摘要
海拉尔盆地是在华力西褶皱基底上形成的中生代断陷盆地。扎赉诺尔群为盆地充填沉积,可划分为四套沉积组合,构成较完整的盆地充填序列,形成充填早期湖泊相、深陷期湖泊相和充填晚期湖泊相。砂岩形成于陆内深断陷盆地,物源为活动大陆边缘或大陆岛弧。主要储层可分为近岸水下扇砂(砾)岩体、浊积砂体和湖滨砂体三类不同的成岩模式。
Hailar Basin is a fault-depressed basin formed on Variscan folded basement. TheZhalainuoer Group in the basin could be divided into 4 sedimentary assemblages: 1. basalcoarse clastic section; 2. lacustrine coarse c1astic section; 3. lacustrine fine clastic section;4. coal-bearing clastic section. They constituted a relatively complete basin-filling se-quence. The sandstones in low maturity formed in inland deep fault-depressed basin andderived from active continent margin or island arc. The reservoir models can be classifiedas nearshore subaqueous fans, turbidity sandbodies and lake shore sandbodies.
