钻井工程数据库的研究和设计

Research and Design of Drilling Engineering Database

随着钻井技术和信息技术的飞速发展,科学合理地利用钻井信息对钻井工程管理和决策起着越来越重要的作用。建立一个全面、合理、详细、标准的钻井工程数据库是高效应用钻井信息的关键。在对钻井工程数据库的需求进行详细分析的基础上,通过概念设计、逻辑设计和物理设计3个阶段分析并设计了钻井工程数据库。设计的钻井工程数据库是钻井工程设计和工艺软件的数据存储和管理的基础,支持该软件所有的计算分析模块,达到了各计算模块之间数据共享和减少重复录入的目的;设计的钻井工程数据库符合钻井业务流程、内容全面详实、性能高效、表结构优化、具有良好的可扩展性。统一的钻井工程数据库的建立使海量钻井数据的有效存储成为可能,为进一步的钻井数据挖掘和分析奠定基础。

With the rapid development of drilling techniques and information techniques,effective and rational use of drilling information played a more and more important role in drilling engineering management and strategic decision.Building an overall,rational detailed and standard drilling engineering database was critical for a high efficient application of drilling data.Based on the detail analysis of drilling database requirements,the drilling database was analyzed and designed by conceptual design,logical design and physical design.The designed drilling database was the data storage and management basis for drilling engineering design and technical software;it supported all the calculation modules of the software and reaches the goal of data sharing between the modules.The designed drilling database conformed to the flow process of drilling operations,it had comprehensive and detailed content and high performance and refined structure of data table with good expansion property.The construction of unified drilling engineering database enables the efficient storage of massive drilling data and it provides a basis for further data mining and analysis of drilling data.
