摘　　要：针对沙罐坪石炭系气藏储层有效厚度不大,以低孔低渗为主,储层非均质性较强等特征,利用储层描述技术重点开展了地层及沉积相分析、储层缝洞特征描述、储层纵横向展布规律等方面的研究,并在储层描述的基础上应用地质建模技术对沙罐坪石炭系气藏实现了科学的相控三维地质建模,直观地反映了沉积相与储层属性参数在三维空间的展布特征,较好地描述了整个石炭系气藏储层的非均质性以及储层的展布特征,为该气藏实施挖潜开发提供了地质基础。Dominated by low permeability and low porosity,Shaguanping Carboniferous reservoir is characterized by small effective thickness and more strong heterogeneity. Based on these characteristics,some research on formation and sedimentary facies,fracture-vug description,and reservoir distribution in both vertical and horizontal were carried out by reservoir description technology. Moreover,a facies-controlled 3D geological modeling was fulfilled to Shaguanping Carboniferous reservoir,which not only reflects an 3D spatially distribution of both sedimentary faceis and attribute parameters directly but also describes both heterogeneity and reservoir distribution of whole Carboniferous reservoir very well. The research provides a geological basis for further development of Carboniferous reservoir.
