摘要:

 为了更加准确地评价盖层封盖油气能力,在研究盖层封盖油气作用及影响因素的基础上,利用盖层空间分布连续性和封闭能力有效性概念及加权平均法,建立考虑盖层空间分布连续性和盖层封闭能力有效性的盖层封盖油气能力的综合定量评价方法.将该方法应用于徐家围子断陷营城组14个火山岩气藏盖层封盖天然气能力的综合定量评价中.结果表明,徐家围子断陷营城组14个火山岩气藏中除4个气藏盖层封盖天然气能力为中等外,其余10个气藏盖层封盖天然气能力皆为较强和强,有利于天然气的聚集与保存.

关键词: 盖层封盖能力分布连续性能力有效性徐家围子断陷营城组    
Abstract:

A comprehensive quantitative evaluation method of sealing oil-gas ability of caprock was established based on the study of sealing oil-gas of caprock and its influence factors in order to exactly evaluate sealing oil-gas ability of caprock. The concept of space distribution continuity of caprock and sealing ability efficiency of caprock and the  weighting average method were used. The method was applied in evaluating comprehensively and quantitatively sealing gas ability of caprock of 14 volcanic gas reservoirs of Yingcheng formation in Xujiaweizi depression. Results indicate that the sealing gas ability of caprock of 10 volcanic gas reservoirs of Yingcheng formation in Xujiaweizi depression is stronger and the strongest,except the sealing gas ability of caprock of 4 volcanic gas reservoir is middle, which is favorable for gas to accumulate and preserve.

Key words: caprock    sealing ability    distribution continuity    ability efficiency    Xujiaweizi depression    Yingcheng formation
