摘要
大张坨凝析气藏于1995年开始循环注气开发,在开发过程中有一个重要任务就是动态跟踪与监测,而如何才能监测注气井气源何时到达生产井及气源流向等,成了开发方案执行好坏与监测工作的重点。根据对国内外有关资料的分析,提出了利用示踪剂跟踪流体流动来监测开发方案实施情况的方法,并从注入示踪剂的筛选、注入量的确定、注入的方式及跟踪监测的技术等方面不断完善这一方法,再对大张坨凝析气藏循环注气作业现场情况实时观测,证明示踪剂的跟踪和监测技术对方案调整、指导开发具有重要意义,并可为今后类似开发提供借鉴。
The development of the Dazhangtuo condensate gas reservoir by cyclic gas injection began in 1995. During the program, the performance tracking and monitoring is of great importance. How to monitor the time at which the gas source of injection wells can reach production wells and the direction it will flow decides whether the program could be conducted well or not. According to the data analysis results at home and abroad, the paper presents that tracer can be used in tracking fluid flowing and monitoring program performance. Through the study of tracer screening, injection volume, and injection method, combining with the conducting and monitoring results of the cyclic gas injection in the Dazhangtuo condensate gas reservoir, it is concluded that trace tracking and monitoring plays an important role in program regulating.
