The acidizing technology for enhancing injectivity in conventional heavy oil production block 稠油常采區(qū)塊酸化增注工藝技術(shù)研究
Standard practice for determining water injectivity through the use of on - site floods 通過使用現(xiàn)場灌注法測定水注入能力的標(biāo)準(zhǔn)實(shí)施規(guī)范
Meanwhile , we describe injectivity conditions over a formal triangular matrix rings in views of the studies for essential , nearly , f , n - generated and weakly relative injective modules 通過對基本、 nearly 、 f 、 n -生成和弱相對內(nèi)射模的研究,進(jìn)一步討論了形式三角矩陣環(huán)上的內(nèi)射模。
In section 4 , we introduce the concepts of yj - injectivity acts and gp - injectivity acts , and get a characterization of yj - injectivity acts , and describe the - n - regular monoids with the concepts of gp - injectivity acts 第四節(jié)中引入了yj -內(nèi)射系和gp -內(nèi)射系的概念,給出了yj -內(nèi)射系的性質(zhì)及其等價刻畫,并利用gp -內(nèi)射系的概念刻畫了-正則幺半群。
The paper has presented a physical oil production technology by artificial earthquake , that is , vibration waves are caused in the oil - bearing formation , resulting in a series of vibration effects , there - fore , oil productivity or water injectivity is increased 摘要人工地震采油是通過地面可調(diào)頻振源進(jìn)行一定頻率的振動,產(chǎn)生振動波,在油層發(fā)生一系列的波動效應(yīng),達(dá)到增產(chǎn)增注目的的一項(xiàng)物理法采油技術(shù)。
