| 摘 要： | 论述了东北晚中生代断陷盆了Ｊ３－Ｋ１储层的孔隙组合特征及砂岩储层的孔隙结构类型，砂岩储层的孔隙组合为５种类型，正常粒间孔及缩小粒间孔组合；正常粒间孔及粒间扩大溶孔组合；粒间扩大溶孔及铸模孔组合；粒内溶孔及胶结物内溶孔组合，微孔和裂缝与少量原生粒间孔及残余缩小溶孔组合；特殊储层的孔隙组合因储层类型的不同而异，砾岩储层以砾间孔隙＋砾间填隙物孔隙为主，安山岩储层为气孔＋裂缝或气孔＋裂缝＋砾（粒）间空隙。

| Abstract: | In this paper, both pore combination characteristics and pore structuretyPes of the J3 -K1 sandstone reservoirs are discussed. The combinations of sandstonereservors are divided into five types: (1) the combinations of normal interpartical poreand contracted interpartical .pore; (2) the combinations of normal interpartical pore andinterpartical enlarged soluble pore; (3) the combinations of interpartical enlarged solublepore and moldic poreF (4) the combinations of soluble Pores in both the particles and thegelatinous rnaterials; (5) the combinations of Annor pore, fracture, a few of primaryinterpaftical pore and residual contracted soluble pore. The combination of special reservoirpores depends on the type of reservoir. Conglomerate reservoir is mainly the pores betweenthe conglomerate particles and the pores of the filling for the conglomerate particles.Andesite reservoir is gasous pore and fractrue or gasous pore,fracture and pores betweenthe conglomerate particles. The ancient weathered shell reservoir is soluble proe,solubleopening and fracture. The pore texture of sandstone reservoir is divided into:the type ofhigh porosity, high permeability coarse throat; the type of middle porosity, middlepermeability moderate throat;the type of middle porosity,low permeability fine throat andlow porosity, low permeability fine throat; the type of middle porosity, particular lowpermeability minor throat; the type of low porosity, particular low permeability minorthroat and the type of particular low porosity,particular low permeability minor throat. |
