2、性能,以完善3-作液的配方和施工工藝,而裂縫性油氣藏裂縫的產(chǎn)狀、開度、方位等參數(shù)對(duì)工程實(shí)施效果有直接影響。因此,在室內(nèi)對(duì)巖心造縫使之能更真實(shí)地模擬地層顯得尤為重要。介紹了各種巖心造縫方法,分析了各自的優(yōu)缺點(diǎn),最后結(jié)合建立碳酸鹽巖縫洞型油氣藏物理模型的難點(diǎn),提出了一種新穎的縫洞微觀物理模型,并進(jìn)行了微觀物理模擬試驗(yàn),結(jié)果表明,該模型可較好地描繪凝膠堵水后水驅(qū)殘余油的動(dòng)態(tài)過程,這對(duì)認(rèn)識(shí)縫洞性油氣藏的封堵機(jī)理和研究水驅(qū)提高采收率的機(jī)理具有一定的指導(dǎo)意義。關(guān)鍵詞:縫洞型油氣藏;物理模擬;剖面調(diào)整;堵水;提高采收率中圖分類號(hào):TE344文獻(xiàn)標(biāo)識(shí)碼:A文章編號(hào):1n(_)卜0890(2O
