井间示踪监测技术在京617井组中的应用

Application of Interwell Tracer Monitoring Technology in Jing 617 Well Group

京11断块自1979年投入开发以来,通过实施同期注水、细分层系调整和稳油控水,断块取得了较好的开发效果。经过三十多年的开发,油田开发难度越来越大,主要体现在压力分布严重不均衡、高含水期注水效率偏低、层系间窜通严重、产量递减快、剩余油分布复杂等。寻找新的监测手段,对油藏进行动态精细描述,是解决上述问题的有效途径之一。井间示踪监测技术是近年来在监测油田生产中,应用比较广泛的一项新技术。

Since the development of Jing 11 fault block in 1979,good development results have been achieved through the implementation of simultaneous water injection,adjustment of subdivision strata and oil stabilization and water control.After more than 30 years of development,oilfield development is becoming more and more difficult,which is mainly reflected in the serious imbalance of pressure distribution,low water injection efficiency in high water cut period,serious interlayer channeling,rapid production decline,and complex distribution of remaining oil.It is one of the effective ways to solve the above problems to find new monitoring means and to accurately describe reservoir dynamics.Interwell tracer monitoring technology is a new technology widely used in monitoring oil field production in recent years.
