【摘要】三叠系颗粒碳酸盐岩储层是四川盆地主要的产气层系之一,按成因可划分为残余粒间孔型滩相储层、岩溶型滩相储层(可进一步划分为早期岩溶型滩相储层、埋藏岩溶型滩相储层和表生岩溶型滩相储层)、白云岩化型滩相储层和复合型滩相
储层.它们的储集空间特征分别为:残余粒间孔型滩相储层以残余粒间孔+粒间溶孔
为主;早期岩溶型滩相储层以粒内溶孔+铸模孔为主;埋藏岩溶型滩相储层以溶蚀(扩)孔洞为主;表生岩溶型滩相储层多具有形态各异的岩溶孔洞系统;白云岩化型滩相储
层以晶间孔+晶间溶孔为主;复合滩相型储层为两种或以上成因类型相叠加;优质颗
粒滩碳酸盐岩储层最终形成绝大多数是以沉积相为基础叠加建设性成岩作用改造的产物.%The Triassic carbonate shoal reservoirs is one of the main gan producing strata in Sichuan basin.They can be genetically divided into residual intergranular pore type of carbonate shoal reservoirs,karstification type of carbonate shoal reservoirs (further divided into syndepositional karstification type of carbonate shoal reservoirs,burial karstification type of carbonate shoal reservoirs and supergene karstification type of carbonate shoal reservoirs),dolomite type of carbonate shoal reservoirs and composite type of carbonate shoal reservoirs.Residual intergranular pores and intergranular dissolved pores are main reservoir space of residual intergranular pore type of carbonate shoal reservoirs.Isolate intragranular
corroded pores and mould pores are main reservoir space of syndepositional karstification type of carbonate shoal reservoirs.Solution pores and holes are main reservoir space of burial karstification type of carbonate shoal reservoirs.The difference of scales and forms of karst pores and holes are main reservoir space of supergene karstification type of carbonate shoal reservoirs.Intercrystal pores and intercrystal solution pores are main reservoir space of dolomite type of carbonate shoal reservoirs.The various reservoir spaces including complex pores system and complex holes system are main characteristics of composite type of carbonate shoal reservoirs.The further analysis result of the main control factors of types of genetic carbonate shoal reservoirs shows that the high quality carbonate shoal reservoirs are formed by sedimentary facies and constructive diagenesis modification.
