通过对塔里木盆地塔中地区断裂附近的志留系油藏含氮化合物和饱和烃、芳烃成熟度参数运移示踪研究发现,志留系油藏的运移和聚集成藏均与断裂作为优势通道的垂向运移有关.综合分析认为塔中志留系油藏运移和聚集成藏的主控地质要素是走滑断裂,发育于奥陶纪至晚海西期.塔中志留系下步勘探可以通过精细研究走滑断裂的形成演化与分布,明确有利油气聚集区,落实有利目标. By tracing the parameters of nitrogenous compounds, saturated hydrocarbon and aromatic hydrocarbon in the Silurian reservoirs near Tazhong area in the Tarim Basin, it is found that the migration and accumulation of Silurian reservoirs are both favorable and fracture-dominant The vertical migration of the channel.The comprehensive analysis shows that the dominant geologic element of the migration and accumulation of the Tazhong Silurian reservoirs is strike-slip faulting, developed from Ordovician to late Hercynian. Subsequent exploration can finely study the formation, evolution and distribution of strike-slip faults, clarify the favorable hydrocarbon accumulation areas and implement favorable targets.
