| 摘 要： | 本文依据流体运动规律计算盖层与其下伏储集层之间的气势能差值,建立了评价盖层封闭天然气能力的方法。用其研究三肇地区青一段泥岩盖层对扶余油层中天然气的封闭能力,表明该方法可以定量评价盖层封闭天然气的能力,还可以将盖层封闭天然气能力的评价扩展到整个平面上,是一种较为全面和有效的研究方法。

| Abstract: | Based on the pattern of fluid movement, this paper establishes an evaluation method to thesealing ability of caprocks to gas by the gas potential difference between caprocks and reservoir,and applies it to the study of sealing ability of the mudstone caprock of the first member ofQingsankou Formation to the gas of Fuyu oil layer. The results indicate that the method not onlycan quantiatively evaluate the sealing ability of caprock to gas,but also can evaluate the sealing a-biiity of caprocks to gas on a plane. The method is more comprehensive and effective than the others else in study of sealing ability of caprocks to gas. |
