摘要： 通过对我国不同类型盆地大中型气田天然气输导通道特征分析认为,断裂是我国大中型气田天然气运移的主要输导通道。通过定义和求取气藏天然气输导能力综合评价参数,对我国3种类型盆地以断裂为主要输导通道的46个大中型气田的输导能力进行研究认为,克拉通盆地大中型气田天然气输导能力最强,其次是前陆盆地,最小为裂谷盆地。通过定义和求取气藏天然气聚集效率参数,对我国46个大中型气田进行了研究认为,前陆盆地大中型气田天然气聚集效率最高,其次是裂谷盆地,最低是克拉通盆地。通过对我国46个大中型气田天然气聚集效率与其天然气输导能力综合评价参数之间关系研究认为,前陆盆地大中型气田天然气聚集效率受输导能力影响程度最大,其次是裂谷盆地,最小是克拉通盆地。前陆盆地形成高效大中型气田所需的天然气输导能力综合评价参数的下限值约1.6×10^-14m/s;裂谷盆地约2.0×10^-14m/s;克拉通盆地约5.2×10^-14m/s.

Abstract: The characteristics of gas migrating channels of large-and medium-sized gas fields in different types of basins of China are analyzed, it is believed that no matter what the basin types are, faults or fractures act as the main gas migrating channels. This paper presents the definition and the calculation of comprehensive evaluation parameters for gas transporting capability of gas pools and studies the capabilities of 46 large-and medium-sized gas fields in domestic three types of basins where the faults act mainly as gas migrating channels. The study shows that the large-and medium-sized gas fields in Cratonic basin possess the highest or strongest gas transporting capability, those in foreland basin have medium one and those in rift basin are the lowest. By definition, calculation and study, it is shown that the gas accumulation efficiency of foreland basin is the highest, that of rift basin is medium, that of Cratonic basin is the lowest. By study of relationship between the gas accumulation efficiencies and the comprehensive evaluation parameters, it is believed that the foreland basin is of the greatest effect of gas transporting capability on the gas accumulation efficiency, the rift basin is of medium one and Cratonic basin is of the smallest. This paper also presents that the minimum value of comprehensive evaluation parameters required for forming gas transporting capability of high efficiency of foreland basin is about 1.6×10^-14 m/s, that of rift basin is about 2.0×10^-14 m/s and that of Cratonic basin is about 5.2×10^-14 m/s.

Key words: large-and medium-sized gas fields, transporting capability, foreland basin, Cratonic basin, rift basin
