涪陵页岩气田主要动态监测技术概论

An Overview of the Main Dynamic Monitoring Technologies in the Fuling Shale Gas Field

页岩气井经过大型水力分段压裂改造后,产层缝网发育程度、段簇产气能力不均衡,生产中存在压力递减速度较快、持续返排等特征。为了气田高质量发展,除了完成常规动态监测资料录取外,涪陵页岩气田还优选重点井,持续有效地开展气田动态监测资料专项录取工作,形成了水平井产出剖面测试、压裂裂缝实时监测、井间连通性监测等关键核心技术,为气田生产问题解决、开发规律研究以及开发方案部署提供有力支撑。

After large-scale hydraulic fracturing,shale gas wells exhibit uneven development of fracture networks and clus-ter-based gas production capabilities,characterized by rapid pressure decline and continuous flowback during production.To ensure high-quality development of the gas field,Fuling Shale Gas Field not only completes the acquisition of conventional dynamic monitoring data but also selects key wells for continuous and effective acquisition of specialized dynamic monitoring data.This has led to the formation of key core technologies,such as horizontal well production profile testing,real-time monitoring of fracturing fractures,and inter-well connectivity monitoring,which provide strong support for solving produc-tion issues in the gas field,researching development patterns,and deploying development plans.
