摘　　要：通过对卡6井区卡001井、卡002井、卡003井及卡6井所取的岩心详细观察描述,从岩石学特征入手,结合测井资料及地震资料,划分出与储集层有关的砂砾岩相、含砾砂岩相、不等粒岩屑砂岩相、较纯砂岩相、粉砂岩相、泥岩相等6种主要的岩相类型,并指出它们在纵向上的沉积序列特征及特殊沉积构造特征,继而划分了沉积相类型及展布,得出下第三系紫泥泉子组(E1-2z)、安集海河组(E2-3a)储集层沉积相为辫状河三角洲前缘亚相。通过大量的储集层物性分析化验资料的研究,指出储集层物性特征,并对储集层进行了评价。Detailed descriptions of cores from Ka-001,Ka-002,Ka-003and Ka-6in Ka-6Well Block are presented in this paper.In light of these lithologic features,integrating with well log data and seismic data,six types of lithofacies of glutenite,con glom-eratic sandstone,inaquigran ular lithic sandstone,pure sandstone,siltstone and mudstone are classified into,along with their verti-cal sedimentary sequence features and special depositional structure features,followed by providing sedimentary facies patterns and distribution.It is con cluded that the Palaeogene Zini quanz formation(E 1-2 z),Anjihaihe formation(E 2-3 a)belong to braided river-delta front sub-fa cies.Furthermore,lots of reservoir data from lab petrophysical analysis are studied and the reservoir characteris-tics and qualities are evaluated.
