摘　　要：通过对准噶尔盆地东部彩43井区白垩系-石树沟群储层微观特征研究,认为整体储集物性较好,白垩系优于石树沟群,储层控制因素主要受埋深、粒度和填隙物的影响,粒度偏细,孔隙发育。储层粘土含量低,粘土矿物的产状-含水粘土膜是造成油层电阻率偏低的主要原因之一。By study on the reservoir microsopic characteristic of Cai 43 wellblock chalk system and shishugouqun of the Juggar Basin,it is found that reservoir properties of matter are better;the chalk system is superior to shishugouqun,in addition,the reservoir controlling factor is affected by bury depth 、grain size and filler,so the grain size is too fine and pore develops.The reservoir of low clay content and the occurrence of clay rock is one of the main reasons for low resistivity of oil layers..
