摘要
由于龙门山地区会聚构造运动,地表露头与地下地震资料揭示了川西晚三叠世前陆盆地被卷入板内形变的构造地质现象。鉴于这一地区已经证实晚三叠世地层中富含油气,该文以获得的实际资料对晚三叠世前陆盆地形变年代、形变特征、形变运动(动力)学机制进行了深入分析,并着重分析了构造形变与油气成藏的关系。针对区内前陆盆地形变后所形成的3种不同类型(磁峰场、鸭子河、马井)的含气构造,文中讨论了其成藏的主控因素,并据此提出了该地区这一领域的油气勘探方向。
Abstract
Geological survey and geophysical interpretation revealed that the Late Triassic foreland basin in western Sichuan was involved in intraplate deformation as a result of squeezing activity in Longmenshan area.Due to its richness in hydrocarbon in the Late Triassic,the deformation age,characteristics and mechanism of the Late Triassic foreland basin were analyzed in detail,and the relationship between structural deformation and hydrocarbon accumulation was especially high lighted.In accordance with analysis three different gas-bearing structures developed in the foreland basin,the principal facters for hydrocarbon accumulation was discussed,and the favorable targets for gas exploration were proposed.
