Research And Implementation Of Mobile Synchronization Replication Mechanism For Oilfield Well Completion Business

The well completion is the whole process from the beginning of drilling operation to the end of the production operation, its business involves multiple departments. The efficiency and the quality of completion of mobile services directly affect the oil capacity planning, related to the economic benefit of oilfield, and has important research and application value.For the localization operations of well completion business data lending to data inconsistency, this paper proposes a kind of mobile synchronous replication mechanism based on operation log. The client builds log result sets through the analysis of transaction operation sequence, while the server using the client upload the pretreatment result set of the completes data update and generates new result set transaction sequence; the client using the transaction sequence result sets returned from the server updates the local copy data. The process achieves the synchronous replication of the local data and center data, ensures the consistence between the data. For the timeout or failure problem of the mobile transaction access, the paper puts forward a kind of mobile transaction processing mechanism based on improved O2PC-MT. That effectively eliminates the influence of long transaction completion mobile synchronization system on the well completion performance as a whole and reduces the mortality rate of mobile transactions, improves the efficiency of synchronous access,to introduce the mobile transaction processing mechanism and mobile transaction coordination, participate in the nodes, by the analysis of O2PC-MT model.The article research results are applied in practical work in the oil production plant, to achieve the completion of mobile synchronization system. That provides the mobile service platform in real time for oilfield completion management, to improve the agility and management. It has very vital significance to promote the construction of produtivity plan and the digital of oilfield.
