摘　　要：从储层岩性特征、孔隙特征及储层物性特征等方面分析了克拉玛依油田八区克上组砂砾岩油藏储层特征。研究表明,克拉玛依油田八区克上组砂砾岩油藏储层以砂质砾岩和砾质砂岩为主,结构成熟度和成分成熟度都不高;孔隙类型以粒间孔为主,其次为粒内孔和溶孔,溶蚀作用对孔隙的形成具有重要的影响;储层储集性能总体上是中低孔中低渗。On the basis of previous researches,this paper studies the reservoir lithology,the characteristics of pore and physical properties are used to analyze the conglomerate reservoir characteristics of Upper Karamay Formation in the 8th Area of Karamay Oilfield.The results show that the study area is mainly of sandy conglomerate and gravelly sandstone, the structural and compositional maturity is not high;The types of pores are mainly of intergranular pore,followed by the intragranular solution pores and dissolution pores.Dissolution has an important effect on the formation of the pores.The overall reservoir performance of the Upper Karamay Formation in the study area is low-middle porosity and low-middle penetration.
