辽河坳陷基岩油气藏类型及其特征探讨

Discussion of type and characteristics of basement oil-gas reservoir in Liaohe depression

划分油气藏类型对于预测基岩油气藏具有重要的指导作用。通过对已知基岩油气藏进行解剖,发现基岩油气藏的形成与烃源岩关系密切。根据基岩与源岩的接触关系将辽河坳陷基岩油气藏分为三类二亚类。并立足于已知基岩油气藏,对不同类型的基岩油气藏的特征进行了阐述。

Classification on oil-gas reservoir plays an important guiding role in the prediction of basement oil-gas reservoir.By dissecting the proved basement oil-gas reservoir,it is discovered that the formation of basement oil-gas reservoir has a close relation to hydrocarbon source rock.Therefore,according to the contact relationship between bed rock and source rock,the basement oil-gas reservoirs in Liaohe depression are divided into three types and two secondary types.Based on the proved basement oil-gas reservoir,the characteristics of different types of the basement oil-gas reservoir are expounded.
