摘要：在凝新气藏循环注气驱替过程中，受储集层非均质性影响，注入的干气客易高渗通道或天然裂缝突进，影响凝析气藏开发效聚。研究凝析气藏注气气审特征，建立凝析气藏注气气审识别评价体系对改善开发效果和提高油气采收率具有重要意义。目前国内外凝析气并气审判别方法主要有现场经验法、图版法、示除剂法、微地震监测法等，针对凝析气减循环注气生产过程中的气审参数变化特征，综合利用上述方法对气审情况进行评价，形成了整析气藏注气气审量化评价体系。以某装析气藏一口实际并为例，对该并的气审情况进行评价，结聚显示该并生产状况良好，未发生气审，与现场实际情况相符。该凝析气藏注气气审量化评价体系为装析气藏的开发部署、优化与气审防治提供了理论依据。

Abstract: When cyclic gas injection is conducted in a condensate gas reservoir, the injected dry gas tends to break through along high-permeability pathways or natural fractures due to reservoir heterogeneity, and consequently its development effect is impacted. To improve the development effect and increase the hydrocarbon recovery fiactor, it is of great significance to investigate the gas channeling characteristics of injected gas in condensate gas reservoirs and establish the gas channeling identification and evaluation system for the injected gas in condensate gas reservoirs. At present, the gas channeling discrimination methods for condensate gas wells at home and abroad include field experience method, chart method, tracer method, microseismic monitoring method and so on. Based on thc variation characteristics of gas channeling parameters during the production of condensate gas reservoir by the cyelic gas injection, the gas channeling was evaluated using above methods comprehensively, and the quantitative evaluation system for the gas channeling of injected gas in condensate gas reservoirs was established. Then, one actual well in a certain condensate gas reservoir was taken as thc
