摘要(Abstract)：

海拉尔盆地钻探程度相对较高的凹陷为呼和湖、呼伦湖、乌尔逊、贝尔凹陷。根据这 4个凹陷现有的地化、地质资料 ,从平面和纵向上划分煤系烃源岩有机相。首先确定煤系烃源岩的分布范围 ,在此基础上利用煤系烃源岩的有机地球化学分析结果并结合沉积环境和地质特征制定有机相的划分标准 ,并依此标准将煤系烃源岩有机相划分为A相、B相、C相、D相 ,分别代表着该区煤系烃源岩生烃潜能的大小与优劣 ,为盆地煤系烃源岩的资源评价提供了可靠的参数。从整体看 ,海拉尔盆地的南屯组有机相性质优于其它层位 ,主要成烃有机相为B相、C相 ,有机质类型为Ⅲ—Ⅱ型 ,成烃贡献为中—好。最后通过有机相综合分析 ,明确了各凹陷不同相带的生烃潜力及成烃特征
Several depressions in Hailar Basin have been in-depth explored. The Organic facies of hydrocarbon resource rock in coal measures have been classified by the application of the geo-chemical data and geological data of these four depressions vertically and horizontally. On the basis of determination of the distribution scale of the hydrocarbon resource rock of coal measure strata , four facies ( A,B,C and D) have been set off by using the criterion established with the geo-chemical analyzing results of hydrocarbon resource rock combined with the environmental and geological characteristics,which stand for the qualities and grades of the hydrocarbon resource rock potential of these areas. These four organic faces criterions have provided reliable parameters for the evaluation of hydrocarbon resources rock in coal measure strata.From the top down,Nantun Formation of Hailar is better than other formations,which organic facies are mainly B and C, the organic types are III1-II.The hydrocarbon characteristics and its potential of different facies zones in depressions have been determined by the integrated researching of organic facies.
