摘要
苏北黄桥二氧化碳气田是我国目前开发利用的最大气田之一,其地质储量为260×108m3,基本探明储量64×108m3.该气田深部由层状与块状气藏组成,浅部为富含氦气的天然气藏。根据二氧化碳气田的组成与同位素数据表明二氧化碳气来源于深部地幔。各气藏主要是通过裂缝运移、聚集而成。其成藏时间最晚。
Abstract
The carbon dioxide gas field in Huangqiao,North Jiangsu Province is one of the largest ones which have been developed and utilized at present in our country.Its geologic reserves is 260×108m3,and its basic explored reserves is 64×108m3.The deep of the field consists of stratified and massive gas pools,and the shallow consists of Helium-rich natural gas pools.The composition and isotopic data of the field indicate that carbon dioxide comes from deep mantle.Gas pools are mainly formed by migration and accumulation through fissures.They have later pool-forming times.
