【摘要】：基于準(zhǔn)噶爾盆地西泉地區(qū)火山巖儲層特征研究較薄弱的現(xiàn)象,通過25口井的巖心觀察、鑄體薄片、掃描電鏡及高壓壓汞等分析,以產(chǎn)能大小為依據(jù),將火山巖儲層分為4類,對火山巖儲集空間類型及組合、微觀孔隙結(jié)構(gòu)特征進(jìn)行分類評價。根據(jù)研究區(qū)火山巖儲層面孔率及優(yōu)勢儲集空間組合關(guān)系:Ⅰ類為氣孔+溶蝕擴(kuò)大孔、溶蝕孔+裂縫型,Ⅱ類為氣孔+構(gòu)造縫(溶蝕縫)型,Ⅲ類為氣孔+溶孔型,Ⅳ類為孤立小孔隙型,面孔率依次降低�；鹕綆r儲層不同類型微觀孔隙結(jié)構(gòu)特征表明:Ⅰ類儲層發(fā)育大孔隙、粗喉道,為優(yōu)勢儲集層;Ⅱ類和Ⅲ類儲層發(fā)育大—中孔隙,中—細(xì)喉道,為較好到中—差儲層;Ⅳ類儲層發(fā)育小孔隙、細(xì)喉道,為致密儲層。在此基礎(chǔ)上,結(jié)合測井資料,建立了研究區(qū)火山巖儲層分類評價標(biāo)準(zhǔn)。
[Abstract]:Based on the weak study of volcanic reservoir characteristics in Xiquan area, Junggar Basin, the volcanic reservoir is classified into 4 types by core observation, casting thin section, scanning electron microscope and high pressure mercury pressure analysis in 25 wells. The types and assemblages of volcanic reservoir space and the characteristics of microscopic pore structure are classified and evaluated. According to the relationship between the porosity of volcanic reservoir and the combination of dominant reservoir space in the study area, the types I are enlarged pore dissolution, the fracture type is solution pore, the second type is pore structure fracture (dissolution fracture), and the third type is pore dissolution.
