摘要: 在多气源条件下天然气扩散机制及其扩散系统划分的基础上,建立了一套多气源条件下的天然气扩散损失量的估算方法。在松辽盆地北部天然气扩散系统划分的基础上,通过天然气扩散损失量各计算参数的确定,利用所建立的多气源条件下天然气扩散损失量计算方法,估算松辽盆地北部4套主要烃源岩天然气扩散至地表的损失量,约为39.46×1012m3,占烃源岩生气总量的27.3%,表明扩散作用是天然气资源评价不可忽视的重要因素。

Abstract: Based on gas diffusion mechanisms and classified systems under multi-gas supply, the estimation method of gas diffusion loss amount is established and applied in estimation of the gas diffusion loss amounts up to surface of four sets of main source rocks in northern Songliao basin. The resulted amount of 39.46×1012m3 accounts for 27.3% of the total amount of generated gas in source rocks, showing that gas diffusion is a significant factor for gas resource evaluation.

Key words: Songliao basin, gas source rock, oil source bed, natural gas, diffusion coefficient
