摘要: 准噶尔盆地克—百断裂带上盘最新钻井发现,在石炭系顶面之下较深的内幕火山岩区域获得工业油流。通过岩心、薄片、扫描电镜、主量元素和岩石物性等资料,明确了研究区石炭系内幕火山岩储集层特征及展布。研究表明,克—百断裂带上盘石炭系内幕储集层顶面最大深度位于石炭系不整合面以下800 m,岩相(岩性)以爆发相空落亚相(凝灰岩)和溢流相下部亚相(安山岩)为主,储集空间以次生溶孔和构造缝为主。不同岩相具有不同类型和程度的成岩作用,经历了不同的孔隙演化过程。溢流相上部亚相和溢流相下部亚相孔隙演化程度最高。冷凝固结作用控制其原生孔隙的形成,构造破碎作用及溶蚀作用至关重要。受构造和溶蚀作用控制的类和类储集层为有效储集层,主要分布于克—百断裂附近。

Abstract: From the latest drilling results of Ke-Bai fault zone in Jungger Basin,commercial oil are found in inside volcanic rocks of the Caboniferous which is far away beneath the Carboniferous unconformity. Based on the date of core,thin section,scanning electron microscopy,main elements and the physical properties,the characteristics and distribution of the inside volcanic reservoirs of the Caboniferous are definited. The study suggests the inside volcanic reservoirs are 800 m below the Caboniferous unconformity. The main types of lithofacies(lithology) are air fall subfacies of explosion facies(tuff)and lower subfacies of effusive facies(andesite). The main types of reservoir space are dissolved pore and tectonic fracture. Different kinds of lithofacies have different types of diagenesis and degrees of porosity evolution process. Upper effusive subfacies and lower effusive subfacies have the highest degree of pore evolution. Original interstice are controlled by the condensation. Tectonic broken and dissolution is essential to the reservoirs. Level-Ⅰ and level-Ⅱ reservoirs controlled by tectonic broken and dissolution are the effective reservoirs,which are distributed by the Ke-Bai Fault.

Key words: volcanic rock, Carboniferous, Ke-Bai fault zone, Junggar Basin
