大庆喇嘛甸地下天然气储气库开发技术研究

A STUDY OF DEVELOPMENT TECHNIQUE OF LAMADIAN UNDERGROUND NATURAL GAS STORAGE IN DAQING

大庆喇嘛甸地下天然气储气库基于大庆喇嘛甸层状砂岩油田的气顶 ,是我国投产最早的地下天然气储气库。二十多年的注采实践证明 :利用地下储气库储采天然气是合理利用天然气资源最有效的手段 ,不仅有效解决了大庆地区冬夏季节用气和因石化厂等用气大户检修停产引起的用气不均问题 ,而且有效地保护了环境。文章回顾了大庆喇嘛甸地下储气库的开发历程及各阶段的主要做法 ,论述了储气库设计及库容量测算技术、注采气系统节点分析方法、动态监测系统及调整技术、地面工艺配套调整技术、动态分析技术和管理方法等一套储气库主要开发技术 ,具有较高的技术和经济价值。

The Lamadian underground natural gas storage in Daqing was constructed on the basis of the gas cap of Lamadian bedded sandstone oil field in Daqing and is one of the earliest one that was put into use in China. Through the practice of gas injection and recovery for over 20 years, it is indicated that the natural gas storage and recovery by utilizing underground gas storage is the most efficient measure for the rational utilization of natural gas resource, which not only effectively solves the problem of non-equilibrium gas consumption due to the difference between summer and winter in Daqing region and due to petrochemical plant's production being held up for repairing equipments, but also effectively protects the environment. In this paper, the development course of the Lamadian underground gas storage in Daqing and the main way of doing in every stage are reviewed and a set of the main development techniques for the gas storage, such as the design of the gas storage, the volume calculation method for the gas injection and recovery system, the monitoring and regulating technique for the dynamic system, the adjusting technique for forming a complete surface technology, the dynamic analysis technique and the management method, etc. are expounded, having a greater technic and economic value.
