黑龙江北部孙吴—嘉荫盆地构造特征、演化及石油地质条件
|
摘要
重力解释孙吴—嘉荫盆地基底埋深一般在0.1～2.5 km,基底形态具有北东走向的"三断两隆"的构造特征,自西向东称孙吴断陷、茅栏河隆起、沾河断陷、富饶隆起和嘉荫断陷。地震解释基底深度一般在0.1～6.3 km,并据之进一步划分了断陷的次级构造单元。孙吴—嘉荫盆地的形成和演化与南部的松辽盆地颇为相似,大致经历了前裂陷、断陷、坳陷和萎缩4个阶段。下白垩统淘淇河组、上白垩统永安村组和太平林场组埋藏较深,厚度较大,烃源岩达到成熟阶段,储层发育,物性较好,为油气勘探的主要目的层。对沾河断陷和嘉荫断陷油气勘探有利区做了进一步预测,确定乌拉嘎凹陷是嘉荫断陷最有利的勘探区,确定沾河向斜是沾河断陷最有利的勘探区。
The data of gravity and aeromagnetic surveys revealed that the depth of buried basement of the Suwu-Jiayin Basin was 0.1-2.5 km,and the basin could be divided into three depressions sandwiched in two uplifts with NE trend,which were named,in eastward order,the Sunwu Fault-Depression,the Maolanhe Rise,the Zhanhe Fault-Depression,the Furao Rise and the Jiayin Fault-Depression.The seismic data showed the basemental depth of the basin being 0.1- 6.3 km,and sub-order tectonic units of the fault-depressions were divided further.The forma- tion and evolution of the Suwu-Jiayin Basin seemed similar to the Songliao Basin,which went through four stages,namely,the pre-extensional stage,the faulting depression stage,the down- warping stage and withering stage.The source rocks in the Lower Crataceous Taoqihe Forma- tion,the Upper Crataceous Yongancun and Taipinglinchang formations were matured and the reservoir was good,which were main exploration layers in the basin.According to the evalua- tion of the petroleum geological conditions,the paper forecasted that the Wulaga Sag in the Jiayin Fault-Depression and the Zhanhe syncline in the Zhanhe Fault-Depression should be po- tential exploration areas.
