摘　　要：通过岩心及测井资料分析,得到研究区T2k2油层组发育扇三角洲平原和前缘亚相沉积,扇三角洲平原亚相可分为分流河道、决口扇和分流间湾等微相。扇三角洲前缘亚相可分为河口坝、远砂坝和分流间湾等沉积微相。通过岩石相的划分和组合,结合岩心资料,建立测井沉积微相模式,确定沉积微相的展布特征,揭示了单砂体的空间分布规律,为准噶尔盆地西北缘砾岩油藏剩余油预测、开发调整提供了地质依据。According to a large amount of well logging and drilling core information, the fan - delta plain and fan - delta front sub -facies constitute the main depositional systems of T2k24 formation of Kelamayi Oilfield. The fan -delta plain suit - facies can be divided into distributary channel microfacies, flood fan microfacies, and distributary interchannel micro- facies. The fan - delta front sub - facies consists of sedimentary microfacies of mouth bar, far san dam,and distributary interchannel. Through dividing and grouping lithofacies, combining with core datum, a logging sedimentary microfacies model is established to determine the distribution feature of sedi - mentary microfacies and to reveal the space distribution law of single sand - body. Thus, it provides important geological foundation for remaining oil forecast and development adjustment of conglomerate reservoirs in west - north margin of Junggar Basin.
