Abstract

Abstract: Caprock is the prerequisite for the accumulation of natural gas.Sealing of gas concentration is one of the important sealing mechanisms besides physical and pressure sealing.Natural gas in gas reservoirs may diffuse through caprock.Based on the study of the sealing mechanism of caprock,the geological and mathematic model of gas diffusion through caprock is established.The method for quantitatively evaluating the sealing of gas concentration in caprock is put forward.Concentration sealing characteristics of caprock on three gas reservoirs in Pingluoba structure of western Sichuam are discussed.

Key words: natural gas, gas reservoirs, caprock model

摘要： 盖层是天然气聚集的必要条件,盖层封闭作用除物性封闭、压力封闭之外,还有一种重要的封闭机理,即浓度封闭.本文在研究盖层浓度封闭机理的基础上,建立了天然气通过盖层的扩散模型,提出烃浓度封闭的定量研究方法,并以川西平落坝构造为例,分析了几个气藏的浓度封闭特征,说明浓度封闭对气藏的保存起重要作用.
