一、什么是石油地质数据库?我们先从一般数据库谈起。关于数据库(Data base)的概念还没有统一,可以从各种角度下定义。从使用电子计算机技术管理数据的角度讲,数据库是数据的电子存储、传送和检索系统。数据库必须有随机(任意地)存取和更新(更换、插入及抹掉)数据的功能,大型数据库还要有数据通信的能力。石油地质数据库是石油地质资料的电子存储和检索。目前世界上最大的石油地质数据库是美国一加拿大钻井地质数据管理系统,共有100万口以上的钻井的地质数据存入机器外存(磁带、磁盘)。数据库从规模来讲,可以分大、中、小型。本文着重介绍适用于地质实验中心数据
First, what is a petroleum geology database? Let’s start with the general database. The concept of the database (Data base) has not been unified, can be defined from a variety of perspectives. From the perspective of using computer technology to manage data, the database is an electronic storage, delivery and retrieval system for data. Databases must have the ability to randomly (and arbitrarily) access and update (replace, insert, and erase) data, while large databases also have the ability to communicate data. The petroleum geological database is the electronic storage and retrieval of petroleum geological data. At present, the largest petroleum geological database in the world is a US-Canada drilling geological data management system. A total of more than 1 million drilling geological data are stored in the machine’s external memory (tape, disk). From the size of the database, can be divided into large, medium and small. This article highlights the data applicable to the Geological Experiment Center
