| 摘 要： | 本文利用钻井取芯资料和铸体薄片、扫描电镜、X衍射等分析化验资料,对准噶尔盆地车排子地区侏罗系低渗储层的孔隙结构特征及影响因素进行了研究.结果表明:该区孔隙类型多样,孔径中等偏小;排驱压力和中值毛管压力偏高,喉道细小;孔喉分选较差、连通性较差、孔隙结构非均质性强.孔小喉细、渗透率低的主要原因有三方面:原始孔渗条件差;砂岩...

| Abstract: | Based on the analysis of the drilling core,cast thin section,scanning electronic microscope and X-Ray Diffraction,pore structure and influencing factors in the Chepaizi area of the Junggar Basin are studied.Results show that there are many kinds of pore types,and the pore size is moderate and small.Displacement pressure and median pressure are high,and the throats are small.The ores and throats have poor sorting,the connectivity is poor too,and the pore structure has strong heterogeneity.The causes of the s... |
