基于POSC的测井曲线数据存储管理系统

Data Management System of the Well Logging Curves Based on POSC

在基于POSC标准的基础上 ,分析了POSCEPICENTER数据模型 ,对油田中普遍使用的LS716测井大块数据在磁盘和远程自动磁带库之间实现了一体化的数据管理 ,开发了数据加载、数据删除、头信息浏览和曲线回放等功能模块。该系统的特点是 ,管理信息加载到POSC数据仓中 ,而真正的数据体以外部数据文件的形式存放 ,使得大块数据的加载和提取速度大大提高。同时 。

Through analysis of POSC EPICENTER data model based on the POSC, an integrated data management has been implemented from disk to remote automatic tape library on LIS716 bulk data which is widely used in Daqing oil field. The system includes: data loading, data deleting, head information browsing and logging curves displaying modules etc.. The characteristics of this system are that the management information is loaded in POSC data store while the real data body is loaded in the form of external file,which greatly reduces the time of loading and extracting of bulk data. In the mean time, all integrated data management is implemented from data store to remote tape library on LIS716 bulk data.
