张子枢在《石油消息》上撰文报道断陷盆地及复合盆地(前陆盆地及克拉通盆地的复合)天然气资源丰富,往往形成富气盆地(油气储量的当量比气大于油);在一个盆地内,天然气常常富集在某一个地区及某一层系。天然气的分布不均(全球已发现的26556个气田中,83.3％在北美),天然气的富集成带(已发现的102个巨型大气田,只占世界气田总数的0.4％,而储量却占总储量的60％),与大地构造挤压带有关。D.G.Howell(1992)发现其富集有明显规律,在靠近造山带
Zhang Zhishu’s article in the “Oil News” reported that faulted basins and composite basins (the combination of foreland basins and cratonic basins) are rich in natural gas, often forming gas-rich basins (where the equivalent gas-oil ratio is greater than that of oil); in a basin , Natural gas is often concentrated in a certain area and a certain system. The distribution of natural gas is uneven (83.3% of the 26,556 gas fields discovered in the world are in North America), and the gas-rich zones (102 giant gas fields have been discovered, accounting for only 0.4% of the world’s gas fields, 60% of the reserves), which is related to tectonic compression belt. D.G. Howell (1992) found that there is a clear regularity of its enrichment, close to the orogenic belt
