Design and implementation of the overall architecture of the Puguang intelligent gas-field project

Abstract

During the development and construction of the Puguang Gas Field, Sichuan Basin, an advanced automatic control system and a fully covered industrial Internet of Things were built. In order to further increase its development benefit, the Puguang Gas Field started the construction of an intelligent gas-field project in 2013. However, there are not mature models and construction standards of intelligent oil and gas fields at home and abroad for reference. In this paper, an overall architecture design of intelligent gas field and its technical and business architecture design were demonstrated according to the principle of “overall planning, step-by-step implementation, response in each step and stressing the main points”, and based on the mainstream design concept and practical experience of intelligentization. Then, combined with the key business target and implementation principle of the gas field, it was conducted and applied. And the following research results were obtained. First, the overall architecture of the intelligent gas field project includes a platform, two centers and two systems, i.e., integrated coordinated application platform, resource sharing center, intelligently assistant decision-making direction center, standard specification system and information safety system. Second, the technical architecture consists of four layers, i.e., industrial Internet of Things + equipment perception introducing layer, infrastructure cloud service layer, platform cloud service layer and software cloud service layer. Third, the business architecture is designed focusing on four support units, including exploration and development management of the gas field, production and emergency direction management of gas field, QHSE management of gas field and business management of the gas field. Fourth, the construction of the intelligent gas field project creates four abilities, i.e., assistant exploration and development decision-marking ability, production optimization and coordination ability, safety control and treatment ability and refined business management ability, to support the smooth operation, efficient management and safe production of the Puguang Gas Field. In conclusion, the intelligent management and decision-making system with the resource sharing center as the base, the integrated platform as the core and two systems as the guarantee has been preliminarily built in the Puguang Gas Field.
