京津冀最大规模CCUS项目“吃”碳又“吐”油

Core Insights - The project is the largest CCUS initiative in the Beijing-Tianjin-Hebei region, having injected over 200,000 tons of carbon dioxide to date [1][2] - The project aims to enhance oil recovery from aging oil fields while promoting green and low-carbon development in line with the "dual carbon" goals [1] Group 1: Project Overview - The CCUS project involves the injection of carbon dioxide into the Bailing West potential mountain oil reservoir, which has been a major oil-producing area for North China Oilfield [1] - The project is designed to include three gas injection wells, twenty oil production wells, and two observation wells, divided into gas injection and carbon storage phases [2] Group 2: Technical Achievements - The project has transitioned from single well testing to overall gas injection at the station, achieving an oil production rate of 40 tons per day [2] - The CCUS initiative has demonstrated a 20% increase in oil recovery efficiency compared to conventional gas injection methods, providing a new pathway for enhancing production in aging oil fields [1] Group 3: Future Plans - By 2025, the project plans to inject 150,000 tons of carbon dioxide, with a total injection target of 12.5 million tons, storage of 8.47 million tons, and oil production of 3.16 million tons throughout the entire testing cycle [2]
