由于凝析油气藏相态变化机理特殊，凝析油气井试井分析目前属世界性的试井分析难题，也是试井理论界的研究前沿和攻关方向，若按常规方法开展凝析油气藏试井工作，对获取的测试资料将无法作出正确解释，这种情况已在塔里木盆地牙哈凝析气田高压气井试井中时有发生，使试井成功率受到严重影响,因此迫切需要有针对性的理论研究成果做指导，切实提高凝析油气藏试井工作质量。根据牙哈凝析气田多年来的生产实践，从试井理论、测试工艺、

现场试井实践3方面开展了综合研究，提出了凝析气井“6+1”试井分析方法和改进的“一点法”产能评价技术，并对多层合采气井的动态特征做了理论分析,初步形成了一套适合塔里木盆地高压凝析气藏试井的测试工艺技术和分析解释技术。

The condensate well testing is a currently world wide challenge as its complicated phase behaviour.So it is a cutting edge research direction of the well testing theory and application. Usually the testing data from a condensate well could not be interpreted correctly if only by means of normal well testing analysis model.It already became one of the major problems of those abnormal over pressure condensate wells in Yaha field, Tarim and it seriously affect the successful ratio of well testing job. An applicable solution is urgently required to direct how to improve the quality of condensate well testing. A new integrated well testing analyze method, which named “6+1”,and a modified one point productivity evaluation technology are put forward from many years field experience in Yaha condensate gas reservoir, which includes well testing theory, procedures and in field practice. A theoretically dynamic analysis of the multi-payzone gas well performance is conducted. The presented integrated technology can be used in well testing procedure and analysis and testing data interpretation of Tarim abnormal over pressure condensate gas wells.
