摘要(Abstract)：

海拉尔盆地的基底是西伯利亚板块和中朝板块敛合后形成的古生代褶皱带。中生代,在先存断裂活动基础上发育了一系列断陷。断陷发育经历了初始张裂、强烈拉张、拉张裂陷、缓慢沉降、回返萎缩五个演化阶段。可划分出三类断陷六类构造带。断陷分割性强、差异升降明显、具有多物源、多烃源区、低地温梯度、后期岩浆活动相对较弱等特点。并指出盆地西部断陷油气形成条件优于东部,逆牵引构造帝、滑陷式背斜带等有利于油气聚集,并已获工业油流。
The basement of Hailaer basin is a Palaezoic fold zone formed after Siberian Plate & Sino-Korea Plate converged. Based on the existing fracture activity, a series of fault subsidence of Mcsozoic is developed. Development of fauit subsidence was undergone five evolution stages including initial tensional fault, strong tension, lensional rift,slow subsidence and backword shrieve.Six types of structural belts and three types of fault subsidence can be bivided in the basin. Fault subsidence is characterized by easy dividing, clear differential uplift, multiple source materials and oil source areas, low thermal gradient and magmatic activity relatively weaker at the late period. Formation condition of hydrocarbon of fault subsidence in the west of the basin is preferable to the condition in the east and reverse drag structure belt and slip faulted anticlinal belt is favourable to hydrocarbbon accumulation and commercial oil has been found in the basin.
