二氧化碳海上封存与驱油方案的研究及经济性分析

Research and economic analysis of CO2 offshore storage and EOR schemes

进行二氧化碳地质封存或用于驱油实现部分封存,是减少温室气体排放的有效手段之一。为了对油气处理厂产生的高浓度二氧化碳气源进行封存,对附近海域封存构造、海上驱油油田的适宜性进行分析,选择确定了目标封存地和目标油气田,并对其封存方案、驱油方案进行了研究,对方案的经济性进行了分析。

Geologically storing carbon dioxide or partially storing carbon dioxide for enhanced oil recovery(EOR)are effective means to reduce greenhouse gas emissions.Aiming at storing high-concentration carbon dioxide gas source generated by an offshore oil and gas processing plant,the suitability analysis on offshore storage structure and offshore EOR oilfield are performed,the target storage location and target oil/gas fields are selected and determined,and the storage and EOR schemes are studied,the economy of the schemes is analyzed.
