摘要 以岩心分析资料和大量的测井、生产动态资料为基础,通过对各种沉积相标志的分析,研究了克拉玛依油田八区中三叠统克上组储集层的沉积相类型、微相组成以及主要沉积微相的特征,认为八区克上组为一套冲积扇入湖形成的扇三角洲沉积,早期为扇三角洲前缘沉积,晚期过渡为扇三角洲平原沉积,作为储集层出现的主要是扇三角洲前缘的水下分流河道砂体、河口坝砂体和扇三角洲平原的辫状分流河道砂体,其次为水下分流间滩地及席状砂砂体。 : By means of the analysis for various facies markers, this article discussed the sedimentary facies type, microfacies buildups and their characteristics of Upper Karamay formation reservoir in the District No.8 of Karamay oilfield, based on core analysis, logging and production dynamic data. It is considered that the Upper Karamay formation in this area belongs to fan-delta sediments, which was formed by alluvial fan or braided stream directly entering lacustrine. The lower segment(S1 sandstone layer) is fan-deltaic deposits. A series of microfacies types have been differentiated, such as subaqueous distributary channel, inter-channel bottom land, channel-mouth bar, sheet sand and braided distributary channel, etc. On the basis of substrata division and vertical evolutionary conditions of the 10 substrata, 19 single sand-layers from S5-S1 have been analyzed.
