摘　　要：对子长油田30余口取心井的岩心观察和大量样品的铸体薄片、扫描电镜分析,研究了长2油层组形成的沉积相特征及储层特征,认为子长油田长2油层展布主要受沉积相控制,主要发育在三角洲平原分流河道砂体中,储层宏观、微观非均质性均较强,其中长21的非均质性要强于长22。The core sample observation and a large number of sections,scanning electron microscope testing from more than 30 coring wells were used to study the Chang 2 formation sedimentary facies and reservoir character.The Chang 2 reservoir distribution was controlled by sedimentary facies and mainly developed in the distributary channel of delta plain.The reservoir has a strong macro-and micro-heterogeneity and the heterogeneity of Chang 21 was better than that of Chang 22.
