摘要
利用铸体薄片、扫描电镜、物性和Ｘ－衍射分析资料，综合分析研究了吐鲁番－哈密盆地丘陵油田的油气储集层特征．侏罗系河道砂体和三角洲前缘砂体构成了丘陵地区主要的油气储集层．砂岩储层的储集空间包括粒间孔隙、残余粒间孔隙、溶蚀粒间孔隙、溶蚀粒内孔隙、填隙物内孔隙和裂缝孔隙．次生溶蚀孔隙和裂缝孔隙改善了砂岩储集层的孔隙结构．
he Characteristics of Jurassic reservoir in Qiuling oil-field have been studied by meansof optical examinatiom of casting thin sections, scanning electron microscope, physicalproperty and X-ray diffraction. The reservoir space is composed of intergranular pore,remnant intergranular pore, intergranular solution pore, intragranular solution pore, intramatrix pore and fissures, Delta front sand bodies and river channel sand bodies are mostimportant reservoires of oil and gas in Qiuling oil-field.
