石油是不可再生資源,石油持續(xù)穩(wěn)產(chǎn)增產(chǎn)涉及國(guó)家的能源安全。隨著油田開(kāi)發(fā)難度逐年增大,第三次采油技術(shù)即提高采收率（EOR）技術(shù)不斷涌現(xiàn)。然而許多EOR技術(shù)難以大規(guī)模推廣是由于其微觀機(jī)理及微觀采油效率尚不明確。傳統(tǒng)膠結(jié)式人造巖心具有微觀結(jié)構(gòu)不可控,實(shí)驗(yàn)重復(fù)率低,流動(dòng)過(guò)程無(wú)法觀察等限制一直制約相關(guān)領(lǐng)域研究的發(fā)展。近年來(lái),微流控技術(shù)的發(fā)展為EOR技術(shù)研究與評(píng)價(jià)提供了新平臺(tái)。但傳統(tǒng)微流控芯片制備工藝難以滿足模擬儲(chǔ)層多孔介質(zhì)復(fù)雜結(jié)構(gòu)成型要求。因此,本文基于面投影微立體光刻技術(shù)開(kāi)展模擬儲(chǔ)層多孔介質(zhì)結(jié)構(gòu)與微流控制相關(guān)研究。采用自主研制的微立體光刻打印系統(tǒng)開(kāi)展模擬儲(chǔ)層多孔介質(zhì)微流場(chǎng)模塊制備方法研究,研究了光敏樹(shù)脂添加劑對(duì)增材制造工藝的影響規(guī)律。打印了三種用于實(shí)驗(yàn)研究的模擬儲(chǔ)層多孔介質(zhì)模塊。分析了打印精度的影響因素,優(yōu)化了微流控模塊打印過(guò)程工藝流程與參數(shù)。流體在近井地層中的流動(dòng)主要涉及多孔介質(zhì)的滲流,開(kāi)展了不同性質(zhì)流體流入儲(chǔ)層過(guò)程實(shí)驗(yàn)研究。分別進(jìn)行了微流控模塊親水和疏水性實(shí)驗(yàn)所提出的方法可以在空間上描繪具有疏水/親水區(qū)域的表面,該表面可作為微流控通道,并且該表面可應(yīng)用于具有其他類型基底的微流控器件。利用CO...
