Besides a microscopic analysis of fluid inclusions, the authors divided their types and, in combination with diagenesis and with the help of other useful information, determined the for- A mation stages of fluid inclusions and measured the homogenization temperature so as to analyze the hydrocarbon accumu1ation history of Yanchang Formation in the Yanchang Oilfield. The result shows that the homogenization temperatures of most fluid inclusions in Yanchang Formation are concentrated in the range of 105125 , with an
