摘要
松辽盆地白垩系砂岩储层的粘土矿物主要由蒙皂石、伊利石、高岭石、绿泥石和混合层(蒙/伊和蒙/绿)粘土矿物组成。砂岩的粘土矿物组成、含量和它们在孔隙中的分布特征主要受成岩作用和沉积环境的控制,这些特征也是直接影响油层孔隙结构和产能大小的最主要因素。
Clay minerals in Cretaceous sandstone reservoirs in Songliao basin are ma- inly composed of smectite,illite,kaolinite,chlorite and smectite/illite and sm- ectite/chlorite mixed-layers.Compositions and content of these clay minerals, and their occurrence patterns in the sandstone pores are mainly controlled by diagenesis and depositional environment,These characteristics may directly affe- ct the pore texture and the production capacity of the reservoirs.
