摘　　要：W井区马家沟组储层是该区域主要天然气富集层位,勘探潜力较大,前景良好。通过对沉积相特征、岩溶古地貌、岩石学特征、孔隙结构特征、物性特征等多方面综合分析,识别出了四种有利沉积微相,同时对储层特征进行了详细研究,以期为后续勘探开发提供依据。The reservoir of Majiagou Formation in Well W area is the main natural gas enrichment horizon in this area,with great exploration potential and good prospects.Through comprehensive analysis of sedimentary facies characteristics,karst palaeogeomorphology,petrological characteristics,pore structure characteristics,physical properties and other aspects,four favorable sedimentary microfacies were identified,and the reservoir characteristics were studied in detail to provide a basis for subsequent exploration and development.
