| 摘 要： | 白垩系砂岩储层是松辽盆地主要的油气层，砂岩成分以石英，长石和岩屑为主，为长石砂岩，岩屑长石砂岩和长石质岩屑砂岩，储层孔隙包括粒间孔，粒内溶孔，铸模孔，胶结物内溶孔，裂缝等，储层孔隙演化经历了早、中、晚等成岩阶段，在中成岩阶段,晚成岩阶段早期和晚期有3次次生孔隙发育，其对储层性质有明显的改善。本区砂岩储集层可分为4个类型，且具有不同的分布规律。

| Abstract: | Cretaceous sandstone reservoirs are major oil layers in Songliao basin. Sandstone being made of quartz, feldspar and rock fragment, can be divided into arkose, lithic arkose and feldspthic lithic sandstone. Pore of reservoirs grain to grain pore, intergrain pore, intercrystalline pore and fracture. Pore evolution of reservoirs underwent three phase: early, middle and later diagenesis. There are three secondary pore belts which are found on middle and later diagenesis, and those belts are very important to improve quality of reservoirs. Reservoirs have been divided into four types and have different laws of distribution. |
