摘要
为了明确七东2区克拉玛依组油藏的优势挖潜区域,有效动用油藏,为挖潜开发方案的编制提供可靠的地质基础。基于地震、钻井、测井等基础数据,采用井震结合的方法建立了油藏的构造模型,采用岩相控制的克里金建模方法建立了油藏的属性模型,重新确认了构造和储层分布。七东2区克拉玛依组油藏纵向有7个砂组、26个含油小层、岩相横向变化快、储层平面及纵向非均质性较强。通过对油藏储层物性特征进行分析以及储量复核,明确该油藏属于受一定岩性及构造控制的岩性构造油藏,油层集中,主要发育在S7砂组。
To clarify the advantage area and provide a reliable geological basis for the effective development andpotential evaluation in the Karamay reservoir,based on thethe seismic,drilling and logging data,the constructed model of the reservoir is establishedby using a log and seismic data combined method,the attribute model is establishedby Krigingmethod with facies’control,that confirm the structure and the distributionof reservoir.There are7sand groups and26oil layersinKaramayoil field,the lithofacies change rapidly horizontally,and theheterogeneity is strong.Through the analysis of reservoir physical characteristics and reexamining the reserves,it is considered that the reservoir belongs to lithology structural reservoir.The reservoirmainly developed in S7sand group.
