【摘要】：完井是从钻井作业开始到投产作业结束的整个过程,其业务涉及到多个部门。完井移动服务的效率与质量直接影响油田的产能计划,关系到油田的经济效益,具有重要的研究和应用价值。针对完井业务移动管理导致的数据不一致问题,提出了一种基于操作日志的移动同步复制机制。该机制通过操作日志实现了数据的变化捕获,首先,移动客户端生成操作日志结果集并上载到同步服务器;其次,同步服务器利用操作日志结果集同步更新中心数据库,并生成事务序列结果集回传移动客户端;最后,移动客户端利用事务序列结果集更新本地数据副本。最终实现了移动数据副本与完井中心数据库的同步更新,保证了两者数据的一致性。针对移动事务访问超时或者失败问题,提出一种基于改进O2PC-MT的移动事务处理机制。通过对O2PC-MT模型的分析,引入移动事务处理机制及移动事务协调者节点和参与者节点,有效消除了长事务对完井移动同步系统整体性能的影响,降低了移动事务的夭折率,提高了移动事务处理的效率。将本文研究成果在采油厂实际工作中进行应用,实现了完井移动同步系统,为油田完井管理提供了实时化的移动服务平台,提高了完井管理的敏捷性,对促进油田产能及数字化建设有着十分重要的意义。
[Abstract]:Completion is the whole process from the beginning of drilling operation to the end of production operation, and its business involves many departments. The efficiency and quality of completion moving service directly affect the productivity planning of oil field and affect the economic benefit of oil field. It has important research and application value. A mobile synchronous replication mechanism based on operation log is proposed to solve the data inconsistency caused by well completion mobile management. Firstly, the mobile client generates the result set of the operation log and uploads it to the synchronization server; secondly, the synchronization server synchronizes and updates the central database by using the operation log result set. Finally, the mobile client updates the local data copy by using the transaction sequence result set. Finally, the synchronous updating of the mobile data copy and the completion center database is realized, which ensures the consistency of the two data. A mobile transaction processing mechanism based on improved O2PC-MT is proposed for mobile transaction access timeout or failure. Through the analysis of O2PC-MT model, the mechanism of mobile transaction processing and the nodes of mobile transaction coordinator and participant are introduced, which effectively eliminates the influence of long transaction on the overall performance of completion mobile synchronization system, and reduces the abortive rate of mobile transaction. The efficiency of mobile transaction processing is improved. The research results of this paper are applied in the actual work of oil production plant, and the completion mobile synchronization system is realized, which provides a real-time mobile service platform for oil field completion management, and improves the agility of completion management. It is of great significance to promote oilfield productivity and digital construction.
