摘要： 针对渤海油田稠油开采需要,中国科学院化学研究所和中海油研究总院研制了稠油活化剂(ICAJ)。作为单一化学剂,配制工艺简单,注入设施及流程简便,易于操作管理,操作运行及维护成本低。对其驱油性能进行了试验研究,验证了ICAJ具有很强的亲和原油能力和较好的乳化分散稠油的能力。岩心驱油结果表明,ICAJ能扩大波及体积,提高洗油效率,更适合稠油开采。物理模拟实验显示,其提高采收率幅度高出水驱15%左右,可在油田现场推广应用。

Abstract: To meet the demand for heavy oil production in Bohai Oilfield, Chemical Research Institute of China’s Academy of Sciences and CNOOC Research Institute jointly developed heavy oil activating agent (ICAJ). As a single chemical agent, ICAJ is simple in formulation process, convenient in use of injection facilities, easy for operation and management, and cost-effective in service and maintenance. The test of its oil displacement ability confirms that ICAJ has a strong affinity of heavy oil and is able to emulsify and disperse heavy oil. The core flooding results show that ICAJ can enlarge swept volume and improve oilwashing efficiency, more appropriate for heavy oil production. The physical simulation experiment indicates that the agent can raise EOR by about 15 percent as compared to water flooding. It can be put into wide application in oilfields.
