根据天然气的地球化学特征、烃源岩的热演化和气势演化探讨柴达木盆地南八仙气田的气派，认为其天然气并非来自于赛什腾凹陷，而是主要来自于西侧的伊克雅汝乌凹陷。伊克雅汝乌凹陷是重要的煤成气生气中心，煤成气生气中心对气田的分布有明显的控制作用，处于伊克雅汝乌生气中心或生气中心附近的有效圈闭是煤成气聚集的有利场所，因此伊克雅汝乌、冷湖构造带东南段和马海—南八仙地区具有良好的天然气勘探前景。图3表3参5（赵林摘）
Based on the geochemical characteristics of natural gas, the thermal evolution and evolution of source rocks, the style of Nanbaxian gas field in Qaidam Basin is discussed. The natural gas is not from the Seth Teng depression, but mainly from the Iqa Ru Ukraine depression. The Ikya Ruu sag is an important coal-bearing gas center. The coal-derived gas center has obvious control over the distribution of gas fields. The effective traps near the gas center or gas center of the Ikya Ruyu are coal-based gas Therefore, the southeastern section of the Ikeja Ruwu, Lenghu tectonic belt and the Mahai-Nanbaixian region have good natural gas prospecting prospects.
