中文摘要：
对松辽盆地齐家-古龙地区扶杨油层砂岩岩石学特征、孔隙类型与物性特征、胶结物种类及成岩作用特点及其分布与变化规律的详细研究表明：扶杨油层主要的成岩作用包括机械压实作用、胶结作用、溶蚀溶解作用。压实作用是导致砂岩储层质量变差的主要原因之一，可使孔隙度减少0．2％～22％；方解石是造成扶杨油层砂岩物性降低的主要胶结物，其次是石英次生加大；晚成岩阶段发生的油气侵位未能阻止石英的次生加大和部分自生矿物的沉淀；油气侵位后生成的酸性孔隙流体和通过断裂带渗入的大气水淋滤造成大量长石和方解石的溶蚀溶解，对储层物性起到了一定的改善作用。
英文摘要：
Detailed study on the rock property, pore types, measured porosity and permeability, cement and diagenesis of sandstones of the Fuyang Reservoir in Songliao Basin indicates that the mechanical compression, cementation and dissolution are the main diagenesis types. Compression is one of the main factors reduced the reservoir quality, which resulted in 0.2% -22% reduction of the total porosity. Cementation also plays an important role in the loss of porosity, and the major cement is calcite and quartz overgrowths. Homogenization temperature for inclusion suggests that quartz cementation and some authigenic minerals precipitation have continued after hydrocarbon emplacement during the late diagenetic phase. At the same time, the feldspar and calcite were dissolved by the organic acid liquids produced by reaction of hydrocarbon emplacement and penetrated meteoric water through the fault zones in strata, which resulted in lots of secondary porosity and contributed retention of reservoir quality of the sandstones.
