摘　　要：利用研究区内20条剖面和3口测井的资料,通过薄片观察、扫描电镜、以及样品的孔隙度和渗透率的测定等资料的研究,对盆地内石炭系的砂岩储层特征及控制因素进行分析探讨。研究认为石炭系上统的羊虎沟组和靖远组孔隙较石炭系下统要发育,且以残余粒间孔和溶蚀型次生孔隙为最常见和最重要的孔隙组合类型;而对储集性能影响最为重要的因素是成岩作用的强度。By comprehensive understanding of profiles,the rock core,mm section ooservatlon, SEM,physical properties analysis and so on,the carboniferous sandstone reservoir characteristics and control factors are analyzed. Results show that porosity of the yanghugou formation and jingyuan formation of the Upper Carboniferous is more developed; the residual intergranular pore and secondary porosity are the most common and important combination types.The strength of the diagenesis is the supreme factor for the reservoir performance.
