龙门山冲断带前缘地区侏罗系出露与油气分布关系
|
摘要
龙门山冲断带前缘地区目前已发现的油气田或含油气构造主要分布在马角坝—通济场—双石断裂以东,统计分析结果表明52%分布在马角坝—通济场—双石断裂与广元—关口—大邑断裂之间(即前缘褶皱冲断带),其地表出露为侏罗系,其余则主要分布在广元—关口—大邑断裂以东的前陆坳陷带,地表为白垩系或第四系覆盖,认为侏罗系出露地区具有较好的油气勘探前景。通过研究区典型地震剖面解释,从构造变形角度解释这种油气分布特征的成因。
At present,main gas and oil fields or oil and gas structures discovered in the frontal area of Longmen Mountain thrust belt are confined to the east of Majiaoba-Tongjichang-Shuangshi faulting.The statistical result shows that about 52% of them are located between Majiaoba-Tongjichang-Shuangshi faulting and Guangyuan-Guankou-Dayi faulting(namely the frontal fold-thrust belt),in where the outcrops are mainly composed of Jurassic,and the rest are located in the foreland depressions to the east of Guangyuan-Guankou-Dayi faulting.The land surface is covered by Cretaceous or Quaternary.As a result,the Jurassic outcrop area is of a good prospect of petroleum exploration.And at last,the paper explains the reasons of hydrocarbon distribution from the viewpoint of structural deformation by the interpretation of typical seismic profiles in the study area.
