摘　　要：“十四五”大庆油田振兴发展进入了新阶段,对海量地震数据规模化处理提出了新要求,地震资料处理迈入了盆地级叠前大数据时代。叠前地震资料大数据质量的好坏关系着偏移成像品质的高低,因此叠前地震资料大数据的精细质控对油田勘探开发高质量发展具有重大意义。由于数据道头信息缺项、归档内容不规范、数据回溯难、数据结构化与文档保存不同步等难题,叠前地震资料的数据质量受到不同程度的影响,无法满足勘探开发高质、高效、全生命周期的生产需求。经过不断地探索与实践,建立了“五化精细质控”,即以质控工作制度化、多级质控流程化、质控评价表单化、质控软件标准化、数据管理信息化为核心的叠前大数据精细质控方法,有效提升了地震数据品质,为地震资料高质量处理保驾护航,实现了叠前地震资料的标准化管理与规范化治理。该方法针对海量地震叠前数据,建立了盆地级地震大数据平台标准化管理与质控,统一了数据规范标准,有效提升了数据质量,完善了质量控制流程、模式,更新了质控标准,有效地支撑勘探开发核心业务的高质量、高效率、规模化发展。The revitalization and development of Daqing oilfield in the 14th Five-Year Plan period has entered a new stage,which puts forward new requirements for large-scale processing of massive seismic data,and seismic data processing has entered the era of basin pre-stack big data.The quality of big data of pre-stack seismic data is related to the quality of migration imaging,so the fine quality control of big data of pre-stack seismic data is of great significance to the high-quality development of oilfield exploration and development.Due to the lack of data track header information,non-standard archiving content,difficult data backtracking,unsynchronized data structuring and document preservation,the data quality of pre-stack seismic data has been affected to different degrees,and cannot meet the production needs of high quality,high efficiency and full life cycle of exploration and development.Through the continuous exploration and practice,the"five aspects of fine quality control"has been established,that is,the pre-stack big data fine quality control method with the institutionalization of quality control work,the processing of multi-level quality control,the unitarization of quality control evaluation form,the standardization of quality control software,and the informationization of data management as the core has effectively improved the quality of seismic data and protected the high-quality processing of seismic data,and thus realized the standardized management and governance of pre-stack seismic data.Aiming at massive pre-stack seismic data,this method establishes standardized management and quality control of basin-level seismic big data platform,unifies data specification standards,effectively improves data quality,perfects quality control process and model,and updates quality control standards,and thus achieve high-quality,efficient and large-scale support for the core business of exploration and development.
