摘要
本文给出了在地层条件(15.0MPa、75℃)下使用地层流体测定油水相对渗透率的实验方法,并与下列三种方法做了对比:(1)在常压50℃下,用洗净岩心,脱气原油;(2)在常温常压下用洗净岩心、精制油;(3)在常温常压下用洗净又恢复润湿性的岩心、精制油。比较结果表明,在常压下用洗净岩心,脱气原油和在常温常压下用恢复润湿性的岩心、精制油的测量结果与在地层条件下使用洗净岩心、含气原油测量结果基本一致,在常温常压下用洗净岩心、精制油测量的油水相对渗透率与前三者差别较大。
This paper presents an experimental method of determining the oil-water relative permeability at reservoir condition using reservoir fluid(live crude oil)and the results are compared with the following three cases:(1)Under local atmospherical pressure,50℃ using cleaned cores and chide oil.(2)Under room temperature and local atmospherical pressure using cleaned cores and re- fined oil.(3)Under room tempreture and local atmospherical pressure using restored-core and refined oil.A comparison of the results shows that water-oil relative permeabilities obtained from case 1 and case 3 are similiar to the re- suits obtained by using reservoir fluid under formation conditions,while the data from case 2 differs considerable from above cases.
