传统沉积微相的识别,主要是依据沉积特征、测井曲线相模式等资料进行逐井逐段地识别与划分.针对克拉玛依油田二区中西部八道湾组稠油油藏,应用沉积微相-岩石相综合分析方法,根据储层特征,识别并划分洪积扇扇中沉积相类型,在岩石相定量研究的基础上,进行了砾岩稠油油藏沉积微相的精细定量划分,表征了砾岩油藏沉积微相砂体之间在岩性、物性上的差异,并进一步总结了洪积扇扇中的沉积模式,研究了沉积微相-岩石相的平面展布规律,建立了不同类型沉积微相-岩石相储层地质知识库,认为扇中辫状河道粗砂岩相及辫状河道细砂岩相为主要的含油储集砂体.

The conventional way to identify sedimentary microfacies is mainly depending on sedimentary characteristics and well logging data to determine and divide well by well and interval by interval.Aiming at Badaowan heavy oil reservoir,Midwest Block II,Karamay Oilfield,based on the comprehensive analysis of sedimentary microfacies and lithofacies,as well as reservoir characteristics,the proluvial fan facies is identified and divided,according to quantitative lithology analysis,finely quantitative division of conglomerate heavy oil reservoir microfacies is carried out,the difference of lithologic and physical properties among the sand-bodies of conglomerate oil reservoir microfacies is presented,the sedimentary model of mid-proluvial fan is summarized,the distribution law of the microfacies and lithofacies on plane is studied,geological data base of different sedimentary micro facies-lithofacies reservoirs are established,it is indicated that braided channel course sandstone in mid fan and braided channel fine sandstone are the main oil-bearing sand bodies.
