摘　　要：油气成藏期次分析是在沉积成岩史、构造发展史、热演化史及埋藏史四个地质历史特征分析基础上,来半定量反推成藏期次。在此,主要使用镇川8、米10和米19井盒8砂岩储层中的所测得的流体包裹体均一温度,对镇川8井盒8气藏进行埋藏史的恢复。研究表明：米脂盒8气藏,主要有两期天然气充注：第一期时间为190-175 Ma,第二期时间为155-97.5 Ma。Analysis of hydrocarbon reservoir formation period is to give a semi-quantitative reverse deduction based on four geologicalhistory characteristics of diagenesis,structural history,thermal evolution history and burial history. In this paper, homogenizationtemperature of fluid inclusions of He 8 sandstone reservoir of Zhen Chuan 8 well, Mi 10 well and Mi 19 well was mainly use to restorethe burial history of He 8 gas pool ofZhen Chuan 8 well. The research result shows that He 8 gas pool of Mizhi Gas-field has two majorgas filling process： the first stage of gas filling is 190-175 Ma, the second gas filing is 155-97.5 Ma.
