中文摘要	准噶尔盆地西北缘克拉玛依油田三叠系下克拉玛依组发育典型的干旱冲积扇储层,储层非均质性强,在长期注水开发过程中形成了多种窜流通道,并控制剩余油的形成和分布。从冲积扇储层构型解剖入手,综合应用测井、岩心、现代沉积等资料建立了冲积扇储层构型模式,在此基础上利用动、静态数据分析研究区窜流通道的类型和分布样式,冲积扇储层内部发育有别于其他碎屑岩储层的窜流通道类型,根据窜流通道的物性特征可分为大孔高渗通道和相对低渗通道2类。不同沉积相带内部发育不同成因的窜流通道:扇根内带为流沟系统,扇根外带为片流朵体骨架,扇中为高能水道。不同类型窜流通道的分布样式及其对剩余油分布特征的控制作用差异明显。流沟分布于单期槽流砾石体的上部,流沟之间相互交叉汇合形成树状组合,剩余油分布于槽流砾石体未被流沟切割的部位;片流朵体骨架在片流带内孔、渗性能最好,在三维空间内呈发束状发散,剩余油分布于单一片流朵体侧缘和上部;扇中高能水道为高孔、高渗的宽带状储集体,单一水道切割叠置频繁,剩余油富集在物性较差、规模较小的低能水道内;扇缘储层构型样式单一,径流水道规模小且多孤立分布,剩余油主要受控于开发井网与措施的完善程度。
英文摘要	Typical arid alluvial fan reservoirs are developed with strong heterogeneity in the Triassic Lower Karamay Formation of Karamay oilfield at the northwest margin of Junggar Basin.In the long-term process of water flooding development,a large number of water flooding channel were formed to control the formation and distribution of remaining oil.Based on architecture analysis of alluvial fan reservoirs,well logging,coring,modern sediments and other data were comprehensively used to establish the reservoir architecture model.On this basis,the type and distribution pattern of water flooding channels were analyzed using static and dynamic data.The water flooding channels developed in alluvial fan reservoirs are different from those in other clastic reservoirs.According to physical characteristics,these channels can be divided into two types,i.e.,high-porosity and high-permeability channel,and relatively low permeability channel.The water flooding channels with diversified geneses were developed within different sedimentary facies belts,i.e.,flow channel system in inner zone of root fan,sheet-flow lobe framework in outer zone of root fan and high energy channel in mid-fan zone.Significant differences exist in the distribution patterns of various water flooding channels and their controls on distribution characteristics of remaining oil.The flow channels are located in the upper part of single-phase channel flow gravels, mutually intersected and confluent to form a"tree-shaped" assemblage,while remaining oil is distributed in the section of channel-flow gravels,where no flow channel incision occurs.The sheet-flow lobe framework present the optimal porosity and permeability in sheet-flow zones,shown as"hair bundle-shaped" divergence in 3D space,while remaining oil exists at the lateral margin and upper part of single sheet-flow lobe.In the mid-fan zone,high-energy channels are high-porosity and high-permeability broad band-like reservoirs, where single channel incisions are frequently superimposed,while remaining oil is enriched in small-scale low-energy channels with lower physical properties.At the fan edge,the reservoirs are characterized by simple architecture pattern,where run-off channels are small in scale and mostly isolated,while remaining oil mainly depends on the improvement of well development network and measures.
