摘　　要：以岩心观察、测井和生产动态资料为基础,通过对岩石组合、沉积构造、测井相分析和砂体形态等沉积相标志的分析,对克拉玛依油田一中区上克拉玛依组沉积相类型及沉积微相展布进行了研究.结果表明:一中区上克拉玛依组发育辫状河三角洲平原亚相和辫状河三角洲前缘亚相.其中,S52-2单层发育辫状河三角洲前缘亚相,以水下分流河道、河口坝、席状砂和三角洲前缘泥等微相为主;S52-1到S51-1单层、S4砂组和S1砂组各单层发育辫状河三角洲平原亚相,以分流河道、溢岸砂和分流间湾等微相为主.Based on core observation, logging and production performance data, sedimentary facies of the Upper Karamay Formation in middle block 1 of Karamay Oilfield are studied by analyzing the rock association, sedimentary structure, logging facies and sand body shape. The results show that braided river delta plain subfacies and braided river delta front subfa- cies are developed in the Upper Karamay Formation of middle block 1. Among them, braided river delta front subfacies are developed in Sa 2-2, which include underwater distributary chan- nel, mouth bar, sheet sand and delta front mud. Braided river delta plain subfacies are devel- oped in Ss2-1 to S51-1 , S4 and S1, which mainly develop distributary channel, overbank sand and interdistributary bay.
