊因素,如地层和井简中的流体相变以及地层中油气两相渗流等。因此,凝析气井试井分析有显著的特殊性。围绕凝析气井试井分析的特殊表观现象,以相关基础理论为基础,以解决实际问题的应用研究为目标,在牙哈凝析气田成功地应用了较为完备的凝析气井试井分析技术体系。同时,利用近三年来的多种试井解释成果资料,对该凝析气田的储集层参数、边界识别、气井产能、反凝析的污染效应等进行了分析研究，正确认识了凝析气井及气藏的生产动.态，也为气田下一步开发政策的制定提供了科学依据。

Abstract: Yaha field is the largest integrated condensate gas field developed by the cyclic gas injection with high pressure. The condensate gasreservoir is a special and complex gas reservoir, in which condensate hydrocarbon system flows in strata with complicated phase behaviorchanges during the development, and many specific factors affecting condensate oil-gas fluid flow appear compared to a conventional gas reser-voir, such as phase behav ior change of fluid in strata and wellbore as well as oil and gas two-phase flow in the porous media, etc. So the well testanalysis of condensate gas wells is different from other wells. In light of this speciality, a relatively complete set of well test analysis techniquesfor condensate gas wells is successively applied in Yaha field by means of related basic theories and cases. In addition, using past three-yearwell test interpretation results, the reservoir parameter, boundary identification, gas well productivity and pollution effect caused by retrogradecondensation of this field are analyzed for proper recognition of production performance of the condensate gas wells or reservoirs.
