Abstract

Abstract: In order to understand the hydrocarbon accumulation of Yingshan formation in Ma’nan structural belt of Maigaiti slope, the paper quantitatively describes the fluorescence spectrum of oil inclusions and identifies the oil inclusions with 4 fluorescent colors of orange, yellow-green, blue-green and blue-white by using peak wavelength (λmax), red-green quotient（Q）and QF535 parameters, which represents 4 different stages of oil and gas charging, respectively. The peak wavelength(λmax) and QF535 of oil inclusions are distributed in 4 different areas. The decrease of QF535 value reflects the gradual increase of the maturity of the oil trapped by inclusions. Hydrocarbon charging during stages Ⅰ,Ⅱ and Ⅲ made more contributions to the current oil and gas reservoirs of Yingshan formation than that of stage Ⅳ. The stage Ⅰ is low-maturity oil charging at the early stage and the stages Ⅱ, Ⅲ and Ⅳ are high-maturity oil charging at the late stage
