摘要: 以鄂尔多斯盆地上古生界深盆气藏为例,应用Leica Qwin和PVTsim软件对盆地中20多个钻孔的砂岩储层中的次生流体包裹体捕获温度、捕获压力、包裹体成分进行了模拟计算.同时采用Leica THSM G00气流冷热台对流体包裹体盐度进行了测定.根据以上信息的变化特征及盆地构造史和地热史分析结果表明,鄂尔多斯盆地上古生界深盆气藏在主形成期时,天然气由南向北运移.

Abstract: Inclusion contains much fluid information,from which the fluid migration rules can be concluded.In this paper,the compositions, trapping pressure and trapping temperature of secondary fluid inclusions of sandstone in twenties wells in the Upper Paleozoic deep basin gas reservoir in Ordos basin were simulated and calculated with the Leica Qwin and PVT sim software.The salinity of liquid inclusions was measured using Leica THMS G600 stage. According to the varying characters of above information as well as tectonic history and thermal history,it is concluded that the gas migrated from south to north in the primary forming period of Ordos deep basin gas trap.

Key words: Ordos Basin, Upper Paleozoic, deep basin gas, inclusion, trapping pressure, oil and gas migration
