摘要： 针对不同碳源捕集能耗、不同运输地貌和距离的压缩功耗，以及CO2驱不同开发阶段能耗和泄漏的差异，以CCUS项目能耗和泄漏、散逸排放为约束条件，项目周期全流程净减排量最大为优化目标，建立碳减排量核算约束下符合油藏动态开发规律的CCUS源汇匹配方法，可为“双碳”目标下CCUS技术产业布局和项目实施提供决策依据。以中国石油在鄂尔多斯盆地的CCUS产业规划为例，综合考虑现有煤电、煤化工碳源运行和装置服役时限、CO2捕集能耗预测、CO2驱注入倍数与循环气量，以及盆地内煤基工业产业布局规划等限制因素，按2025年、2030年、2040年、2050年和2060年5个阶段完成鄂尔多斯盆地CCUS项目源汇匹配优化和阶段部署，匹配的CCUS/CCS项目群在2025—2060期间累计注入CO2约3.96×108t（含循环气0.48×108t），扣除各工艺能耗和泄漏排放后的CO2净减排量可达2.54×108t，净减排效率约为72.9%。

Abstract: This article focuses on energy consumed by CO2 capture from different sources, power consumed by CO2 compression and transportation in different landforms and over different distances, and energy consumption and leakage of the different CO2-flooding development stages. Using energy consumed and leaked by the CCUS projects and fugitive emission as the constraint conditions and net reduction of emission in the whole process of the project as the highest target of optimization, the CCUS source-sink matching method is formulated, which is in line with the dynamic reservoir development law and under the constraints of accounting carbon emission reduction. This method can serve as the decision-making basis for industrial distribution of CCUS technology and execution of the projects under the “dual carbon” goal. Take CNPC's CCUS industrial planning in Ordos Basin for example, this article comprehensively elaborates some constraining factors, such as operation of the existing coal-fired power and coal chemical carbon sources and the service life if the facilities, prediction of energy consumed by CO2 capture, gas volume injected and cycled for CO2 flooding, and planning of the coal-based industrial distribution in the basin. Source-sink matching optimization and distribution of the CCUS project in Ordos Basin will be completed in five stages, namely 2025, 2030, 2040, 2050 and 2060. The matched CCUS/CCS project group will cumulatively inject about 3.96×108 tons of CO2 (including 0.48×108 tons of recycled gas) in the duration from 2025 to 2060. The net reduction of CO2 emission can reach 2.54×108 tons, about a 72.9 percent net reduction efficiency, after deduction of energy consumed and leaked by all kinds of the technical process.
