Correlation of gas sources and genetic types of natural gas in Jurassic Shaximiao Formation of Zhongjiang gas field, Sichuan, China
摘要
Abstract
The genesis of natural gas and the source of natural gas in Jurassic Shaximiao Formation of Zhongjiang gas field are discussed so as to provide theoretical basis for gas exploration.Based on the geochemical data of natural gas compositions,carbon isotopes and light hydrocarbon,the genetic types of natural gas in this area are analyzed and the sources of natural gas are tracked on the basis of gas,source pairing parameters and carbon isotopic parameters of light hydrocarbons.It shows that the natural gas in the Shaximiao Formation is mainly natural gas and hydrocarbon gas,containing a small amount of non-hydrocarbon gas,and belonging to humic type kerogen cracking coal-type gas.Study of carbon isotope and light hydrocarbon indicates that natural gas in the area is organic genesis of coal-type gas.Gas sources correlation show that the coal-type gas in Shaximiao Formation is originated from the Member 5 of Upper Triassic Xujiahe Formation.It is considered that the gas reservoir of the Jurassic Shaximiao Formation in the Zhongjiang gas field is a secondary gas reservoir.关键词
