| 摘 要： | 辽东湾旅大地区古近系储层砂岩类型主要为长石砂岩和岩屑长石砂岩，岩屑成分主要为岩浆岩和较多的变质岩.胶结类型以孔隙式胶结为主，孔隙类型以次生孔隙为主.砂岩成岩作用包括压实作用、胶结作用、溶蚀作用等，其中胶结作用使储层原生孔隙迅速变差，而溶蚀作用是次生孔隙发育的主要因素.成岩作用对砂岩储集层的孔隙结构起着显著的改造作用，孔隙度演化与成岩阶段有较好的对应关系. |

| Abstract: | The Paleogene reservoirs in Lvda area of Liaodong Bay are characterized by feldspar sandstone and lithic feldspar sandstone.The lithoclasts include mainly magmatic rocks and some metamorphic rocks.The cementation type is dominated by pore cementation,with mainly secondary pore.The diagenesis of the sandstones involves compaction,cementation,dissolution and replacement,of which the cementation decreases the primary pores of reservoir rapidly,whereas the dissolution increase the secondary pores.Therefore,the ... |
