摘　　要：CO_2捕集、运输、驱油与封存(CCUS)全流程是CO_2减排的有效途径。为了进行CCUS全流程优化设计,保证CCUS技术的顺利实施,根据建立的CCUS全流程模型对其各子系统及全流程系统进行优化设计。采用遗传算法得到多元优化问题的最优解集。以某实际CCUS项目为例进行仿真,结果表明:在CCUS全流程的建设总成本中,CO_2捕集系统费用约占60%,CO_2运输系统费用约占15%,CO_2驱油与封存系统费用约占25%;CCUS全流程建模的优化设计降低了流程建设的总成本,验证了该方法的有效性。The whole process of CO2 capture,transportation,oil displacement and storage(CCUS)is the effective way to reduce CO2 emission.In order to optimize the whole process of CCUS and ensure the smooth implementation of CCUS technology,the whole process model of CCUS is established to optimize and design the subsystems and the whole process system of CCUS.The genetic algorithm is used to get the optimal disaggregation of diversified optimization problems.A actual CCUS project is taken as an example to simulate,and the results show that the cost of CO2 capture system accounts for 60%of the total cost of the whole process construction,the cost of CO2 transportation makes up 15%,and the cost of CO2 oil displacement and storage sees a share of 25%.The optimized design of CCUS whole process modeling can reduce the total cost of the process construction,and the effectiveness of the method has been verified.
