摘要： 分析孔隙成因类型及其控制因素，对于确定优质储层有重要意义。通过铸体薄片、扫描电镜及测录井资料分析认为，柴北缘西段古近系储层发育原生孔隙、次生孔隙和微裂缝三大类孔隙类型，原生孔隙可细分为压实残余粒间孔和胶结残余粒间孔，次生孔隙包括粒内溶孔、粒间溶孔和晶间微孔，微裂缝根据形成原因可分为压实微裂缝、溶蚀微裂缝。研究区储层孔隙类型主要发育以残余粒间孔为主的原生孔隙，其次发育粒内溶孔和粒间溶孔等次生孔隙，同时发育少量的压实微裂缝。柴北缘西段古近系储层孔隙类型主要受到沉积作用的控制，成岩作用次之，沉积作用对孔隙类型的控制体现在水动力强度的不同，水动力条件较强且成熟度较高的辫状河心滩、河床滞留及辫状河三角洲平原的分流河道、前缘水下分流河道储层砂体原生孔隙较为发育，在相同成岩作用背景下原生孔隙保留最完整，最有可能形成优质储层聚集区。

Abstract: Analysis of pore genetic types and controlling factors,has great significance to determine the high quality reservoirs.Using casting thin sections identification,scanning electron microscopy (SEM)and combining with logging and mud logging data,the results show that Paleogene reservoir developed three kinds of pore types in the northern margin of Qaidam Basin,i.e.,primary pore,secondary pore and microfracture pore.The primary pore can be subdivided into compacted residual intergranular pores and cemented remnant intergranular pores.The secondary pores include intragranular dissolved pores,intergranular dissolved pores and intergranular micropores.Microfracture pore can be divided into compacted microfracture pore and corrosion microfracture pore according to the formation reasons.The pore types of reservoir in the study area are mainly primary pores of the residual intergranular pores,and secondary pores such as the intragranular dissolved pores and intergranular dissolved pores,with a small amount of compacted microfracture pore.The Paleogene reservoir pore type is mainly controlled by sedimentation,followed by controlled diagenesis which located in northern margin of Qaidam Basin.The control of the pore types is different from the hydrodynamic intensity.The strong hydrodynamic conditions and high maturity of braided river island,riverbed detainment and braided river distributary channel of delta plain and front underwater distributary channel sand body reservoir primary pores are well developed under the background of the same diagenesis.The primary pore retention is the most completed,and most likely to form high quality reservoir accumulation area.

Key words: Qaidam Basin, Paleogene, Pore genetic types, Main controlling factors, High quality reservoirs
