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(guò)使用現(xiàn)場(chǎng)灌注法測(cè)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(guò)對(duì)基本、 nearly 、 f 、 n -生成和弱相對(duì)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(jià)刻畫,并利用gp -內(nèi)射系的概念刻畫了-正則幺半群。
