摘要: 天然气扩散散失率在定量评价天然气扩散对气藏破坏的影响方面具有重要意义。为获取其相对成熟的定量评价方法,在综合考虑扩散时间、岩石扩散系数、浓度梯度、含气面积和烃源岩排烃强度等影响因素的基础上,构建了苏里格气田陆源碎屑岩气藏天然气扩散的地质模型,并形成了一套陆源碎屑岩气藏天然气扩散散失率的定量评价方法。其基本思路:首先,依据烃源岩厚度、密度、原始有机碳恢复系数、残余有机碳含量及原始有机质气态烃产率等数据计算出生烃强度;其次,运用生烃强度乘以排烃系数,得出排烃强度;再次,依据菲克第一定律,推导出计算天然气扩散散失量的公式,并据此计算天然气扩散散失量,然后将其与含气面积相除,得出天然气扩散散失强度;最后,将天然气扩散散失强度与烃源岩排烃强度相除,得出天然气扩散散失率。依据该计算方法,对苏里格气田苏X区块天然气扩散散失率进行了定量评价,得出该区天然气扩散散失率大多为11%~17%,表明该气田天然气扩散散失率较低,天然气扩散散失对气藏破坏较小。其结果与苏里格气田地质储量、开发数据相吻合,表明该计算方法适用于陆源碎屑岩气藏天然气扩散散失率的定量研究。
