通过分析天然气及其伴生原油的地球化学特征，结合区域的地质构造形态，认为克拉美丽气田的油气在滴水泉西断裂两侧来源不同。断裂北部的油气来自滴水泉凹陷的石炭系腐殖型的烃源岩；断裂南部的油气主要来自石炭系烃源岩，混有部分来自东道海子凹陷二叠系腐泥型源岩供给的油。%Kelameili gas field is another important discovery and has huge reserves in the Junggar Basin exploration in recent years, which produces natural gas associated with a small amount ofoil mainly existing in the Carboniferous volcanic rocks. This paper mainly analyzes geochemical characteristics of natural gas and associated crude oil. According to the regional geological structure forms, the oil and gas in both sides of the dripping springs west fault in Kelameili gas field have different sources. Oil and gas in the north of the fault mainly come from humic source rocks of Dishuiquan depression Carboniferous. Oil and gas in the south of the fault mainly come from Carboniferous humic source rocks, which are mixed with some crude oil coming from partial sapropel source rocks of Dongdaohaizi depression Permian supply.
