节点地震勘探技术发展的系统性思考
Comprehensive view of the development of nodal seismic technology
摘要
Abstract
Nodal seismic data acquisition is a significant transformation in the technical development of seismic prospecting.Due to their multiple advantages and characteristics,nodal seismometers have been widely used in seismic data acquisition,which signifi-cantly improves the adaptability and flexibility of seismic prospecting in complex surface environments such as mountains.This technology reduces the labor intensity and workload of field operation,and it also improves production efficiency and HSE per-formance.However,nodal seismic prospecting still faces a series of challenges.The development of nodal seismic technology indi-cates not only a change in seismic instruments,but also the changes in the way of seismic data acquisition,processing,and utiliza-tion.Nodal seismometers will develop toward the directions of sustained performance optimization,serialization and diversification,integrated observation of multiple physical fields,feasibility for complicated environments,and related supporting equipment.The change from centralized to distributed seismic data acquisition by utilizing nodal seismometers have optimized and altered the workflow and management of field operation.The way of distributed nodal acquisition is evolving towards long-term continuous re-cording,integrated acquisition of active and passive sources,coexistence of dense and sparse acquisition,real-time monitoring and real-time data transmission,automatic node deployment and recovery.Nodal seismic data processing will evolve towards automated processing workflow and intelligent analysis,which would be supported by seismic processing of active-source and passive-source data as well as data of irregular geometry.The innovative incremental data processing and corresponding workflow is a completely new way of processing,which can be carried out using a type of real-time automated processing workflow in some scenarios.Nodal seismic data will be utilized in a diversity of fields and scenarios,including in-depth utilization of ambient noises from passive sources and integrated utilization of signals from active and passive sources,with an integrated software and hardware system for seismic data acquisition,processing and interpretation.Further efforts should focus on three aspects.The first is a system of nodal seismic instruments,acquisition,processing and application.The second is the integrated development of nodal seismic technology and the new generation of information communication technology guided by application scenarios.The third is an open-source ar-chitecture and ecosystem for the application of nodal seismometers and nodal seismic data.关键词
