页岩气田智能化生产辅助决策系统应用效果评价

Evaluation of application effect of an intelligent production assistant decision system for shale gas field

页岩气的成功开发,有效推动了中国能源结构优化,但在页岩气井生产规律、合理生产制度、现场管理等方面,传统的人工+计算机模式已无法满足同步跟踪分析及精细气藏管理的需要,且国内外尚无成熟的理论、技术和经验供借鉴。为实现异常的快速反应、气藏的高效管理,在涪陵页岩气田的开发过程中,同步启动了生产辅助决策系统的开发与建设工作。从低压、积液、生产制度变化等方向开展了预警研究,并对单井的生产规律变化进行短期、中期、长期分析与预测,实现了数据变信息,信息促决策的智能化管理目标,有效支撑了页岩气田现场管理,并保障了涪陵页岩气田持续稳产。涪陵页岩气田率先探索的页岩气田智能化建设及应用,为我国页岩气精细化气藏管理奠定了良好基础,具有重要的参考价值和推广应用前景。

The successful development of shale gas has effectively promoted the optimization of China’s energy structure.However,in terms of shale gas well production rules,reasonable production systems and on-site management,the traditional manual and computer operating mode can no longer meet the needs of simultaneous tracking analysis and fine gas reservoir management.Meanwhile,there is no mature theory,technology and experience for reference at home and abroad.In order to achieve rapid response for abnormal situation and efficient management of gas reservoirs,the development of the production auxiliary decision-making system has been initiated simultaneously during the development of Fuling Shale Gas Field.The early warning research has been carried out from the direction of low pressure,liquid loading,production system changes,etc.,and the shortterm,mid-term and long-term analysis and the prediction of production decreasing trend of a single well have been carried out either.The management goal to obtain useful information by data mining for decision-making promotion is realized.This system effectively supports the on-site management of the shale gas field and ensured the continued stable production of the shale gas wells in Fuling Shale Gas Field.The intelligent construction and application of shale gas fields pioneered in Fuling Shale Gas Field has laid a good foundation for the refined management of shale gas reservoirs in China,and has important reference value and application prospects.
