增油与降碳一举两得

Core Viewpoint - The largest carbon capture, utilization, and storage (CCUS) project in the Beijing-Tianjin-Hebei region has injected a total of 300,000 tons of carbon dioxide since its initiation, contributing to both oil production and carbon reduction efforts, equivalent to planting approximately 2.48 million trees [1] Group 1: Project Overview - The CCUS pilot project at the Bailing West potential mountain oil reservoir aims to enhance oil recovery while achieving carbon reduction [1] - The project has been operational since the end of 2022 and is expected to continue until December 27, 2025 [1] - The oil reservoir has a high water cut of 90%, making traditional recovery methods less effective [1] Group 2: Technical Innovations - The project utilizes supercritical carbon dioxide to improve oil recovery by accessing oil trapped in small fractures and low-permeability rocks, potentially increasing oil recovery rates by 27% [2] - A new injection and extraction model has been developed, focusing on injecting gas at the top and extracting oil from lower sections, enhancing recovery efficiency [2] - A digital dynamic model has been created to accurately track fluid movements underground, improving extraction outcomes [2] Group 3: Environmental Impact and Future Plans - The project has optimized a system to recover and reinject carbon dioxide that escapes during oil extraction, aiming for a nearly 100% storage rate [3] - The daily oil production capacity in the CCUS application area has increased from 15 tons to 112 tons [3] - The project plans to sequester 8.47 million tons of carbon dioxide and increase oil production by over 3 million tons, with a carbon reduction effect equivalent to 70 million trees or 5 million compact cars being off the road for a year [3] - The success of the Bailing West CCUS pilot project provides a replicable model for other aging oil fields in China [3]
