Design and Implementation of A2 System Regional Center Data Synchronization Scheme

Based on the production data management system of oil, gas and water wells (A2), Changqing Oilfield has developed comprehensive query, big data analysis and other deepening application functions, which play an important supporting role in oil and gas exploration deployment, production dynamic analysis and other work. At present, Changqing A2 Regional Center has many problems in daily production data synchronization, such as long synchronization time, low timeliness, weak verification logic, and data timeliness and accuracy are facing challenges. In view of the above difficulties, this paper designed a new data synchronization scheme and completed the feasibility test of key technical points by analyzing the publish and unlock process of A2 data and the current synchronization logic, and built a full process closed-loop synchronization system of “publish awareness, decentralized synchronization, unlock identification and local update”. Through actual operation, the average data synchronization time was shortened from 83 min to 2 min, and the unlock recognition rate was improved to 100%, which realized the efficient application of A2 production data and boosted the high-quality secondary accelerated development of Changqing Oilfield. At the same time, the scheme has good guidance and reference significance for other oilfield companies that need to build A2 regional data center.
