摘要
原油中残存的油田化学剂及其与原油储层之间的作用产物,会对原油的后续加工带来不良的影响。以中国石油兰州石化公司加工的克拉玛依、塔里木、吐哈、长庆、青海西部五大油田生产的原油为例,研究油田化学剂对石油加工过程的影响与对策。研究表明,油田化学剂及其与原油储层之间的作用产物以油溶性、水溶性和不溶性三类物质残存于原油和常减压渣油中,主要对原油电脱盐脱水、常减压蒸馏、催化裂化和延迟焦化等单元操作造成不良影响。进一步就这些残余物对主要单元操作的生产装置、生产操作、产品质量以及FCC催化剂性能的影响进行了较为系统的研究,并在此基础上提出了应采取的技术、标准、信息与管理及基础研究方面的对策。
The residual oilfield chemicals and products from their interaction with oil reservoirs,will badly impact the follow-up processing.In this paper,the crude oil of five western Oilfields--Karamay,Tarim,Turpan-Hami,Changqing and Qinghai,which is processed by Lanzhou Petrochemical Company,is taken as an example to study the influence of oilfield chemicals on oil processing and countermeasures.The research and analysis show that the products are three kinds,i.e.,oil-soluble,water-soluble and insoluble in oil and atmospheric and vacuum residual oil,which mainly impact the unit operations of electric desalting and dehydration of crude oil,atmospheric and vacuum distillation,FCC and delayed coking etc.Systematically research about the residue impacts on the plants,operations and product qualities of each unit operation and performance of FCC catalyst is carried out,on the basis of which,the technology,standards,information,management and countermeasures of basic research are put forward.
