摘　　要：地层对比工作是一切地质综合研究首先要解决的问题。目前,河流相地层对比方法研究较多,但对冲积扇研究很少。本文以克拉玛依油田六中区克下组油藏为例,通过对野外露头、测井和地震等资料综合分析,提出了地层内部多级旋回性、底部超覆和填平补齐及沉积厚度等比例发育模式,并分析了形成这些发育模式的成因机制。在探讨地层发育模式的基础上,提出了标志层对比、旋回对比和等比例对比原则。应用桥式和三角网对比方法,对全区地层进行三维闭合,建立了精细等时地层格架,对下一步油田开发方案调整具有重要的指导意义。Stratigraphic correlation is the first comprehensive problem of all geological work to solve.Currently,studies on fluvial correlation are more,but less on alluvial fan.Taken the lower Karamay Formation reservoir of Six Middle Block in Karamay Oilfield as an example,based on analysis of outcrop,logging and seismic data and on discussion of stratigraphic development model,correlation principles of key bed contrast,cycles contrast and the contrast ratio were proposed.The fine stratigraphic framework in three-dimensional space was established with the bridge and the triangulation contrast method.It is of important guiding significance to the future oil development program adjustments.
