Abstract: Based on independent research and development, independent design, independent construction, and independent operation and maintenance, Jilin Oilfield established the simple and applicable cost-effective Internet of things (IoT) with the experience that could be duplicated and extended. A series of featured products were innovated and developed, such as the pumping unit shutdown alarm, the oil well measurement and control instrument, and the well site electronic eye. They helped solve some actual production problems, such as the difficulties to find abnormal shutdown and abnormal well conditions as well as the difficult for well site inspection. Those products not only have a reliable performance but also one third of the cost as compared to the equipment of the same kind. Based on integrated application of a number of technologies, the labor strength of supervisors was lowered by more than 85 percent while the supervision efficiency was improved by five times. All the efforts aimed at optimize the IoT system configuration, bring about cloud deployment of servers, cut down the quantity of IoT parts on the well site, reduce the technological difficulty for front-end equipment, change the transmission method, simplify the system structure and ensure a high online rate. The oilfield also tapped big data of IoT and developed the series of technology for in-depth application of electrical parameters, thus making remarkable achievements in diagnosis of well conditions and energy saving. It established the unified cloud platform and brought the whole oilfield under one set of systems, namely one platform,to facilitate software deployment, upgrading and daily maintenance and complete a cost-effective construction, operation and maintenance model. The oilfield promoted transformation of the management process on the basis of digital mindset, adopted the closed-loop management over the whole life cycle of data application and established the new model for the oil production plants to bring oil and water wells under direct and concentrated management.
