摘　　要：通过岩心观察、岩石薄片鉴定、综合测井、粒度分析等资料,对克拉玛依油田XX地区白碱滩组的沉积特征进行综合研究,认为白碱滩组发育的是一套湖相-曲流河三角洲相沉积体系,鉴别出水下分流河道、河口砂坝、支流间湾、前三角洲泥、浅湖泥和浅湖砂坝6种沉积微相。编绘了各时期的沉积相平面图,分析了其展布特征与演化过程,推测该区白碱滩组沉积时期,湖平面经历了先上升,再下降,再上升的3个演化阶段。The sedimentary facies of Baijiantan Formation in the XX Area was studied by using core observation,rock thin section analysis,integral logging data and particle size analysis.It was considered that a set of lacustrine-meandering river delta sedimentary systems were developed in Baijiantan Formation.The sedimentary microfacies were identified including the underwater distributary channel,channel mouth bar,interbranch channel facies,predelta clay,shallow lake mud and shallow-lake bar sedimentary microfacies.Based on the analysis of distribution characteristics of sedimentary microfacies in plane and its evolution of the process,it is considered that during Baijiantan Sedimentary Period,the water level experiences three stages of evolution-rising,falling,and rising stages in this area through the drawing of sedimentary microfacies plane diagram.
