岩心采收率 meaning in English

recovery of core

Core test was studied to prove the technical possibility of the polymer gel cooperated with microbial enhanced oil recovery
并进行了大直径长管填砂岩心驱替试验，结果表明，调驱联作技术能够明显地提高岩心采收率。
This paper presents the results of investigating the destructive and oil - displacing capacities of species w3 , g12 and s11 for waxy crude oil from production well chang 74 : reduction of wax content by 7 - 11 % and of interfacial tension by 10 . 7 44 . 0 % ； reduction of high carbon number normal alkanes and enrichment of low carbon number ones ; production of gases ( mainly co2 and n2 ) and acids ; enhancement in oil recovery by 8 . 2 10 . 6 % ( in core experiments )
本文报道这几种菌在油藏条件下的生长情况，与昌74井原油的作用及岩心驱油结果：使原油含蜡量降低7 % 11 % ，使界面张力降低10 . 7 % 44 . 0 % ，使高碳数正构烷烃含量下降，低碳数正构烷烃含量增多，产酸产气，提高岩心采收率8 . 2 % 10 . 6 % 。
