本研究探讨了实施原位二氧化碳回收封存的可行性，该方案是马来西亚某气田的一项切实可行的开发策略，该气田的初始二氧化碳含量约为60%。通过对关键气田参数的全面分析，本研究旨在优化累计产气量，同时有效管理二氧化碳封存。本研究构建了一个稳健的组分动力学模型。该模型有助于在产气井和注入井之间回收产出的二氧化碳，同时，在每口井中引入二氧化碳示踪剂，可以区分二氧化碳来源，从而改进停产策略并优化参数。
本次可行性研究的重点是处于开发前期的海上气田。地质解释表明，该气田主要为滨岸沉积环境。
This study explores the feasibility of implementing in-situ CO2 recycling for sequestration as a fit-for-purpose developmental strategy for a Malaysian gas field characterized by an initial CO2 content of approximately 60%. Through a comprehensive analysis encompassing key field parameters, the study aims to optimize cumulative gas production while effectively managing CO2 storage. A robust compositional dynamic model is constructed. The model facilitates the recycling of produced CO2 between gas producers and CO2 injectors, while the introduction of CO2 tracers for each well enables the differentiation of CO2 sources, enhancing shutdown strategies and parameter optimization.
The focus of this feasibility study is an offshore gas field in a predevelopment stage. The geological interpretation suggests a predominantly shoreface depositional environment.
