摘要
本文介绍一种为油藏描述所设计的建立在VAX-11/780计算机上的网状测井数据库。它是在VAX/VMS操作系统支持下采用网状数据模型,使用数据描述语言(DDL)定义的数据库模式。用DML语言对库进行操作(存储、检索、删除、修改等)。用户可以根据不同需要访问数据库,从库中提取各种数据进而做各种数字处理,用于多种地质目的。该数据库可作为油藏描述综合数据库的一部分,也可独立使用,为测井分析家提供各种测井信息。
A logging network database has been built on the VAX-11/78O compu-ter. It is designed to be used for reservoir description, supported by VAX/VMS operating system, using network data medel. The base schema is de-fined by data tacribing language (DDL). The data manipulation language(DML) is used to operate (store, search, delete, update, etc) the database. Userscan address the database for various purposes, and access to the data fromthe base and perform diffferent data-processing operations for geofogicaluses. This database could ant only be a part of RDS integrated detabase,but also used independently to provide log information for log analysts.
