Abstract

Abstract:

Carbon capture, utilization and storage, or CCUS, is one of the key technologies to deal with global climate change, among which CO₂-EOR is an important part. In order to effectively solve the problems that caused by the high cost and low oil price on CO₂ flooding, and promote the large-scale popularization and application of CCUS project, Jiangsu Huayang Liquid Carbon Co., LTD. of Sinopec East China Petroleum Bureau strengthen the integration of the advanced information of carbon dioxide transportation or oil displacement and the production management according to the template of digital oil and gas field construction and in accordance with the working idea of “production automation, safety interlock, unmanned on site and centralized management”. Through the construction and operation of safety monitoring system and information remote control platform, the digital management of CO₂ transportation system, injection system and production area security system is realized, which ensure the safety standard of carbon dioxide transportation, intelligent and efficient oil displacement site and effective supervision in production area. The exploration and practice of digital management transformation of distributed CO₂-EOR project have been completed. By this systematic digital construction, the lowest comprehensive cost and the best security guarantee of CO₂-EOR has been achieved, which is of great significance to the large-scale popularization and application of CCUS project.

Key words: CO₂-EOR, information construction, centralized management, low-cost service, transformation and upgrading
