PB级地震勘探数据的质控与管理

Quality control and management of PB-level seismic exploration data

现今的地球物理勘探观测精度要求越来越高,采集数据动辄达PB级,如何对PB级的海量数据进行质控与管理成为了新的挑战。本文提出了地震采集实时质量控制(RTQC,Real Time QC)、模块流程化工序、软件实现等方法。该方法在中东某20万道级数字检波器三维项目中成功应用,通过实际验证和基础数据分析证明了该质控与管理方法的实用性,为类似地震勘探项目PB级地震数据的数据管理提供了可借鉴思路。

Nowadays,the geophysical exploration observation accuracy requirements are getting higher,and the acquisition data can easily reach PB(petabyte)-level,so how to quality control and manage the PB-level of massive data becomes a new challenge.In this paper,we propose a real-time quality control(RTQC,Real Time QC)for seismic acquisition,a modular process,and a software implementation.The method is successfully applied in a 200,000-channel digital geophone 3 D project in the Middle East.The practicality of the QC and management method is proved through actual validation and basic data analysis,which provides a reference idea for data management of PB-level seismic data in similar seismic exploration projects.
