摘要(Abstract)：

通过川东复兴场地区嘉陵江组储层薄片观察及物性资料对嘉一—嘉二2段储层特征、控制因素的研究表明,复兴场地区嘉一—嘉二2段储集岩的储集性能最好的是白云岩类,其次为细粒灰岩类。白云岩类储层发育有粒间、粒内、晶间、晶内溶孔和裂缝等储集空间,主要构成孔隙—裂缝型的嘉二2段储层。而灰岩类储层只发育有孔隙性溶孔(洞)和缝,主要构成裂缝—孔隙型的嘉一段储层。通过孔—渗、厚度分布对比可见,嘉二2段储层的储集性优于嘉一段,是嘉陵江组主要的储层发育段和油气聚集最有利部位,其原因是嘉陵江组储层受沉积、成岩和构造作用的控制和影响。沉积作用使储层早期分异,白云石化作用对白云岩类进行了改造,提高了嘉二2段储层储集性,构造作用为以上作用提供了条件。
Based on the flake observation and physical properties data of reservoir in Jialingjiang Formation in Fuxingchang region of East Sichuan,detailed study on the reservoir properties and controlling factors of J1J22 Members is carried out.Result indicates that the best reservoir rock is dolomite category and the second best is fine limestone in J1-J22 Members.Intergranular and intragranular dissolved pores,intercrystalline and intracrystalline pores and fractures are developed in dolomite category reservoir,mainly in J22 Member,forming pore-fracture type of reservoir.Only pored dissolved holes and fractures are developed in calcareous rock reservoir,mainly in J1 Member,forming pore-fracture type of reservoir.Comparison of porosity,permeability and thickness shows that reservoir property of J22 Member is better than J1 Member,as the best position of reservoir development and hydrocarbon aggregation in Jialingjiang Formation.The reason is that Jialingjiang Formation reservoir is under the control and influence of deposition,diagenesis and tectonism.Deposition as basic factor caused early reservoir differentiation-mainly calcareous rock in J1 Member and dolomite in J22 Member.Dolomite lithofaction reconstructed dolomite rocks,playing a key role in improving reservoir property in J22 Member.Tectonism provides conditions for the above activities.
