YK气藏目前正处于开发阶段，需要对储层进行精细描述，而非均质性研究是储层评价的重要指标。通过对YK气藏亚格列木组岩心观察和测井资料的统计分析和研究，并结合沉积微相展布，定量或半定量的研究了亚格列木组的非均质性特征。研究表明，亚格列木组层内非均质性严重，层间非均质性中等，平面非均质性中等；上气层和下气层之间的隔层平面分布较为稳定，具有良好的封隔性；储层物性平面分布的非均质性受砂体发育程度及沉积微相的控制。通过储层非均质性研究，可以指导开发方案调整，为气藏的高效开发提供帮助。

YK gas reservoir is currently under development, the need for detailed reservoir description, and fine heterogeneity study is an important index of reservoir evaluation. This article based on core observation, testing and logging data of Yageliemu formation in YK gas reservoir, and combined with sedimentary microfaces, the heterogeneities of Yageliemu formation sublayers are been quantitatively and semi2quantitatively studied. The result shows that the innerbedded heterogeneity of Yageliemu formation is relatively high, the interbedded heterogeneity is medium, and the plane heterogeneity is is medium. The plane distribution of interlayer between above reservoir and under reservoir is relatively stability. The reservoir＇s physical property plane distribution is controlled by the heterogeneity of the development degree of sand and sedimentary microfacies. Based on the reservoir heterogeneity research, rationally divided development unit, it is offer help for reservoir efficient development.
