摘要
Affected by multistage tectonic movements,hydrocarbon accumulation in Silurian reservoirs of Tarim Basin is of uniqueness.Through systematical analysis methods for fluid inclusions,especially micro-beam fluorescent analysis method on a single fluid inclusion,we aimed to classify Kepingtage Formation hydrocarbon charging events of Well Shun 9 in Shuntuoguole low uplift and define their individual hydrocarbon accumulation ages.Results showed that Kepingtage Formation of Well Shun 9 located in the slope of Shuntuoguole low uplift is characterized by three oil charging episodes and one natural gas accumulation episode,the first oil charging episode occur in 417.5~409.5 Ma;the second oil charging episode occurr in late Hercynian(335.0~231.5 Ma),which is the major hydrocarbon accumulation period of this well field,oil might be from the Cambrian-Lower Ordovician and Middle-Upper Ordovician source rocks;the third episode occurr in middle-late Himalayan(20.1~19.7 Ma) oil are from the Middle-Upper Ordovician source rock,natural gas accumulation time is 23.5~15.3 Ma,and gas may be from the Cambrian-Lower Ordovician source rock.
