摘　　要：柴达木盆地冷湖四号构造E1+2主要油气储层砂体的分布受地层沉积影响,具有薄、多、散、杂的特点.用常规技术手段很难对其进行刻画,严重影响了勘探部署工作.该文利用沉积相研究、地震属性分析以及神经网络预测等技术手段,对该区下第三系路乐河组(E1+2)主要含油层段砂体展布情况进行刻画,进而对储层孔隙度和渗透率的平面分布规律进行预测.在此基础之上划定有利储层分布范围,为进一步勘探提供研究依据.Lenghu4# structure in the western Qaidam basin tectonic E1 ＋ 2 major oil and gas reservoir dis- tribution of reservoir sand affected by the stratum, has the characteristics of being thin, excessive, scattered and mixed. It is hard to depict with conventional techniques, furthermore, the exploration deployment will be seriously affected. This article will depict the paleogene Lulehe group （E1 ＋ 2） oil -bearing interval sand body distribu- tion, then plane distribution rule of reservoir porosity and permeability with the research of sedimentary facies, seismic attribute analysis and neural network prediction technology. Built upon this delimit the favorable reservoir distribution, provide research basis for further exploration.
