基于分布式数据仓库的协同钻井信息共享平台的研究

Research on Information Sharing Platform of Collaborative Drilling Based on Distributed Data Warehouse

针对钻井信息管理和共享中出现的问题,结合数据仓库和Agent技术的优点,介绍采用数据仓库、Agent和计算机网络技术相结合实现信息共享的方法,并在此基础上提出了信息共享平台模型;此模型中,底层数据层采用分布式数据仓库来组织信息;以钻井液为主题,通过维度建模法创建了数据仓库模型,并提出协同查询流程,并通过多个Agent相互协作实现分布在不同地点、不同类型和不同结构信息的管理,同时借助于网络技术来实现对各种钻井信息的共享;结果表明,协同钻井信息共享平台模型的建立,能最大限度的发挥钻井中各种复杂信息的价值,对提高信息的共享度起到重要作用。

Aiming at the sharing issues in the drilling information management, this article introduces a method for realizing information sharing by combining the advantages of data warehouse and agent technology, based on which the information sharing platform model is put forward. In this model, the underlying data layer adopts the distributed data warehouse to organize the information. Taking drilling fluid as subject, firstly the model of DW is set up by dimensional modeling technology, then the procedure of cooperative query has been introduced, finally through the interaction between a number of agents, the management of all kinds of information can be realized that are distributed in different locations, of different types and structures, while all kinds of drilling information can be shared by network technology. The results demonstrate that the establishment of information sharing platform model of collaborative drilling can maximize the value of drilling information and play an important role in improving data sharing degree.
