摘要
Expenditure on wells constitute a significant part of the operational costs for a petroleum enterprise, where most of the cost results from drilling. This has prompted drilling departments to continuously look for ways to reduce their drilling costs and be as efficient as possible. A system called the Drilling Comprehensive Information Management and Application System (DCIMAS) is developed and presented here, with an aim at collecting, storing and making full use of the valuable well data and information relating to all drilling activities and operations. The DCIMAS comprises three main parts, including a data collection and transmission system, a data warehouse (DW) management system, and an integrated platform of core applications. With the support of the application platform, the DW management system is introduced, whereby the operation data are captured at well sites and transmitted electronically to a data warehouse via transmission equipment and ETL (extract, transformation and load) tools. With the high quality of the data guaranteed, our central task is to make the best use of the operation data and information for drilling analysis and to provide further information to guide later production stages. Applications have been developed and integrated on a uniform platform to interface directly with different layers of the multi-tier DW. Now, engineers in every department spend less time on data handling and more time on applying technology in their real work with the system.
石油企业运行成本中油井的费用绝大部分源于钻井成本。钻井部门始终在寻求降低成本的方法并有效地加以实施。本文所开发的钻井综合信息管理与应用系统(DCIMAS)就是收集、存储、充分利用有效的井眼数据和所有与钻井实施过程相关信息的平台。它主要由三个部分组成:数据的收集与传输系统、数据仓库管理系统(DW)和核心综合平台。在应用平台的支持下,井场的相关操作数据通过信号发射装置和ETL(提取、转化、装载)工具箱电子信号发射到数据仓库传入数据仓库管理系统。有了高品质的数据,中心任务是要更加充分的利用所有的数据与信息来进行钻井分析和为今后的生产过程提供参考。文章中也描述了钻井信息数据仓库的建立过程。多层数据仓库的各个层集成在一个统一的平台上成为应用系统。该系统应用表明,各部门的工程师们很少花费时间去处理数据,而是在各自的实际工作中更多地应用此项技术。
