摘　　要：根据钻井、岩心及薄片分析等资料,并结合物性和储层储集空间资料,对南门场石炭系储层特征进行了研究。综合研究结果表明:南门场石炭系为沉积黄龙组地层;储层岩性主要为白云岩;储集空间主要包括粒间(内)溶孔、砾间(内)溶孔等,孔隙型溶洞及构造缝也较为发育,总体上属于裂缝-孔隙型储层;储层类型以Ⅱ、Ⅲ类储层为主,表现出低孔、低渗的特征;Ⅰ类储层主要分布于C2hl2段,平面上零星分布,Ⅱ、Ⅲ类储层主要分布于C2hl2段及C2hl3的中下段,平面上分布广泛。The characteristics of carboniferous reservoirs in Nanmenchang were studied based on the data of drilling,core and sheet analysis,combined with the data of physical properties and reservoir space.The comprehensive re search results showed that:Nanmenchang Carboniferous is a sedimentary Huanglong Formation stratum.Reservoir li thology is mainly dolomite.The storage space mainly includes intergranular(inner)caves,intergranular(inner)caves,etc..Porous caves and structural seams are also more developed.Generally,they belong to fissure-pore reservoirs.The reservoir types are mainly type II and III reservoirs,showing the characteristics of low porosity and low permeability.Class I reservoirs are mainly distributed in C2hl2,sporadic distribution on the plane,type II and III reservoirs are mainly distributed in C2hl2 and C2hl3 middle and lower segments,and are widely distributed on the plane.
